Dear all,
This version cuts the TF description per se down to one page
-- much shorter than the previous draft [1]. I have also cut
the "Dependencies" section down to a list of W3C documents
of relevance to the chosen scope. I would appreciate some
guidance and feedback from W3C process veterans, as well as
from working group members, on whether this document can be
considered "done" as a TG description.
My vacation starts soon, and August is a bad month to try to
work as a group, so I propose we plan to start moving again
late in August. I will take the older draft as a starting
point and integrate any comments or references such as Jeremy's
or any others that may come in over the next few weeks.
For those listed as "members" who have not yet confirmed,
please let me know at your convenience.
Tom

SWBPD "Vocabulary Management" Task Force Description
Draft, 2004-06-25
NAME
Vocabulary Management
STATUS
Considered

MEMBERS
Libby Miller (University of Bristol)
Natasha Noy (Stanford University)

OBJECTIVES
1. To establish the terminology for our discussion of the
declaration, identification, use, and management of
vocabulary terms in a Semantic Web environment -- i.e.,
to list and define terms such as Term, Vocabulary,
and Namespace.
2. To articulate assumptions regarding the use of terms in
a Semantic Web environment.
This section can be short, but our guidelines may not make
sense to readers if we do not say something about our
assumptions. These assumptions could include: an open,
loosely-coupled, mixed-language environment ("the Web");
distributed and bottom-up processes for defining and
publishing vocabularies; the need to support the evolution
of languages; well-known Web principles such as the "Must
Ignore Principle" and "The Principle of Free Extension";
the need to support processes for repurposing and merging
data from many sources; and visions of future Semantic
Web infrastructures (e.g., "registries").
3. To articulate guidelines of good practice for Namespace
Owners to identify and declare Terms and Term Sets
(Vocabularies) for use in a Semantic Web environment.
Starting with fundamental guidelines such as "Identify Terms
using URIs", this section should formulate good-practice
advice in areas where a workable consensus has developed on
topics such as the backwards and forwards compatibility
of URI-identified terms; the documentation of terms;
"namespace" policies; "ownership" of namespaces; and
approaches to versioning terms and identifying term
versions.
4. To point to and briefly summarize ongoing the evolving
diversity of practices and approaches to declaring and
managing vocabularies.
Any issues on which a workable consensus has not yet been
reached on good practice in the wider Web community should
be discussed in such a way as to clarify the range of
different approaches. Examples are the question of what
sort of human-readable or machine-processable documents, if
any, Term URIs should "resolve to"; how an organization or
even an individual can go about declaring and publishing a
term or a vocabulary; and how "good" URIs should be formed.
APPROACH
The issues above have been discussed and documented in
various vocabulary maintenance communities. The Task
Force deliverable will provide an overview of the issues
and principles involved in declaring and maintaining
a vocabulary, pointing to available examples of good
practice. In order to do this, it must first define
a common terminology for describing the diversity of
practices in a comparable manner.
SCOPE
Guidelines and principles for the identification,
declaration, and management of Terms in Vocabularies
(Metadata Element Sets, Thesauri, Ontologies, Published
Subjects, and the like).
DELIVERABLE
A relatively concise (fifteen-page?) technical note
summarizing principles of good practice, with pointers to
examples, about the identification of terms and term sets
with URIs, related policies and etiquette, and expectations
regarding documentation.
TARGET AUDIENCE
-- Maintainers of terms and term sets (vocabularies)
for use in a Semantic Web environment.
-- Anyone else wishing to declare terms reusably.
