    1. The RDF model encodes data in the form ofsubject,predicate,objecttriples. The subjectand object of a triple are both URIs that each identify a resource, or a URI and a stringliteral respectively. The predicate specifies how the subject and object are related, and isalso represented by a URI.

    1. edges represent the named link between two resources

      The "triple"

    1. This document describes a vocabulary for annotating descriptions of vocabularies with examples and usage notes.
    1. Relevant vocabularies A combination of some W3C and third-party vocabularies can be used to formally capture the Technical Reports metadata in RDF. The following list summarizes these vocabularies: Event-based model of the W3C process Online documentation: http://www.w3.org/2001/02pd/rec54 Namespace: http://www.w3.org/2001/02pd/rec54# Ontology of the W3C organizational structure Namespace: http://www.w3.org/2001/04/roadmap/org# Vocabulary to annotate W3C TR with regard to Quality Assurance Online documentation: http://www.w3.org/2002/05/matrix/vocab Namespace: http://www.w3.org/2002/05/matrix/vocab# Vocabulary to describe document relationships and licenses Namespace: http://www.w3.org/2000/10/swap/pim/doc# Vocabulary for contact information Namespace: http://www.w3.org/2000/10/swap/pim/contact# Dublin Core Metadata Terms Online documentation: http://dublincore.org/documents/dcmi-terms/ Namespace: http://purl.org/dc/terms/ Note that some of these vocabularies are published by W3C, but they have no formal standing (they are not W3C Recommendations). In the following, it is assumed that the following namespace aliases are defined: Prefix Namespace rec: http://www.w3.org/2001/02pd/rec54# org: http://www.w3.org/2001/04/roadmap/org# mat: http://www.w3.org/2002/05/matrix/vocab# doc: http://www.w3.org/2000/10/swap/pim/doc# con: http://www.w3.org/2000/10/swap/pim/contact# dct: http://purl.org/dc/terms/
    1. Components.js is a dependency injection framework for JavaScript applications. Instead of hard-wiring software components together, Components.js allows these components to be instantiated and wired together declaratively using semantic configuration files. The advantage of these semantic configuration files is that software components can be uniquely and globally identified using URIs. Configurations can be written in any RDF serialization, such as JSON-LD. This software is aimed for developers who want to build modular and easily configurable and rewireable JavaScript applications.
    1. The "Standard" element is used to list all the relevant standards implemented by the project. These standards include W3C or ISO standards, RFCs, various technical specifications etc.
    1. Welcome to the DOAP wiki. DOAP is a project to create an XML/RDF vocabulary to describe software projects, and in particular open source projects.
    1. If you want to make the Semantic Web a reality, stop making the case for it and spend your time doing something more useful, like actually making machines smarter or helping people publish data in a way that’s useful to them.

      Soooo true !

    1. This document defines two new HTTP headers that enable User Agents and hosts to indicate and negotiate the profile used to represent a specific resource. In this context, a profile is a document describing the structural and/or semantic constraints of a group of documents in addition to the syntactical interpretation provided by a MIME type. Examples of profiles include Dublin Core Application Profiles, XML Schemata and RDF Shape Expressions. Further, it defines and registers the profile parameter for the HTTP Link header and suggests a best practice for the use of the new headers together with the Link header to perform content negotiation and point clients to alternate representations.
    1. The Hyper Text Coffee Pot Control Protocol (HTCPCP) is a protocol for controlling, monitoring and diagnosing coffee pots over a network. The Resource Description Framework (RDF) is a general-purpose language for representing information in the Web. This document defines HTCPCP Vocabulary in RDF in order to allow HTCPCP headers that have been exchanged between a client (in other words, a coffee addict) and a server (a networked device that can brew, store and deliver heated coffee beverages) to be recorded in RDF format. The objective of this vocabulary is to support quality assurance testing, and to serve as a machine-readable component in conformance claims and in reporting languages such as the Evaluation and Report Language (EARL) [EARL Schema].
    1. The Linked General Transit Feed Specification (Linked GTFS) is a mapping of the GTFS in CSV reference towards RDF.

    1. RDF Translator is a multi-format conversion tool for structured markup. It provides translations between data formats ranging from RDF/XML to RDFa or Microdata. The service allows for conversions triggered either by URI or by direct text input. Furthermore it comes with a straightforward REST API for developers.

    1. Outside the triple, information is lost and a literal is just data without any meaning.

      That does seem to be a problem.

    2. hey can not be subjects in RDF triples – they are always the objects used to describe a resource.
    3. Literals are nodes in an RDF graph, used to identify values such as numbers and dates by means of a lexical representation.

      Yeah! At last a definition I can understand!
