<h2><a name="sec1" id="sec1">1. Scope</a></h2>
|
|
|
|
<p>The objective of the Semantic Web Deployment Working Group (SWDWG) is to
|
|
develop "how to" guidelines that assist users of the Semantic Web in
|
|
publishing data and vocabularies that describe data in the Semantic Web. Some
|
|
of these guidelines will be published as Working Group Notes and others will
|
|
be Recommendation-track documents.</p>
|
|
|
|
<p>This Working Group is intended to capitalize on work already done both
|
|
within W3C and outside W3C. In particular, SWDWG takes as it starting point
|
|
work started in the <a
|
|
href="http://www.w3.org/2001/sw/BestPractices/OEP/">OEP</a>, <a
|
|
href="http://www.w3.org/2004/03/thes-tf/mission">PORT</a>, <a
|
|
href="http://www.w3.org/2001/sw/BestPractices/VM/">VM</a>, and <a
|
|
href="http://www.w3.org/2001/sw/BestPractices/HTML/">HTML</a> Task Forces of
|
|
the <a href="http://www.w3.org/2001/sw/BestPractices/">Semantic Web Best
|
|
Practices and Deployment Working Group</a> (SWBPD).</p>
|
|
|
|
<p>Domain experts produce ontologies, thesauri, and vocabularies for
|
|
incorporation into the Semantic Web. Though these works are domain-specific,
|
|
questions arise that are common to each of these efforts on how to take best
|
|
advantage of the Semantic Web technologies to deploy these works. There are
|
|
interactions with principles of Web architecture that have evolved since the
|
|
initial deployment of the Semantic Web and were sometimes overlooked by the
|
|
early adopters. The established pattern of emulating existing RDF schemas or
|
|
OWL ontologies can therefore lead to propagating unfavorable practices. There
|
|
are deployment questions in practical use of OWL that arise repeatedly as new
|
|
communities investigate how to employ Semantic Web tools. Questions such as
|
|
how in practice to use OWL to achieve semantic integration across different
|
|
agents, services, and applications; how to identify multiple versions of a
|
|
vocabulary; how to manage the contents of the namespace document(s), and
|
|
more.</p>
|
|
|
|
<p>The Simple Knowledge Organisation System (<a
|
|
href="http://www.w3.org/TR/swbp-skos-core-spec">SKOS</a>) was developed as
|
|
part of the <a
|
|
href="http://www.w3.org/2001/sw/Europe/reports/thes/">SWAD-Europe Thesaurus
|
|
Activity</a> and subsequently taken up by SWBPD to provide guidelines on
|
|
porting thesauri to the Semantic Web. SKOS has proven useful in describing
|
|
the basic structure and content of concept schemes such as thesauri,
|
|
classification schemes, subject heading lists, taxonomies, 'folksonomies',
|
|
and other types of controlled vocabularies. SKOS has come to have a
|
|
sufficiently important role to the community that it merits the rigorous
|
|
review of the W3C Recommendation Track process. Some SKOS concepts interact
|
|
with similar features of OWL and those interactions need to be explained in
|
|
the context of practical deployment considerations.</p>
|
|
|
|
<p>The SWDWG will continue the work of the previous SWBPD Working Group to
|
|
produce guidelines and an RDF vocabulary (SKOS) for transforming an existing
|
|
vocabulary representation into an RDF/OWL representation. The Working Group
|
|
will also produce guidelines for the most appropriate use of Web protocols to
|
|
make these representations available in a manner consistent with the work of
|
|
the W3C Technical Architecture Group. A starting point for this work is the
|
|
"<a href="http://www.w3.org/TR/swbp-vocab-pub/">Best Practice Recipes for
|
|
Publishing RDF Vocabularies</a>" Working Draft produced by SWBPD.</p>
|
|
|
|
<p>The SWDWG is chartered to produce additional Working Group Notes on
|
|
ontology engineering practices appropriate to the deployment of RDF Schema
|
|
and OWL. These may include, at the discretion of the Working Group
|
|
participants, further work on <a
|
|
href="http://www.isi.edu/~pan/SWBP/time-ontology-note/time-ontology-note.html">time</a>,
|
|
<a
|
|
href="http://www.isi.edu/~pan/SWBP/time-zone-note/time-zone-note.html">timezone</a>,
|
|
and units of measure ontologies in OWL that were started in the <a
|
|
href="http://www.w3.org/2001/sw/BestPractices/OEP/">OEP task force</a> of the
|
|
SWBPD Working Group. Specific 'horizontal' vocabularies other than those
|
|
listed above are outside the scope of this charter.</p>
|
|
|
|
<p>Finally, the SWDWG is chartered to complete the collaboration with the W3C
|
|
HTML Activity to specify a W3C Recommendation on incorporating RDF semantics
|
|
directly into HTML documents. While the expected W3C Recommendation may
|
|
involve changes to the specification of HTML and is therefore the
|
|
responsibility of the HTML Activity, practical deployment guidelines within
|
|
the Semantic Web are the responsibility of SWDWG. The Working Group is tasked
|
|
to consider two options to meeting requirements it will write in the first 6
|
|
weeks of work. The first option is to use <a
|
|
href="http://www.w3.org/TR/xhtml-modularization/">XHTML Modularization
|
|
1.1</a> to specify an RDF Semantics module that can be combined with existing
|
|
W3C XHTML 1.1 modules. The second option is to identify, in close cooperation
|
|
with the HTML Working Group, changes to XHTML Modularization 1.1 or to other
|
|
HTML specifications that would lead to an improved technical solution
|
|
(hereafter called "RDFa") over option 1 and provide requirements to the HTML
|
|
Working Group against which it can evaluate those suggested changes. The
|
|
Requirements and Use Cases on Incorporating RDF Semantics Into XHTML Working
|
|
Draft [to be written in the first 6 weeks] will guide the selection of option
|
|
1, option 2, or some combination thereof. The Requirements and Use Cases will
|
|
include an explanation of how these technologies compare to related efforts
|
|
such as microformats.</p>

|
|
Working Group and Interest Group Participation Requirements</a> of the W3C
|

Process and is not further constrained.</p>
|
|
|
|
<p>Participation is expected to consume approximately one half day per week
|
|
of each Working Group participant's time, including weekly remote
|
|
meetings.</p>
|
|
|
|
<p>All proceedings of the Working Group (mail archives, telecon minutes,
|
|
face-to-face minutes) are available to the public using a mailing list,

public-swd-wg@w3.org, and its associated Web archive. The Working Group
|
|
telecons and face-to-face meetings are not themselves public meetings.</p>
|
|
|
|
<p>If the Working Group chooses to establish task forces to work in parallel,
|
|
Working Group participants are not obligated to participate in every task
|
|
force, however the Working Group as a whole is responsible for the output of
|
|
each task force. Task force participants are expected to participate in all
|
|
Working Group face-to-face meetings and telecons.</p>

|
|
<p>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
|

<p>The Working Group will hold teleconferences on a regular schedule as
|
|
agreed by the Working Group participants but at least every two weeks.
|
|
Participation in teleconferences is limited to Working Group working group
|
|
members. The Chair may, at his/her discretion, invite guest experts to attend
|
|
particular phone conferences. An IRC channel will be used to supplement
|
|
teleconferences.</p>
|
|
|
|
<p>Meeting records should be made available within two days of each telephone
|
|
meeting.</p>

|
|
|
<p>To be successful, we expect to have between 8 and 20 active participants

|
|
<p>The W3C Team expects to allocate the equivalent of 20% of a full-time

person to this work for the duration of this working group. This time
