If you need to use an expression like /\/word\:\w*$/, be sure to escape your backslashes: new RegExp( '\\/word\\:\\w*$' ). – Jonathan Swinney Nov 9 '10 at 23:04

nstead of using the /regex\d/g syntax, you can construct a new RegExp object: var replace = "regex\\d"; var re = new RegExp(replace,"g");

adamsmith October 15, 2018 Add Item by Identifier will work for any DOI registered in Crossref or a half-dozen other DOI registrars Really? I thought we currently "just" covered CrossRef, DataCite, and Airiti? - which does still mean it almost always works; that's probably 95%+ of active DOIs, but if there's code already that covers others, that'd be good to know as I was just going to put some work towards that. dstillman October 15, 2018 We also have DOI translators for EIDR and mEDRA.

Behind the scenes improvements to the REST API Patrick Polischuk – 2021 July 06 In REST APICommunity UPDATE, 24 August 2021: All pools have been migrated to the new Elasticsearch-backed API, which already appears to be more stable and performant than the outgoing Solr API. Please report any issues via our Crossref issue repository in Gitlab.

Open Citation Identifiers Each Open Citation Identifier [[OCI]] has a simple structure: the lower-case letters "oci" followed by a colon, followed by two numbers separated by a dash (e.g. https://w3id.org/oc/index/coci/ci/02001010806360107050663080702026306630509-02001010806360107050663080702026305630301), in which the first number identifies the citing work and the second number identifies the cited work. For citations in which the citing and cited works are identified by DOIs, which includes all the COCI citations, the OCI is created in the following manner, as explained more fully here. Each case-insensitive DOI is first normalized to lower case letters. Then, after omitting the initial doi:10. prefix, the alphanumeric string of the DOI is converted reversibly to a pure numerical string using the simple two-numeral lookup table for numerals, lower case letters and other characters presented at https://github.com/opencitations/oci/blob/master/lookup.csv. Finally, each converted numeral is prefixes by a 020, which indicates that Crossref is the supplier of the original metadata of the citation (as indicated at http://opencitations.net/oci). OCIs can be resolved using the OpenCitations OCI Resolution Service.

Each case-insensitive DOI is first normalized to lower case letters

DOI registration agencies such as Crossref, DataCite and mEDRA collect bibliographic metadata about the works they link to.

Internet gets more reliable

my main frustrations are around the lack of the very basic things that computers can do extremely well: data retrieval and search. I'll carry on, just listing some examples. Let's see if any of them resonate with you:

youtube videos, even though most of them have subtitles hence allowing for full text search?

the tool I've developed

I want URLs to address information and represent relations. The current URL experience is far from ideal for this.

a more realistic and plausible target: using my digital trace (such as browser history, webpage annotations and my personal wiki) to make up for my limited memory

Tip 8 You can click the DOI and URL field labels to open the field link:

Tip 5 You can convert the contents of the "Title" and "Publisher" fields to either sentence or title case by right-clicking the field and using the Transform Text menu.

Tip 3 To see the number of items in the selected library or collection, click an item in the middle column and use the Select All shortcut:  Command + A on Mac OS X or Control + A on Windows and Linux  A count will appear in the right column:

"Control" key on Windows

Tip 2 Press "Shift" and “+” (plus) on the keyboard within a collections list or items list to expand all attachments, and “-” (minus) to collapse them.

More recently, there has been a strong movement to move the web over from HTTP to the more secure HTTPS protocol. Technical changes also made it possible to link DOIs via the shorter doi.org instead of dx.doi.org. Together, this let Crossref change its recommended format to https://doi.org/10.1037/rmh0000008.

As Crossref explains in their guidelines, the original concise doi:10.1037/rmh0000008 format was recommended with the hope that web browsers would one day automatically recognize and hyperlink these DOIs.

Effective March 2017, Crossref, an influential DOI registration agency, now recommends the following format: https://doi.org/10.1037/rmh0000008 Note the use of “https” instead of “http”, and “doi.org” instead of “dx.doi.org”.

Questions Still have questions? Check the following FAQ entries, or, if these don’t answer your question, use the Zotero forums: Can I use Zotero in one language and create bibliographies in another? DOI format in APA style Does Zotero support label/authorship trigraph styles, like [ddb98]? How can subsequent occurences of the same author replaced by a fixed term/symbol? How do I prevent title casing of non-English titles in bibliographies? How do I use rich text formatting, like italics and sub/superscript, in titles? How do you cite a secondary source in Zotero? How does Zotero parse things in the name fields? I need to use Chicago style. Which of the three versions that come with Zotero should I use? I'm the publisher/editor of a journal. What can I do to have Zotero support our style? Journal Abbreviations Missing Italics (or Italics-Only) in Word Bibliographies References appear in the wrong font in Word/LibreOffice Standard Citation Styles What are these DOIs doing in my bibliography? What is the official Harvard style? Why do some citations include first names or initials, and how can I prevent this from happening? Why don't titles show up in sentence case in bibliographies? Why isn't the first letter of a subtitle in uppercase in bibliographies?

You can also install CSL styles (with a “.csl” extension) from local files on your computer (e.g., styles that you edit yourself or that you download from another website). In the Zotero Style Manager, click the '+' button, then find the style file on your computer.

Zotero currently uses the title, DOI, and ISBN fields to determine duplicates. If these fields match (or have no information entered), Zotero will also compare the years of publication and author/creator lists (if at least one author last name plus first initial matches) to determine duplicates.

Debug Output Logging: To help diagnose a problem, the Zotero developers may ask you to submit a Debug Log ID. This is different from an Error Report ID above. To submit a debug log, check “Enable Logging”, then complete the sequence of steps neeeded to produce your error. Then, click “Submit Debug Report” and post the Debug ID number to the Zotero forums. Try to avoid performing unrelated actions when making a debug log.

Automatic File Importing: By default, the Zotero Connector will offer to import RIS, BibTeX, and Refer/BibIX bibliographic files when you open them in your browswer. You can disable this feature or manage the sites from which data is imported here.

Save to Zotero.org: When the Zotero desktop client is closed, the Zotero Connector will save directly to the zotero.org servers. These settings let you reauthorize your broswer to save to your zotero.org account or clear your account credentials. You can also control whether PDF attachments and web page snapshots are automatically saved when importing to zotero.org.

the-solipsist commented on Mar 9, 2019 • edited Unfortunately, %g adds a ,, which doesn't work in those cases where there is not first name / surname (for instance, institutional authors). In those cases, %g ends up adding a comma in the end of the name. Additionally, %g provides a "Surname, Firstname" format, and there is no expression for "Firstname Surname", which some would prefer.

QingQYang commented on Aug 11, 2015 I have solved this problem by adding wildcard %g for author's full name as the style of Zotero's two fields display. Please check the pull request #193, thanks.

xyzzy21 12 days ago | prev | next [–] Scientific American started its decline in the 1990s. It became a "rag" in the 2000s. It's 100% worthless now. reply

duskwuff 13 days ago | parent | prev | next [–] The decline of Scientific American into pop science started much earlier than that. I'd peg it around 2000, when they changed the cover design and stopped running classic columns like "Mathematical Games" and "Amateur Scientist". The pop-science articles started ramping up around the same time. reply green01 12 days ago | root | parent | next [–] Same thing with Popular Science and Popular Mechanics, science reporting was the first to go in the death of journalism. They were terrible 15 years ago, maybe people didn't notice until recently when they started bizarrely endorsing politicians like Biden and running CRT articles.

cycomanic 13 days ago | prev | next [–] I always found the New Scientist a much better publication

Cthulhu_ 13 days ago | parent | next [–] I read a good article some time ago that explained the different 'levels' of scientific writing. Level 1 was the actual papers. Level 2 is the press releases of the university or research institute in question. And level 3 and beyond are the pop sci websites, magazines, social media channels etc picking up on it - and it becomes muddled after that, because they will often pick up and rewrite from each other instead of referencing the source.

Rama Says: Comment #111 January 5th, 2022 at 7:44 am Scientific American is no longer what it used to some decades back. The standard of articles has come down and has very low abysmal standards of written presentations. American Scientist (AS) has good content and would go for AS and ignore Scientific American.

The death of the Economist and Scientific American and the New Yorker are things the GOP mourns.

GregW Says: Comment #8 January 3rd, 2022 at 5:53 am Scientific American was really great in the 80s but somewhere in the 90s or early 2000s it took a turn towards dumbed down science popularism and lost my respect

the SciAm hit-piece, and then reported back to the others that the strong emotions were completely, 100% justified in this case.

Fortunately, there are high-quality online venues (e.g., Quanta) that partly fill the role that Scientific American abdicated.

Subject classes do not exist for some of the older archives in the Physics group. Instead, each archive represents a subject class, e.g., hep-ex, hep-lat, hep-ph, and hep-th. The astro-ph archive currently has no subject classes, while cond-mat and physics are classified by subject classes that appear only in the metadata (not in the identifier). This scheme uses two upper-case characters to identify the subject class,

The canonical form of identifiers from January 2015 (1501) is arXiv:YYMM.NNNNN, with 5-digits for the sequence number within the month. The article identifier scheme used by arXiv was changed in April 2007. All existing articles retain their original identifiers but newly announced articles have identifiers following the new scheme. As of January 2015, the number of digits used in the second part of the new identifier, the sequence number within the month, is increased from 4 to 5. This will allow arXiv to handle more than 9999 submissions per month (see monthly submission rates).

birnstiel commented on Mar 17, 2015 Thanks! The export script only returns the bibcodes, not the full entries. Is there a way to query all those bib codes? The ADS 2.0 search seems to support only one bibcode: search.

Search translators: can look up and retrieve item metadata when supplied with a standard identifier, like a PubMed ID (PMID) or DOI.

dataMode For import translators, this sets the form in which the input data is presented to the translator. If set to “rdf/xml”, Zotero will parse the input as XML and expose the data through the Zotero.RDF object. If “xml/dom”, Zotero will expose the data through the function Zotero.getXML().

browserSupport A string containing one or more of the letters g, c, s, i, representing the connectors that the translator can be run in – Gecko (Firefox), Chrome, Safari, Internet Explorer, respectively. b indicates support for the Bookmarklet (zotero-dev thread) and v indicates support for the translation-server. For more information, see Connectors. Warning: Compatible with Zotero 2.1.9 and later only.

translatorType An integer specifying to which type(s) the translator belongs. The value is the sum of the values assigned to each type: import (1), export (2), web (4) and search (8). E.g. the value of translatorType is 2 for an export translator, and 13 for a search/web/import translator, because 13=8+4+1.

although if you are using XMLDOM with JavaScript you can code something like var n1 = uXmlDoc.selectSingleNode("//bookstore/book[1]/title/@lang"); and n1.text will give you the value "eng"

@KorayTugay, No, the first expression selects, doesn't "return" -- a set of nodes, and this set of nodes is not a string. A node is not a string -- a node is a node in a tree. An XML document is a tree of nodes. lang="eng" is just one of many textual representations of an attribute node that has a name "lang", doesn't belong to a namespace, and has a string value the string "eng" – Dimitre Novatchev Oct 22 '14 at

//Parent[@id='1']/Children/child/@name will only output the name attribute of the 4 child nodes belonging to the Parent specified by its predicate [@id=1]. You'll then need to change the predicate to [@id=2] to get the set of child nodes for the next Parent. However, if you ignore the Parent node altogether and use: //child/@name you can select name attribute of all child nodes in one go.

//Parent[@id='1']/Children/child/@name Your original child[@name] means an element child which has an attribute name. You want child/@name.

So far I have this XPath string: //Parent[@id='1']/Children/child[@name]

shows the primary classification in a standard way, and is also recommended as the preferred citation format

Extension. The new scheme could be extended to use more than 4 or 5 digits for the sequence number. However, that would correspond to more than 99999 submissions per month, or over 10 times the current submission rate, and is thus not anticipated for many years.

Old papers in archives where the archive name matches the primary subject classification (e.g. hep-th) do not have the square brackets with primary subject classification

Many bibliography databases supply a DOI (Digital Object Identifier) or arXiv eprint number with BibTeX entries. However, the standard BiBTeX style files either ignore this information or print it without hyperlinking it correctly. Here’s how you can get working clickable links to both DOI and arXiv eprints.

For the new style arXiv identifiers (April 2007 and onwards) we recommend these bib-style extensions: **archivePrefix = "arXiv"**, **eprint = "0707.3168"**, **primaryClass = "hep-th"**,

adamsmith 20 days ago DOI: in extra works for citations. We'll get a preprint item type and DOI added to all item types, but in the meantime that'll just work

dmilton 20 days ago The problem with using "Report" type for preprints is that it does not keep the doi -- only if it is imported as a journal article does the doi get saved. Please add doi to the "Report" fields -- I find myself having to change to type "Journal Article" to perserve the doi.

When I said "migrated automatically", I was referring to the item becoming Zotero Preprint items when that type is added in the future.

bwiernik June 18, 2021 Zotero will get a Preprint type in an upcoming version. For now, the appropriate way to enter them is as a Report with this at the top of Extra:Type: articleThat will be migrated automatically to Preprint when the type is added.

stared June 18, 2021 This function is useful for numerous reasons. Primarily for listing preprints (e.g. arXiv, biorXiv) and PubMed codes.See "eprint" as officially listed in an arXiv instruction (https://arxiv.org/help/hypertex/bibstyles) and Getting DOI / arXiv links with BibTeX (https://www.math.cmu.edu/~gautam/sj/blog/20171114-bibtex-doi.html), as well as some older approaches e.g. mine for giving link to arXiv for Mendeley exports https://gist.github.com/stared/5473014.Yes, it is a pity that proprietary Mendeley owned by Elsevier provides better support for open archives.

emilianoeheyns September 27, 2020 Since Better BibLaTeX is already omitting Zotero's Publication field for arXiv preprints, it should probably export as '@misc' or '@online', not '@article'. That is a good point. Could you open an issue for it on BBTs github tracker? Therefore, a BBT postscript should better not depend on Publication being empty or on the presence of an arXiv ID If BBT detected an arXiv entry in any way you, in the postscript item will have an attribute item.arXiv which looks like { id: <arXiv ID>, category: <arXiv category, if found> }

adamsmith September 23, 2020 Here's the history on why we're importing arXiv preprints as journal articles:https://github.com/zotero/translators/issues/616If things has changed (e.g. if sites like ADS and INSPIRE are handling this differently now) we can change this on the import end of things, too, but it's really not so clear cut as to say it's wrong.

emilianoeheyns September 23, 2020 The bibtex entry recommended by arXiv for example, asks for preprint items to be @misc Where do they ask this? If this is how arXiv items should appear generally, I could adjust BBT to change the entry type. Right now, BBT will add the eprint fields if you either: Set the Library Catalog to arXiv or arXiv.org and the Journal name to the arXiv ID Add arXiv: <arXiv ID> to the extra field on a line of its own

adamsmith September 23, 2020 There will almost certainly be a Zotero preprint item type added the next time any item types are added. No ETA, but the hope is that this isn't too far off (i.e. months not years)

tdegeus November 2, 2021 +100 on this. It would be great though to simply have a field arxivid (that could be potentially activated on request). This would catch the case that the same article is on multiple preprint servers (which could happen I guess). dougwyu November 27, 2021 yes please add a preprint category. biologists use BioRXiv a lot!, and i have to hand-edit every downloaded article.

"Twist of Fate" is a song recorded by English-Australian singer Olivia Newton-John for the soundtrack album to the 1983 romantic fantasy comedy film, Two of a Kind. Written by Peter Beckett and Steve Kipner,[2] and produced by David Foster, the song was released as the first single from the album on 21 October 1983, and reached number four in Australia and Canada. It reached its peak position of number five on the US Billboard Hot 100 on January 1984, becoming Newton-John's last top-ten single on the chart to date. Billboard ranked "Twist of Fate" as the 42nd most popular single of 1984.

As a songwriter and producer, he worked with Olivia Newton-John from 1971 through 1989. He wrote her number-one hit singles: "Have You Never Been Mellow" (1975), "You're the One That I Want" (1978 duet with John Travolta), "Hopelessly Devoted to You" (1978), and "Magic" (1980). He also produced the majority of her recorded material during that time including her number-one albums, If You Love Me, Let Me Know (1974), Have You Never Been Mellow (1975), and Olivia's Greatest Hits Vol. 2 (1982). He was a co-producer of Grease (1978) – the soundtrack for the film Grease.

Producer(s)John Farrar

"Heart Attack" is a song recorded by English-born Australian singer Olivia Newton-John for her second greatest hits album Olivia's Greatest Hits Vol. 2 (1982). Written by Paul Bliss and Steve Kipner, and produced by John Farrar, the song was the first single released from the album and was nominated for a Grammy Award for Best Female Pop Vocal Performance in 1983.

APIs for Scholarly Resources What is an API? API stands for application programming interface. An API is a protocol that allows a user to query a resource and retrieve and download data in a machine-readable format.  Researchers sometimes use APIs to download collections of texts, such as scholarly journal articles, so they can perform automated text mining on the corpus they've downloaded. Here is a simple tutorial that explains what an API is.  Below are some APIs that are available to researchers. Some are open to the public, while others are available according to the terms of Temple University Libraries' subscriptions. Many require you to create an API key, which is a quick and free process.   How do I Use APIs? You can create a simple query in the address bar in a web browser. However, a more complex query generally requires using a programming language. Commonly used languages for querying APIs are Python and R. (R is the language used in the R software.) The examples given in the documentation for the APIs listed below typically do not include sample programming code; they only explain how the data is structured in order to help users write a query.

adamsmith May 8, 2018 I don't think that's possible for technical reasons at this time because the citekey is generated & stored by the BetterBibTeX extension and not Zotero itself. It's likely going to be possible in the future. bwiernik May 8, 2018 Yes, the BBT developer had to disable citekey searching because it was interfering with other parts of Zotero. You can show the citekey as a column in the center pane and sort on that.

the collections pane supports find-as-you-type, so if you want to switch to a given library or collection you can press Cmd-Shift-L/Ctrl-Shift-L to highlight the collections pane and then start typing the name of the library or collection to select it. (If a library was collapsed and you wanted to get to a collection, you'd need to type the name of the library and then press right-arrow or + to expand collections (depending on how nested the one you were looking for was) and then type the collection name.)

The old versions of JavaScript had no import, include, or require, so many different approaches to this problem have been developed. But since 2015 (ES6), JavaScript has had the ES6 modules standard to import modules in Node.js, which is also supported by most modern browsers. For compatibility with older browsers, build tools like Webpack and Rollup and/or transpilation tools like Babel can be used.

import La sentencia import se usa para importar funciones que han sido exportadas desde un módulo externo. Por el momento, esta característica sólo está comenzando a ser implementada de forma nativa en los navegadores. Está implementada en muchos transpiladores, tales como Typescript y Babel, y en empaquetadores como Rollup y Webpack.

Just last year Grunt was effectively dethroned by Gulp. And now, just as Gulp and Browserify are finally reaching critical mass, Webpack threatens to unseat them both. Is there truly a compelling reason to change your front-end build process yet again?

It's possible, but you have to be careful. Trying to require() a package means that node will try to locate its files in your file system. A chrome extension only has access to the files you declare in the manifest, not your filesystem. To get around this, use a module bundler like Webpack, which will generate a single javascript file containing all code for all packages included through require(). You will have to generate a separate module for each component of your chrome extension (e.g. one for the background page, one for content scripts, one for the popup) and declare each generated module in your manifest. To avoid trying to setup your build system to make using require() possible, I suggest starting with a boilerplate project. You can check out my extension to see how I do it.

Cómo añadir imágenes de fondo personalizadas en Microsoft Teams para Windows Solo hay que abrir el explorador de Windows y en la barra superior, introducir esta dirección: %AppData%\Microsoft\Teams\Backgrounds\Uploads En esa carpeta que se abre, no hay más que añadir todas las imágenes en formato JPG que quieras y listo.

3.1.1.1 Encoding an OAI-PMH request in a URL for an HTTP GET URLs for GET requests have keyword arguments appended to the base URL, separated from it by a question mark [?]. For example, the URL of a GetRecord request to a repository with base URL that is http://an.oa.org/OAI-script might be: http://an.oa.org/OAI-script? verb=GetRecord&identifier=oai:arXiv.org:hep-th/9901001&metadataPrefix=oai_dc However, since special characters in URIs must be encoded, the correct form of the above GET request URL is: http://an.oa.org/OAI-script? verb=GetRecord&identifier=oai%3AarXiv.org%3Ahep-th%2F9901001&metadataPrefix=oai_dc

doGet()/doPost() return raw text, which is useful for anything retrieving BibTeX/RIS/etc. It would be nice to be able to just do var ris = await request(url);.

IE will block appending any element created in a different window context from the window context that the element is being appending to. var childWindow = window.open('somepage.html'); //will throw the exception in IE childWindow.document.body.appendChild(document.createElement('div')); //will not throw exception in IE childWindow.document.body.appendChild(childWindow.document.createElement('div'));

The actual problem is that when the page is loaded with document.write, IE will always load inline javascript blocks before external javascript files, regardless of which one get defined first. This is described in dynamicdrive.com/forums/blog.php?bt=173 (section II). A good workaround is to put everything as external javascript files. – sayap Jan 5 '12 at 5:05

Qiqqa already has the option to overwrite the info in Qiqqa with any metadata that is in the import file. And it avoids duplicate PDF records.

I would be more than happy to add an importer into Qiqqa from Zotero. I guess the simplest route could be to augment the zotero bibtex output format to include any attached files (much like Mendeley does in the file={} field).

jamesjardine July 11, 2010 Hiya,It's Jimme here. I am the guy building Qiqqa.

Automatic export To export a library, group or collection, right-click on it in the left Zotero pane and choose “Export Library…” or “Export Collection…”. With BBT’s export translators (e.g., “Better BibTeX”), checking the Keep updated option will register the export for automation. After you’ve completed the current export, any changes to the collection or library will trigger an automatic re-export to update the file. You can review/remove exports from the BBT preferences. While I’ve gone to some lengths to make sure performance is OK, don’t go overboard with the number of auto-exports you have going. Also, exporting only targeted selections over your whole library will get you better performance. You can set up separate exports for separate papers for example if you have set up a collection for each. Managing auto-exports After you’ve set up an auto-export using an Keep updated export, you can manage your auto-exports in the BBT preferences under the Automatic exports tab. There, you can remove auto-export, change settings on them, or remove them. You cannot add new auto-exports from here, that can only be done by initiating an export.

dstillman April 22, 2020 Yes, CSL-JSON is specifically for citations and doesn't know anything about attachments. emilianoeheyns April 23, 2020 BBT JSON does know about attachments. It's mostly just a dump of the items as they're handed to translators with cleanup. I use it in my test framework, but when BBT is installed it's available as any other import/export format.

jwright8 August 19, 2018 adamsmith, I added Zutilo to Zotero stand alone (I am not using Firefox). I was able to find the location of my attachments by right clicking on items > Zutilo > Show Attachment Paths. Now I need to do the batch change or follow dstillman's instructions: "set up a Linked Attachment Base Directory in the Advanced → Files and Folders pane of the Zotero preferences, move the directory, and then update the base directory."

Have a look at the Zutilo add-on, which can show you the current path Zotero is looking and also batch-change those paths.https://github.com/willsALMANJ/Zutilo

It's funny: I'm always teaching new electronic research tools, I've turned my students on to Zotero but beyond a very short paper, they (and I) still return to index cards!! This would be a killer app.

adamsmith May 19, 2013 So, the argument for the status quo is that the working paper on arxiv is a separate publication from the journal article it ends up published as. That's why it should be saved and - where it applies - cited differently. In other words, taking bibliographic data seriously, the DOI does _not_ apply to the arxiv paper and should not be saved with it. That's in line with what we do with other working paper repositories such as SSRN.

aurimas May 19, 2013 Looks like that was an intentional decision to put arXiv identifier in the publication field

karnesky commented on Sep 1, 2013 A few things to note here: arXiv does have preprints, but a lot of these are linked to journal articles & some people use it as a reprint server. If an arXiv record has a DOI, I would suggest (strongly) that it should be typed as a journal article. We may even just use the ADS link, which seems to have a great BibTeX-formatted record for most eprints (though I'm torn on doing that). NASA ADS and most others classify arXiv eprints as journal articles anyway. Zotero will import any of those as journal articles, so there might be a case to import all arXiv eprints as if they were journal articles

If/when we have a proper field for arXiv IDs in Zotero (which I believe has a very good chance of happening), we can handle this a lot more elegantly, of course, both on import and on export.

adamsmith November 17, 2013 The problem is that Zotero isn't just a bib(la)tex front-end and those field mappings don't make a huge amount of sense in Zotero - Archive and Loc. in Archive are at least somewhat plausible (Call number makes no sense),

However these fields are not filled automatically by zotero when importing from arxiv, instead a Report is created with all three fields (Archive, Loc. in Archive, Call number) empty

Further, by trial and error I found that setting the Journal article fields as follows: Archive: arxiv Loc. in Archive: 1234.1231 Call number: hep-ph results in zotero exporting a biblatex file containing: eprinttype = {arxiv}, eprint = {1234.1231}, eprintclass = {hep-ph},

According to the biblatex manual ftp://bay.uchicago.edu/CTAN/macros/latex/exptl/biblatex/doc/biblatex.pdf section 3.11.7, arxivprefix is an alias for eprinttype and primaryclass is an alias for eprintclass.

I don't see how we can support the bibtex extension fields (archivePrefix and primaryClass)

I see that the field "Loc. in Arxive" is already exported as "eprint" when using BibLatex

uses in general the fields archivePrefix, eprint and primaryClass

The recommended way to add arxiv information to bibtex items is giving here http://arxiv.org/hypertex/bibstyles/

Zotero.configure() and Zotero.displayOptions() replaced by configOptions and displayOptions Zotero.configure() and Zotero.displayOptions() no longer exist. Instead, translators should specify config and display options in the metadata block at the top of the translator, e.g. { "translatorID":"32d59d2d-b65a-4da4-b0a3-bdd3cfb979e7", [...] "configOptions":{"dataMode":"rdf/xml"}, "displayOptions":{"exportNotes":true}, "lastUpdated":"2011-01-11 04:31:00" } "dataMode":"block" and "dataMode":"line" are deprecated It is no longer necessary to specify “dataMode”:“block” or “dataMode”:“line”. If Zotero.read() is passed a numeric value, it reads a specified number of bytes; otherwise, it reads a full line.

translator.setSearch(item) For search translators. Sets the skeleton item object the translator will use for its search. translator.setString(string) For import translators. Sets the string that the translator will import from. translator.setDocument(document) For web translators. Sets the document that the translator will use.

record.leader = "leader goes here"; record.addField(code, indicator, content);

Calling a translator using ''getTranslators'' This code, based on the “COinS.js” code, calls getTranslators() to identify which search translators can make a complete item out of the basic template information already present. Note that translate() is called from within the event handler. Analogous logic could be used to get the right import translator for incoming metadata in an unknown format. var search = Zotero.loadTranslator("search"); search.setHandler("translators", function(obj, translators) { search.setTranslator(translators); search.translate(); }); search.setSearch(item); // look for translators for given item search.getTranslators();

Calling a translator by UUID This is the most common way to use another translator– simply specify the translator type and the UUID of the desired translator. In this case, the RIS translator is being called. var translator = Zotero.loadTranslator("import"); translator.setTranslator("32d59d2d-b65a-4da4-b0a3-bdd3cfb979e7"); translator.setString(text); translator.translate();

Calling other translators Web translators can call other translators to parse metadata provided in a standard format with the help of existing import translators, or to augment incomplete data with the help of search translators. There are several ways of invoking other translators.

Batch Saving You will often need to make additional requests to fetch all the metadata needed, either to make multiple items, or to get additional information on a single item. The most common and reliable way to make such requests is with the utility functions Zotero.Utilities.doGet, Zotero.Utilities.doPost, and Zotero.Utilities.processDocuments. Zotero.Utilities.doGet(url, callback, onDone, charset) sends a GET request to the specified URL or to each in an array of URLs, and then calls function callback with three arguments: response string, response object, and the URL. This function is frequently used to fetch standard representations of items in formats like RIS and BibTeX. The function onDone is called when the input URLs have all been processed. The optional charset argument forces the response to be interpreted in the specified character set. Zotero.Utilities.doPost(url, postdata, callback, headers, charset) sends a POST request to the specified URL (not an array), with the POST string defined in postdata and headers set as defined in headers associative array (optional), and then calls function callback with two arguments: response string, and the response object. The optional charset argument forces the response to be interpreted in the specified character set. Zotero.Utilities.processDocuments(url, callback, onDone, charset) sends a GET request to the specified URL or to each in an array of URLs, and then calls the function callback with a single argument, the DOM document object. Note: The response objects passed to the callbacks above are described in detail in the MDC Documentation. Zotero.Utilities.processAsync(sets, callbacks, onDone) can be used from translators to make it easier to correctly chain sets of asynchronous callbacks, since many translators that require multiple callbacks do it incorrectly [text from commit message, r4262]

for each item, an item ID and label should be stored in the object as a property/value pair.

Passing the object to the Zotero.selectItems function will trigger the selection window, and the function passed as the second argument will receive an object with the selected items, as in this example: Zotero.selectItems(getSearchResults(doc, false), function (items) { if (!items) return; ZU.processDocuments(Object.keys(items), scrape); }); Here, Zotero.selectItems(..) is called with an anonymous function as the callback. As in many translators, the selected items are simply loaded into an array and passed off to a processing function that makes requests for each of them.

Saving Multiple Items Some webpages, such as those showing search results or the index of a journal issue, list multiple items. For these pages, web translators can be written to a) allow the user to select one or more items and b) batch save the selected items to the user's Zotero library. Item Selection To present the user with a selection window that shows all the items that have been found on the webpage, a JavaScript object should be created. Then, for each item, an item ID and label should be stored in the object as a property/value pair. The item ID is used internally by the translator, and can be a URL, DOI, or any other identifier, whereas the label is shown to the user (this will usually be the item's title). Passing the object to the Zotero.selectItems function will trigger the selection window, and the function passed as the second argument will receive an object with the selected items, as in this example: Zotero.selectItems(getSearchResults(doc, false), function (items) { if (!items) return; ZU.processDocuments(Object.keys(items), scrape); }); Here, Zotero.selectItems(..) is called with an anonymous function as the callback. As in many translators, the selected items are simply loaded into an array and passed off to a processing function that makes requests for each of them. Batch Saving You will often need to make additional requests to fetch all the metadata needed, either to make multiple items, or to get additional information on a single item. The most common and reliable way to make such requests is with the utility functions Zotero.Utilities.doGet, Zotero.Utilities.doPost, and Zotero.Utilities.processDocuments. Zotero.Utilities.doGet(url, callback, onDone, charset) sends a GET request to the specified URL or to each in an array of URLs, and then calls function callback with three arguments: response string, response object, and the URL. This function is frequently used to fetch standard representations of items in formats like RIS and BibTeX. The function onDone is called when the input URLs have all been processed. The optional charset argument forces the response to be interpreted in the specified character set. Zotero.Utilities.doPost(url, postdata, callback, headers, charset) sends a POST request to the specified URL (not an array), with the POST string defined in postdata and headers set as defined in headers associative array (optional), and then calls function callback with two arguments: response string, and the response object. The optional charset argument forces the response to be interpreted in the specified character set. Zotero.Utilities.processDocuments(url, callback, onDone, charset) sends a GET request to the specified URL or to each in an array of URLs, and then calls the function callback with a single argument, the DOM document object. Note: The response objects passed to the callbacks above are described in detail in the MDC Documentation. Zotero.Utilities.processAsync(sets, callbacks, onDone) can be used from translators to make it easier to correctly chain sets of asynchronous callbacks, since many translators that require multiple callbacks do it incorrectly [text from commit message, r4262]

Notes Notes are saved similarly to attachments. The content of the note, which should consist of a string, should be stored in the note property of the item's notes property. E.g.: let bbCite = "Bluebook citation: " + bbCite + "."; newItem.notes.push({ note: bbCite });

Zotero will automatically use proxied versions of attachment URLs returned from translators when the original page was proxied, which allows translators to construct and return attachment URLs without needing to know whether proxying is in use. However, some sites expect unproxied PDF URLs at all times, causing PDF downloads to potentially fail if requested via a proxy. If a PDF URL is extracted directly from the page, it's already a functioning link that's proxied or not as appropriate, and a translator should include proxy: false in the attachment metadata to indicate that further proxying should not be performed:

In the very common case of saving the current page as an attachment, set document to the current document, so that Zotero doesn't have to make an additional request: newItem.attachments.push({ title: "Snapshot", document: doc });

scrape[edit] The scrape function is called to save a single item. It is the most interesting function to code in a translator. We first create a new item as returned by detectWeb and then store the metadata in the relevant fields of that item. Along with the metadata, attachments can be saved for an item. These attachments become available even when one is offline. In the function shown below, we make use of another translator called Embedded Metadata. We load this translator and it scrapes information from the meta tags of the web page, filling fields and reducing our work. We can always insert and update information of fields on top of what Embedded Metadata provided.function scrape(doc, url) { var translator = Zotero.loadTranslator('web'); // Embedded Metadata translator.setTranslator('951c027d-74ac-47d4-a107-9c3069ab7b48'); translator.setDocument(doc); translator.setHandler('itemDone', function (obj, item) { // Add data for fields that are not covered by Embedded Metadata item.section = "News"; // Add custom fields if required trans.addCustomFields({ 'twitter:description': 'abstractNote' }); item.complete(); }); translator.getTranslatorObject(function(trans) { // Adjust for multiple item types trans.itemType = "newspaperArticle"; trans.doWeb(doc, url); }); }

Zotero.selectItems(getSearchResults(doc, false), function (items) { if (!items) { return true; } var articles = []; for (var i in items) { articles.push(i); } ZU.processDocuments(articles, scrape);

Generate test cases[edit] Once the code of a translator is prepared, it is recommended to create test cases. These test cases are run daily and help the community to figure out if a translator fails in future and needs any update or complete rewriting. We will generate test cases for MediaWiki translator through Scaffold. Open mediawiki in a new tab. Launch Scaffold and open the translator we have created. Open the "Testing" tab of Scaffold. We need to give a web page as input. For example, open citoid's page. Keeping this web page as the active tab, simply click on the "New Web" button. It will load the web page in the Input pane as a new unsaved test. Select the input entry and click the save button to have the output of test be saved as JSON data. Similarly lets create a test case for a search page. Open this link in a new tab as the active one and then click on "New Web". Once it is loaded, save it. You can see the saved test cases in the "Test" tab of Scaffold. For this search page, you can notice a JSON object as follows.var testCases = [ { "type": "web", "url": "https://www.mediawiki.org/w/index.php?search=Zotero+&title=Special:Search&go=Go&searchToken=2pwkmi9qkwlogcnknozyzpco1", "items": "multiple" } ]

Generate testCases (with Scaffold).

An overview of the currently installed translators, giving the option of running their tests, can be accessed by entering the following into the address bar: chrome://zotero/content/tools/testTranslators/testTranslators.html

In most cases, it is not necessary or desirable to write these tests by hand– they can and should be generated by the testing framework using Scaffold; see below.

htmlSpecialChars Function description https://www.zotero.org/trac/browser/extension/branches/1.0/chrome/content/zotero/xpcom/utilities.js#L153 Zotero.Utilities.prototype.htmlSpecialChars = function(str) @type String Escapes several predefined characters: & (ampersand) becomes &amp; “ (double quote) becomes &quot; ' (single quote) becomes &#039; < (less than) becomes &lt; > (greater than) becomes &gt; and <ZOTEROBREAK/> becomes <br/> <ZOTEROHELLIP> becomes &#8230;

parseMarkup Function description https://www.zotero.org/trac/browser/extension/branches/1.0/chrome/content/zotero/xpcom/utilities.js#L206 Zotero.Utilities.prototype.parseMarkup = function(str) @return {Array} An array of objects with the following form: { type: 'text'|'link', text: “text content”, [ attributes: { key1: val [ , key2: val, …] } }</pre> Parses a text string for HTML/XUL markup and returns an array of parts. Currently only finds HTML links (<a> tags)

Zotero.Translate/translators Added Zotero.Utilities.processAsync(sets, callbacks, onDone) – this can be used to make it easier to correctly chain sets of asynchronous callbacks

The functions Zotero.Utilities.HTTP.doGet and Zotero.Utilities.processDocuments run asynchronously. In order to allow them to complete before moving along, follow either function with Zotero.wait() and include Zotero.done() as the onDone in order to signal the translator that it has completed its asynchronous operations.
