RDF Interest Group

This is the home page for the RDF Interest Group, established in August 1999 as an open forum for W3C Members and non-Members to discuss issues relating to W3C's Resource Description Framework.

Issues and Scope

The RDF Interest Group provides a forum for discussion of a wide range of RDF-related activities and issues. From the charter:

...the Interest Group will explore the application of W3C metadata technology in the context of the social, legal, and technological issues surrounding Internet content selection, filtering, labelling, signing, quality assurance etc. Other topics in scope for the Interest Group include RDF query in the context of the Semantic Web roadmap, intellectual property rights, P3P, and electronic commerce.

Meetings

The RDF Interest Group will be meeting for two days as part of the W3C Technical Plentary and WG Meeting Event (Royal Sonesta Hotel, Cambridge, Massachusetts USA). ( announcement)

The agenda is still being finalised, but will address topics such as...

• The new Semantic Web Activity and RDF Core Working Group - what does this mean for RDF and the RDF Interest Group?
• Show and tell: developer experiences of working with RDF
• RDF and XML: relationship to other XML-based specs (XLink, XSLT, XML datatypes...)
• RDF Issue Tracking document: current state and future maintainance
• RDF Bugathon and Parser Test Suite: implementation testing the RDF Core
• ...

Documents

The RDF home page tracks most RDF developments. Here we list a few documents and proposals circulated in particular to the RDF IG community.

While the RDF Interest Group is free to explore any topics and concerns, the conclusions of the Cambridge Communiqué may help guide discussion:

• 8. A new simplified XML transfer syntax for RDF and an API for accessing RDF data models should be produced. The RDF 1.0 transfer syntax remains a W3C Recommendation and applications are free to continue to use it.

Spec-related

• RDF Interest Group - Issue Tracking (announcement)
• discussion strawman: RDF Data Model Summary (excerpted from M+S REC, see announcment).

  • see also XLink Markup Name Control, W3C Note 24 October 2000, which describes the use of XML Schema for representing linking constructs in XML markup

RDF APIs

• RADIX RDF API revisited (Nov 1999 overview)
• An RDF API Draft from Sergey Melnik, Stanford databases group, submitted for discussion and collective development to www-rdf-interest

• Contexts for RDF Information Modeling, Graham Klyne. posted Tue, Sep 05 2000.
• see also: Design Issues and the various issue summaries linked from the RDF Issue Tracking page

RDF Syntax

Services and Query languages

QL'98 position papers on RDF query:

• Enabling Inferencing, R.V. Guha (Netscape), Ora Lassila (Nokia), Eric Miller (OCLC), Dan Brickley (Bristol).
• Query + Metadata + Logic = Metalog, Massimo Marchiori, Janne Saarela (W3C). See also metalog implementation

• RDF Description Services (23rd Nov 1999)

RDF IG mailing list(s)

The RDF community is encouraged to adopt the interest group's mailing list, www-rdf-interest@w3.org as the primary mailing list for discussion of RDF-related matters. See the Interest Group charter for more details of the role and scope of the interest group. Public archives of the www-rdf-interest list are available.

To subscribe to the mailing list, send a message:

 To: www-rdf-interest-request@w3.org
    Subject: subscribe

To send to the list, use the address www-rdf-interest@w3.org.

The more specialised RDF-Logic list can be accessed in the same fashion (announcement).

The archives of the RDF IG can be searched using this Web form...

Internet Relay Chat (IRC)

Member of the RDF developer community can also augment mailing-list discussions with real time chat tools. IRC is one such tool. There are a number of public IRC servers in existence: while W3C does not run such a server for general developer discussions, members of the Interest Group can sometimes be be found on the Open Projects IRC Network (channel #rdf)

Other lists

There are a lot of mailing lists hosted by W3C. Further information is available on these.

The (defunct) RDF-DEV list has its own home page and resources guide. Since 1999-10-22, new members of RDF-DEV are being redirected to the RDF Interest Group mailing list by the listowner, to encourage convegence between the RDF-DEV and RDF IG communities.

There has been a fair amount of discussion on the www-rdf-comments list, whose main purpose is feedback and comments on the RDF Specifications. The Mozilla RDF forum has also been the focus of some general RDF-related discussions.
