Mr. Wittenburg started by thanking the Executive Director who had provided useful inputs relating to EOSCdiscussions in Western Europe. In Mr. Wittenburg's view the DO Architecture technology was now facingtwo main challenges: (i) building such infrastructure was taking more time than it had initially beenexpected; and (ii) building such infrastructure was still a highly dynamic issue as there were many differentsuggestions and positions among the players. For Mr. Wittenburg, a DONA strength was that it was an islandof stability in this dynamic environment

In a journal article or manuscript a sample identified by IGSN SSH000SUA may look like this (tagged IGSN): IGSN:SSH000SUA

Unlike many other persistent identifiers, an IGSN is used not only used by machines but also needs to be handled by humans.

DOIs have a business model. LSIDs currently do not. Without a business model (read funding) we should stick to something that doesn’t have the implementation/adoption impediment of LSIDs and make the best of it (i.e. just have a usage policy for HTTP URIs).

Without some kind of persistence mechanism the only advantage of LSIDs is that they look like they are supposed to be persistent. Unfortunately, because many people are using UUIDs as their object identifiers LSIDs actually look like something you wouldn’t want to look at let alone expose to a user! CoL actually hide them because they look like this: urn:lsid:catalogueoflife.org:taxon:d755ba3e-29c1-102b-9a4a-00304854f820:ac2009

The act of minting an LSID indicates that you intend to try to make it permanent or at least never re-use it for another resource.

The preferred PID scheme In consideration of the foregoing, the strongest option across the studied major dimensions of the available Handle System PID schemes and operational modes is for DiSSCo to use DOIs to identify Digital Specimens. The case for choosing DOI comes out slightly more strongly than choosing ePIC for reasons related to the substantial achievements, operational experience and reputation of DOI/ IDF to date. Operating under another Handle-system prefix than those used by IDF and ePIC is the substantially weakest option because of the difficulties associated with introducing an identifier that is not perceived to be a DOI. The term ‘DOI’ is trademarked by the IDF and thus not available for describing other identifiers. The practical and sensible avenue to explore further are the options to establish and become an RA member of the DOI Foundation (option A5) and to enter a strategic alliance at the level of the DOI Foundation (option A1). These options are likely most effective when actioned in combination.

When digitized, each resulting ‘Digital Specimen’ must be persistently and unambiguously identified. Subsequent events or transactions associated with the Digital Specimen, such as annotation and/or modification by a scientist must be recorded, stored and also unambiguously identified.

Persistent identifiers (PID) to identify digital representations of physical specimens in natural science collections (i.e., digital specimens) unambiguously and uniquely on the Internet are one of the mechanisms for digitally transforming collections-based science.

Information quality is the strongest factor to influence organizational benefits through perceived usefulness and user satisfaction

Which identifiers are FAIR enough?

digital or physical objects, or concepts

Compact identifiers are a longstanding informal convention in bioinformatics. To be used as globally unique, persistent, web-resolvable identifiers, they require a commonly agreed namespace registry with maintenance rules and clear governance; a set of redirection rules for converting namespace prefixes, provider codes and local identifiers to resolution URLs; and deployed production-quality resolvers with long-term sustainability.

Breaking of links is mostly due to administrative changes at the referencedInternet node

Over time the risk grows that the document is no longer accessible at the loca-tion given as reference. Web servers that follow the HTTP protocol then givethe notorious reply: ‘404 not found’. This resembles the situation of a book in a– very large – library that is not on the shelf at the position indicated in the cata-logue. How is it to be found?

In the mid 1990s, a number of schemes were developed that, rather than rely-ing on the precise address of a document, introduced the idea of name spaces forrecording the names and locations of documents.

Archives. The Member shall use best efforts to contract with a third-party archive or other content host (an "Archive") (a list of which can be found here) for such Archive to preserve the Member's Content and, in the event that the Member ceases to host the Member's Content, to make such Content available for persistent linking.

Maintaining and Updating Metadata.

ePIC PID service, and an organisation, that provides a PID service and is not an ePIC member, can ask for a certification, that it provides its PID service along the lines of the ePIC rules and policies.

ePIC has rules and policies, how to provide PID services and how to ensure the reliability, that is necessary for the persistency of access to digital objects via ePIC PIDs.

Registered production PIDs will not be deleted. They are used as a kind of tombstone even if the underlying data is not available anymore.

Persistent identifiers (PIDs) are an abstraction layer that arbitrates between the reference of a digital object and its location.

Scalability – in the data/metadata stored;

ORCID was first announced in 2009

The developer and administrator of the DOI system is the International DOI Foundation (IDF), which introduced it in 2000

5.2. Key ? was(DESCRIPTION) when(DATE) resync This "metadata" command form provides nothing more than a way to carry a Key along with its description. The form is a "no-op" (except when "resync" is present) in the sense that the Key is treated as an adorned URL (as if no THUMP request were present). This form is designed as a passive data structrue that pairs a hyperlink with its metadata so that a formatted description might be surfaced by a client-side trigger event such as a "mouse-over". It is passive in the sense that selecting ("clicking on") the URL should result in ordinary access via the Key-as-pure-link as if no THUMP request were present. The form is effectively a metadata cache, and the DATE of last extraction tells how fresh it is. The "was" pseudo-command takes multiple arguments separated by "|", the first argument identifying the kind of DESCRIPTION that follows, e.g,

To resolve a Compact ARK (ie, an ARK beginning "ark:") it must initially be promoted to a Mapping ARK so that it becomes actionable. On the web, this means finding a suitable web Resolver Service to prepend to the compact form of the identifier in order to convert it to a URL (cf [CURIE]). (This is more or less true for any type of identifier not already in URL form.)

When content underlying a DOI is updated, we recommend updating the DOI metadata and, for major changes, assigning a new DOI. For minor content changes, the same DOI may be used with updated metadata. A new DOI is not required. For major content changes, we recommend assigning a new DOI and linking the new DOI to the previous DOI with related identifiers.

To enable easy usability for both humans and machines, a DOI should resolve to a landing page that contains information about the DOI being resolved. It is the responsibility of the entity creating the DOI to provide such a landing page. The following are best practices for creating well-formed DOI landing pages.

there may be infrequent cases where it is not desirable for the item described by a DOI to be available publicly, such as in the case of research retraction. In these cases, it is best practice to still provide a "tombstone page", which is a special type of landing page describing the item that has been removed.

certification: If certified, acronym for certification organization or standard (e.g., TRAC, TDR, DSA) and year of certification.

succession: The plan for dealing with sudden loss of provider viability, including set-aside funding and length of time that operations would be able to support continued operation while a successor provider is found to keep references intact.

mission: One sentence mission statement of the organization.

business model: For profit (FP) or not for profit (NP).

name: Full name of the provider organization. identifier: Unique identifier for the organization.

check character (CC): A check character is incorporated in the assigned identifier to guard against common transcription errors.

inflection: a change to the ending of an object’s id string in order to obtain a reference to content related to the originally referenced content.

landing: content intended mostly for human consumption, such as an object description and links to primary information (e.g., an image file or a spreadsheet), to alternate versions and formats, and to related information; from “landing page”, this is intended to support a browsing experience of an abstract overall view of the object.

plunging: content intended as primary object information, often required or directly usable by software; from “below the landing page”, this is intended to support an immersive object experience that bypasses any browsing step.

introversioned: a kind of intraversioned content for which the version identifier (within the object identifier) is opaque, e.g., “http://doi.org/10.2345/678”, which happens to be version 4.

intraversioned: a version identifier is part of the id string, e.g., “http://doi.org/10.2345/67.V4”.

extraversioned: a version identifier is separate from the id string, so that the actionable id does not lead to specific version without human intervention, e.g., “http://doi.org/10.2345/67”, Version 4.

Precisely when such assignment will be triggered depends on policy that will differ across objects, collections, and providers.

waxing: change that is limited to appending content in a way that does not in itself disrupt or displace previously recorded content. Examples of waxing objects include live sensor-based data feeds, citation databases, and serial publications.

subinfinite: due to succession arrangements, the object is expected to be available beyond the provider organization’s lifetime.

lifetime: the object is expected to be available as long as the provider exists.

indefinite: the provider has no particular commitment to the object.

finite: availability is expected to end on or around a given date (e.g., limited support for software versions not marked “long term stable”) or trigger event (e.g., single-use link).

finite: availability is expected to end on or around a given date (e.g., limited support for software versions not marked “long term stable”) or trigger event (e.g., single-use link). indefinite: the provider has no particular commitment to the object. lifetime: the object is expected to be available as long as the provider exists. subinfinite: due to succession arrangements, the object is expected to be available beyond the provider organization’s lifetime.

We define content variance to be a description of the ways in which provider policy or practice anticipates how an object’s content will change over time. Approaches to content variance differ depending on the object, version, service, and provider.

molting: Previously recorded content may be entirely overwritten at any time with content that preserves thematic continuity. For example, an organization’s homepage may be completely reworked while continuing to be its homepage, and a weather or financial service page may reflect dramatic changes in conditions several times a day.

rising: Previously recorded content may be improved at any time, for example, with better metadata (datasets), new features (software), or new insights (pre- and post-prints). This encompasses any change under “fixing”

fixing: Previously recorded content may be corrected at any time, in addition to any change under “keeping”

keeping: Previously recorded content will not change, but character, compression, and markup encodings may change during a format migration, and high-priority security concerns will be acted upon (e.g., software virus decontamination, security patching).

frozen: The bit stream representing previously recorded content will not change

id string: the sequence of characters that is the identifier string itself, possibly modified by adding a well-known prefix (often starting with http://) in order to turn it into a URL. identifier: an association between an id string and a thing; e.g., an identifier “breaks” when the association breaks, but to act on an identifier requires its id string. actionable identifier: an identifier whose id string may be acted upon by widely available software systems such as web browsers; e.g., URLs are actionable identifiers.

On the other hand, the universal numeric fingerprint (Altman & King 2007) is a PID that supports citation of numeric data in a way that is largely immune to the syntactic formatting and packaging of the data

By contrast, repositories such as figshare (figshare 2016) and Merritt (Abrams et al. 2011) tolerate changes to metadata under the PID assigned originally, but create a new “versioned” PID if the object title or a component file changes, and in the latter case, the original non-versioned PID always references the latest version

The DataONE federated data network (Michener et al. 2011) assigns a PID to immutable data objects and a “series identifier” that resolves to the latest version of an object (DataONE 2015).

At a minimum it implies a prediction about an archive’s commitment and capacity to provide some specific kind of long-term functionality

persistence is purely a matter of service

We propose a novel approach relying on persistent, timestamped, adapted queries to versioned and timestamped data sources

Datafiles can be published with a suitable embargo period, forinstance to allow completion of publications or research basedon the dataset, or to respect contracts made by the depositorwith third parties concerning intellectual property rights.DANS encourages embargo periods of 6 months or less.

If a published dataset is improved by amendments to thedata files of the dataset, a major version increment iscreated with a record of changes. In cases where it isnecessary to disable access to earlier versions, these can bedeaccessioned

Data Management: Provenance, Versioning, and ReliableIdentification

Once a DOI is registered in the DOI System server, or repository, it will be stored there virtually forever.

median lifespan of these web pages was 9.3 years

Content drift describes the case where the resource identified by its URI changes over time and hence, as time goes by, the request returns content that becomes less and less representative of what was originally referenced.

The Handle System was first implemented in autumn 1994, and was administered and operated by CNRI until December 2015, when a new "multi-primary administrator" (MPA) mode of operation was introduced

These findings provide strong indicators that scholarly contentproviders reply to DOI requests differently, depending on the request method,the originating network environment, and institutional subscription levels

In addition, PIDs may be local to an individual organization (e.g. identifiers in an internal human resources system), national (e.g. the DAI – Digital Author Identifier, used in the Netherlands), or global (all the examples in the paragraph above).

identifiers for research objects and outputs, for example, DOIs (digital object identifiers), Archival Resource Key identifiers (ARKs), handles and IGSNs (International Geo Sample Number).

identifiers for organizations, including GRID (Global Research Identifier Database), Ringgold IDs, ISNIs (International Standard Name Identifiers), LEIs (legal entity identifiers) and the identifiers that will be provided by the recently announced Research Organization Registry2

identifiers for researchers, such as ORCID iDs, ResearcherIDs and Scopus IDs

Reasons to use ARK

To keep costs down. While some ARK service providers exist, ARKs can be implemented locally with open-source tools.

2 287 852

ARK systems such as Noid and N2T can record and provide metadata about any resource with an ARK.  That metadata becomes available via APIs, and can be seen when you add “?” to the end of an ARK URL. (See “Inflections” below) ARK metadata is very flexible, with no initial required metadata, but with support for multiple metadata schemas.  This flexibility is intentional: ARKs are designed to support a full digital object workflow, including the earliest stages before a resource is well-understood or described.

The ARK Alliance maintains a complete registry of all assigned NAANs, currently at the California Digital Library. The registry is mirrored at the (U.S.) National Library of Medicine and the National Library of France.

stakeholders

PIDs are exemplary implementations of FAIR data in their own right, but they also help to provide FAIR access to research entities like articles and datasets.

DOIs are a great solution for the problem of URIs that change over time, but this approach does depend on journal publishers, repositories, libraries, and other major hosting organization to be responsible for maintaining current link information within the DOI records that they have created

Ultimately the knowledge graph will permit a much clearer understanding of global research networks, research impact, and the ways in which knowledge is created in a highly interconnected world.

PIDs infrastructure promises much more accurate and timely reporting for key metrics including the number of publications produced at an institution in a given year, the total number of grants, and the amount of grant funding received.

They can also much more easily see whether researchers have met mandated obligations for open access publishing and open data sharing.

The global knowledge graph created by the interlinking of PIDs can help funders to much more easily identify the publications, patents, collaborations, and open knowledge resources that are generated through their various granting programs.

Although the DOIs assigned to relatively large aggregations of datasets are well suited for citation and acknowledgment pur-poses, they are not issued at fine enough granularity to meet the scientific imperative that published results should be traceableand verifiable

Persistent identifiers for acknowledgment and citation

ne key element is to generate a dataset-centric rather than system-centric focus, with an aim to making the infrastructure less prone to systemic failure.

scientific reproducibility and accountability

To reuse and/or reproduce research it is desirable that researchoutput be available with sufficient context and details for bothhumans and machines to be able to interpret the data as described inthe FAIR principles

Registration of research output is necessary to report tofunders like NWO, ZonMW, SIA, etc. for monitoring andevaluation of research (e.g. according to SEP or BKOprotocols). Persistent identifiers can be applied to ease theadministrative burden. This results in better reporting,better information management and in the end betterresearch information.

Epidemiologist Michael Abramson, who led the research, found that the participants who texted more often tended to work faster but score lower on the tests.

An AI model taught to view racist language as normal is obviously bad. The researchers, though, point out a couple of more subtle problems. One is that shifts in language play an important role in social change; the MeToo and Black Lives Matter movements, for example, have tried to establish a new anti-sexist and anti-racist vocabulary. An AI model trained on vast swaths of the internet won’t be attuned to the nuances of this vocabulary and won’t produce or interpret language in line with these new cultural norms. It will also fail to capture the language and the norms of countries and peoples that have less access to the internet and thus a smaller linguistic footprint online. The result is that AI-generated language will be homogenized, reflecting the practices of the richest countries and communities.

According to him, there are several goals connected to AI alignment that need to be addressed:

Actors: Language models could drive down the cost of running influence operations, placing them within reach of new actors and actor types. Likewise, propagandists-for-hire that automate production of text may gain new competitive advantages.Behavior: Influence operations with language models will become easier to scale, and tactics that are currently expensive (e.g., generating personalized content) may become cheaper. Language models may also enable new tactics to emerge—like real-time content generation in chatbots.Content: Text creation tools powered by language models may generate more impactful or persuasive messaging compared to propagandists, especially those who lack requisite linguistic or cultural knowledge of their target. They may also make influence operations less discoverable, since they repeatedly create new content without needing to resort to copy-pasting and other noticeable time-saving behaviors.

Editable metadata – identifiers’ metadata must be able to be edited in order to allow their owners to update details of the thing they are referring to, such as its location, as they will inevitably change.

Ownership – identifiers created must be able to have their management restricted to particular agent;

articulates requirements for readability sating that identifiers must be: Any printable characters from the Universal Character Set of ISO/IEC 10646 (ISO 2012):UTF-8 encoding is required; Case insensitive:Only ASCII case folding is allowed.

The reason for broadening them is that identifier resolution systems may be forced to change protocols over time and what is acceptable for one protocol may not be for another.

Creating identifiers that are independent of any particular technology or organisation and are able to be unambiguously understood are well-known requirement for PID systems.

Uniqueness – within some scope, not necessarily globally, to avoid clashes;

In addition, data model policy requires that RAs maintain a record of the date of allocation of a DOI name, and the identity of the registrant on whose behalf the DOI name was allocated.

The policy provides a simple test of an RA’s competence: the ability to make a DOI Kernel Declaration, which requires that the RA has an internal system which can support the unambiguous allocation of a DOI name, and is fundamentally sound enough to support interoperability within the network.

The second aim of DOI data model policy is “to ensure minimum standards of quality of administration of DOI names by Registration Agencies, and facilitate the administration of the DOI system as a whole”.

Registration Agencies must comply with the policies and technical standards established by the IDF, but are free to develop their own business model for running their businesses. There is no appropriate “one size fits all” model; RAs may be for-profit or not-for-profit organisations. The costs of providing DOI registration may be included in the services offered by an RA provision and not separately distinguished from these. Examples of possible business models may involve explicit charging based on the number of prefixes allocated or the number of DOI names allocated; volume discounts, usage discounts, stepped charges, or any mix of these; indirect charging through inclusion of the basic registration functions in related value added services; and cross-subsidy from other sources.

URNs are globally unique persistent identifiers assigned within defined namespaces so they will be available for a long period of time, even after the resource which they identify ceases to exist or becomes unavailable.

Approximately sixty formal URN namespace identifiers have been registered.

In order to ensure the global uniqueness of URN namespaces, their identifiers (NIDs) are required to be registered with the IANA. Registered namespaces may be "formal" or "informal".

A Uniform Resource Name (URN) is a Uniform Resource Identifier (URI) that uses the urn scheme. URNs are globally unique persistent identifiers assigned within defined namespaces so they will be available for a long period of time, even after the resource which they identify ceases to exist or becomes unavailable
