Semantic Web Best Practices and Deployment (SWBPD) Working Group Charter

Status of this Document

Per section 6 Working Groups, Interest Groups, and Coordination Groups of the W3C Process, this charter, and any changes to it, take effect by way of an announcement to the W3C Membership via w3c-ac-members.

This charter was approved by the W3C Director in an announcement to the W3C Membership on 25 February, 2004. The change log summarizes changes from the proposed charter.


The Semantic Web Best Practices and Deployment (SWBPD) Working Group is focused on providing consensus-based guidance - including practical deployment recommendations, engineering guidelines, ontology / vocabulary development practices, educational material and effective demonstrations, designed to facilitate Semantic Web deployment.


1. Scope

1.1 General aim

The aim of this Semantic Web Best Practices and Deployment (SWBPD) Working Group is to provide hands-on support for developers of Semantic Web applications. With the publication of the revised RDF and the new OWL specification we expect a large number of new application developers. Some evidence of this could be seen at the last International Semantic Web Conference in Florida, which featured a wide range of applications, including 10 submissions to the Semantic Web Challenge (see http://challenge.semanticweb.org/).This working group will help application developers by providing them with "best practices" in various forms, ranging from engineering guidelines, ontology / vocabulary repositories to educational material and demo applications.

This Working Group is intended to capitalize on work already been done. This work is typically spread over a range of disciplines and communities, combining experience from industry and computer science with research insights from fields as diverse as philosophy, linguistics, library science, psychology, conceptual modeling, and domain modeling, amongst others. This work is typically spread over a range of disciplines: philosophy, linguistics, library science, psychology, conceptual modeling, domain modeling, etc.

The working group will focus on four areas for providing support.

1.2 Focus areas

1.2.1 Focus: Supporting initiatives for publishing ontologies / vocabularies

In various domains large ontologies, including vocabularies and thesauri, have been constructed. Typically, these corpora are the result of many years of collaborative effort in a community. Such corpora form indispensable resources for Semantic Web applications. One prime objective of the SWBPD Working Group is to help make these resources publicly available for application developers.

To this end the working group will undertake the following activities:

The result should be a set of publicly available high-profile ontologies. The following is an indicative (nonlimitative) list of existing ontologies at which this focus area is targeted:

Criteria for an ontology to be within the scope of this Working Group are:

Related works to be considered include SWAD Europe work on thesauri, SchemaWeb as well as similar initiatives.

1.2.2 Focus: FAQs and how-to-do-it guidelines

The goal of this focus area is to provide support for practical issues related to ontology / vocabulary engineering and use for the Semantic Web.

The Working Group will be the sponsoring group for the RDF in XHTML Task Force [charter, work plan], currently chartered under the Semantic Web Coordination Group. The Working Group will, in conjunction with the HTML Working Group, provide a solution for representing RDF metadata within an XHMTL document.

Additional task forces may be created to investigate specific deployment issues, especially those which have a connection to other W3C work. The development of an RDF Schema or OWL Ontology for the XML Schema datatypes is an example of such a task force.

Other Working Group Notes may be developed from topics brought by Working Group participants. Research topics are out of scope. Examples of possible guideline development include:

to the extent that these topics (above) consider practical deployment questions and avoid areas of research. The WG should give priority to topics concerning interoperability as well as to topics that relate to other W3C work.

The Working Group may choose to create or contribute to an index of:

Working Group Notes that could be produced:

1.2.3 Focus: Repository of tools and demo applications

The Working Group will cooperate with and contribute to efforts to maintain a Tool and application index. This index should provide data in RDF and OWL format in addition to a human-friendly presentation format. The index should provide only references to materials when they have a home elsewhere in the Web but may host materials developed by or contributed to the Working Group. The Working Group may choose to offer some 'value add' by highlighting materials that in its view support the Working Group's other Focus Areas in some noteworthy manner.

Preference is given to open-source software.

NOTE: This focus area is likely to be carried out in coordination with activities in the DAML program, e.g. on open-source tools for OWL.

1.2.4 Focus: Links to related techniques

The Working Group will consider publishing Working Group Notes on links to related (standardization) efforts. The goal of such notes will be to provide guidelines for users who want to combine usage of the two fields. Typical topics for such notes would be:

This should typically be done in cooperation with the other organizations involved (MPEG, OASIS, OMG)

1.3 Out of scope

2. Deliverables and Schedule

This Working Group is chartered for a duration of 23 months, through 1 May 2006. The kick-off meeting is planned to be held on March 4-5 2004 at the W3C Tech Plenary in Cannes.

The Working Group will initiate task forces for producing Working Group notes. These task forces will typically operate in the following way:

The Working Group may consider using Wiki techniques to facilitate its work, particularly for data collection or FAQs, however formally edited and published Working Group Notes are to be preferred over Wikis for dissemination of guidelines. When the material is appropriate, the Working Group will use the W3C Recommendation Track Process to propose the advancement of technical reports to Recommendation.

The Working Group will consider producing a short note about how the Working Group determines what is a best practice, e.g. that it should be based on real implementations. The best-practices process of the OASIS UDDI Spec TC could serve as useful input.

3. Relationship with Other Activities

3.1 W3C-related activities

3.2 External groups

4. Membership, Meetings, and Logistics

To become a participant of the Working Group, a representative of a W3C Member organization must be nominated by their Advisory Committee Representative (details on how to join are on the group home page). The nomination must include explicit agreement to this charter, including its goals, the level of effort required and an IPR disclosure.

Experts from appropriate communities may also be invited to join the working group, following the normal process.

Each Working Group participant is expected to contribute 20%, or at least a day per week to this group.

All proceedings of the Working Group (mail archives, telecon minutes, ftf minutes) will be available to the public.

Working Group participants are not obligated to participate in every task force, however the Working Group as a whole is responsible for reviewing and accepting the output of each task force. Task force participants are expected to participate in WG face-to-face meetings and telecons where the work of the task force is on the agenda.

4.1 Email communication

The mailing list for group communication is public-swbp-wg@w3.org with a publicly readable archive.

4.2 Group home page

The Working Group will have a home page that records the history of the group, provides access to the archives, meeting minutes, updated schedule of deliverables, membership list, and relevant documents and resources. The page will be available to the public and will be maintained by one of the co-chairs in collaboration with the W3C team contact.

4.3 Telephone meetings

The Working Group will hold teleconferences approximately every two weeks. Participation in phone conferences is limited to members of the working group. The Chair may, at his discretion, invite guest experts to attend particular phone conferences. An IRC channel may be used to supplement teleconferences.

Meeting records should be made available within two days of each telephone meeting.

4.4 Face-to-face meetings

Participation in face-to-face meetings is limited to working group members and observers invited by the Chair. Observers may take part in decision-making at the discretion of the Chair.

In addition to the required two annual face-to-face meetings, the Working Group may schedule other face-to-face meetings in a manner that maximizes co-location with events that Working Group members might be attending anyway.

The Chair makes Working Group meeting dates and locations available to the group at least eight weeks before the meeting, per W3C Process.

5. Resources

5.1 Working Group participation

To be successful, we expect to have between 10 and 20 active participants for the duration of this Working Group. We also expect a large public review group that will participate in the mailing list discussions.

5.2 W3C team involvement

The W3C Team expects to allocate the equivalent of 40% of a full-time person to this work for the duration of this working group; through 1 May 2006. This time includes the Team Contact effort as well as additional participation.

6. Intellectual Property Rights

This Working Group operates under the W3C Patent Policy (5 Feb 2004 Version). To promote the widest adoption of Web standards, W3C seeks to issue Recommendations that can be implemented, according to this policy, on a Royalty-Free basis.
