This page summarizes the relationships among specifications, whether they are finished standards or drafts. Below, each title
links to the most recent version of a document.

Completed Work
W3C Recommendations have
been reviewed by W3C Members, by software developers, and by other
W3C groups and interested parties, and are endorsed by the
Director as Web Standards. Learn more about the W3C Recommendation
Track.
Group Notes are not standards and do not
have the same level of W3C endorsement.

GRDDL is a mechanism for Gleaning Resource
Descriptions from Dialects of Languages. This
GRDDL specification introduces markup based on existing standards for
declaring that an XML document includes data compatible with the
Resource Description Framework (RDF) and for linking to algorithms
(typically represented in XSLT), for extracting this data from the
document.
The markup includes a namespace-qualified attribute for use
in general-purpose XML documents and a profile-qualified
link relationship for use in valid XHTML documents. The GRDDL
mechanism also allows an XML namespace document
(or XHTML profile document) to declare that every document associated
with that namespace (or profile) includes gleanable data and for
linking to an algorithm for gleaning the data.

This document reports on implementations of the Direct Mapping
specification, and R2RML specification. The main purpose of this
document is to show that each feature of the Direct Mapping and R2RML has been
implemented by demonstrating interoperable implementations of each feature. To
evaluate the coverage of an implementation's features, the RDB2RDF Test Cases
are used as a point of reference.

The Resource Description Framework (RDF) is a model developed by the
W3C for representing information about resources in the World Wide Web.
Topic Maps is a standard for knowledge integration developed by the ISO.
This document contains a survey of existing proposals for integrating
RDF and Topic Maps data and is intended to be a starting point for
establishing standard guidelines for RDF/Topic Maps
interoperability.

Both XLink [XLink] and RDF [RDF] provide a way of asserting relations between
resources. RDF is primarily for describing resources and their
relations, while XLink is primarily for specifying and traversing
hyperlinks. However, the overlap between the two is sufficient that
a mapping from XLink links to statements in an RDF model can be
defined. Such a mapping allows XLink elements to be harvested as a
source of RDF statements. XLink links (hereafter, "links") thus
provide an alternate syntax for RDF information that may be useful
in some situations.
This Note specifies such a mapping, so that links can be
harvested and RDF statements generated. The purpose of this
harvesting is to create RDF models that, in some sense, represent
the intent of the XML document. The purpose is
not to represent the XLink structure in enough detail that
a set of links could be round-tripped through an RDF model.

This document is a report of the results of a meeting of a group
of W3C Members involved in XML
and RDF to advance the general
understanding of a unified approach to the expression of Web data
models. This document is one response to the Web data architecture
discussed in "Web
Architecture: Describing and Exchanging Data".

This document defines data categories and their implementation as a set of elements and attributes called the Internationalization Tag Set (ITS) 2.0. ITS 2.0 is the successor of ITS 1.0; it is designed to foster the creation of multilingual Web content, focusing on HTML5, XML based formats in general, and to leverage localization workflows based on the XML Localization Interchange File Format (XLIFF). In addition to HTML5 and XML, algorithms to convert ITS attributes to RDFa and NIF are provided.

This specification defines rules and guidelines for adapting the RDFa Core
1.1 and RDFa Lite 1.1 specifications for use in HTML5 and XHTML5. The rules
defined in this specification not only apply to HTML5 documents in non-XML and
XML mode, but also to HTML4 and XHTML documents interpreted through the HTML5
parsing rules.

An overview of usage scenarios and implementations demonstrating
applications of the Internationalization Tag Set (ITS) 2.0. The usage scenarios
are ranging from simple machine translation or human translation quality check
to training for machine translation systems or automatic text analyis.

These use-cases document the need to expose data from relational
databases (RDB) as RDF on the Web of data, and so deliver a set of
functional requirements for a standardized mapping language.
