Associating Resources with Namespaces

  • This Finding addresses the question of how ancillary information (schemas,
    stylesheets, documentation, etc.) can be associated with a namespace.

Uniform Access to Metadata

  • This document surveys the problem of specifying a uniform method
    for obtaining information pertaining to a resource without
    necessarily having to parse a representation of the resource. It is an
    attempt to rationalise several discussions that have taken place in a
    variety of e-mail fora. More background and links to e-mail threads
    area available on the wiki

The Self-Describing Web

  • The Web is designed to support flexible exploration of information by human users and by automated agents.
    For such exploration to be productive,
    information published by many different sources and for a variety of
    purposes must be comprehensible to a wide range of Web client software.
    HTTP and other Web technologies can be used to deploy resources that are
    self-describing, in the sense that only widely available information is necessary for understanding them.
    Starting with a URI, there is a standard algorithm that a user agent
    can apply to retrieve and interpret a representation of such resources.
    Furthermore, when such self-describing resources are linked together, the Web as a whole can support reliable,
    ad hoc discovery of information.
    This finding describes how document formats, markup conventions, attribute values, and other data formats can be designed to facilitate the deployment of self-describing Web content.
  • The Web is designed to support flexible exploration of information, by human users and by automated agents.
    For such exploration to be productive,
    information published by many different sources and for a wide variety of
    purposes must be comprehensible to a wide variety of Web client software.
    This finding suggests that there are three strategies that, used in combination, can ensure
    such flexible interoperability: 1) where practical, resource representations should be encoded using widely deployed standards; 2) where such widely deployed standards are not sufficient, the encodings used should themselves be described in machine readable form on the Web, using RDF, RDDL, or other standard description systems; and 3) in all cases, each representation should carry information such as media-types, character encoding labels, RDFa, links to specifications, etc. sufficient to support automatic determination of the standards and other specifications necessary for correct interpretation.
    To the extent that these guidelines are observed, individual documents become self-describing, in the sense that only widely available information is necessary for understanding them.
    Furthermore, when such documents are linked together, the Web as a whole can support reliable,
    ad hoc discovery of information.
    This finding discusses in more detail the techniques needed to create such a self-describing Web.

CustomRdfDialects - ESW Wiki

  • An RDFa document can use GRDDL with something like RDFa profile by Fabien Gandon.

    Other custom dialects include:

XHTML metainformation profile

  • This document, http://purl.org/net/ns/metaprof, is a metadata profile for XHTML, as well as an RDDL namespace document for GRDDL transformation. (Note: please use this profile for Well-formed XHTML (not HTML4 etc.) because GRDDL agent will want to try XSLT transformation.)

A meaningful Web for humans and machines, Part 1: How humans can share the wealth of the Web

  • In this series of articles we'll examine the existing and emerging technologies that enable machines and humans to easily access the wealth of Web-published data. We'll discuss the need for techniques that derive the human and machine-friendly data from a single Web page. Using examples, we will explore the relationships between the different techniques and will evaluate the benefits and drawbacks of each approach. The series will examine, in detail: a parallel Web of data representations, algorithmic approaches to generating machine-readable data, microformats, GRDDL, embedded RDF, and RDFa.

Modernising Semantic Web Markup


  • The Resource Description Framework (RDF) web metadata format has an
    XML syntax RDF/XML which has been described as a ugly and flawed,
    mainly as a consequence of it being an early XML format, dating from
    1998. This presentation will describe the perceived and real
    problems and select appropriate modern XML and web best practices for
    improving RDF markup that can be better used with the latest XML
    technologies such as XSLT 2 and XQuery.



    The presentation will distinguish a semantic web markup format rather
    than a format intended solely for software as one intended to be
    easier for end users to author and more clearly be appropriate for
    typical application areas of lightweight web metadata and authored
    web ontologies.



    XML best practice in any area is a tricky subject to discuss and get
    agreement on but the XML technologies considered include XML
    Namespaces, XML QNames in content, omitting some darker corners of
    the XML specification along with use of clear user-friendly
    technologies such as the RELAXNG grammar-based XML schema language,
    part of the ISO DSDL work. The presentation will also discuss
    approaches starting from XHTML to generate semantic web data.

Raw » Microformats on the GRDDL
