Guide to Term Summary Tables

Each term (i.e. class or property) of the SKOS Extensions vocabulary is summarised in this document as a table. Each table may have the following rows:

SKOS RDF Vocabulary Evolution and Management

SKOS Extensions is a living vocabulary, which means it may continue to evolve indefinitely.

Each term in the vocabulary has a term status level assigned. The status of a term indicates its level of stability, i.e. how much it may be expected to change in the future. The following status values are allowed:

unstable

The term is unstable, and feedback is welcomed on it's current form and utility (analagous to 'alpha' release in software development). It may currently be poorly defined. It's meaning and/or form may be expected to change at any time. Do not implement mission critical systems that depend on this term persisting in its current form.

testing

The term has gone beyond the raw proposal stage, and is undergoing testing (analagous to 'beta' release in software development). This term may still change in response to feedback from testing, although it may be expected not to undergo any radical change. The cost to early implementors of changing the term will be considered, however the goal of achieving wider interoperability and long-term stability may override those considerations.

stable

No substantial (meaning changing) alterations will take place. Implementors can expect the term to persist in its current form indefinitely.

A term may also be marked as deprecated, in which case instructions will be given on what to use in its place.

Taking Part in SKOS Development

SKOS Extensions are maintained by an open community of developers, users, and domain experts. All development work is discussed via the public-esw-thes@w3.org mailling list. This mailing list is public, and anyone is free to subscribe and/or post mails. A public archive of the mailing list is also available online [PUBLIC-ESW-THES ARCHIVE].

Proposals for additions or modifications to SKOS Extensions may be made via the public-esw-thes@w3.org mailing list. These are reviewed by the members of the mailing list, and if a reasonable consensus is reached, an action is taken.

See the reference [SKOS DEVEL] for more information.
