Hi Rob,

In my project I am using the following approach - URI are forever - the skos:Concept may be constraind in time using an applicability period - the skos Concept has a creation date. modification date and version(=introduction version) property - semantic relations are not versioned (skos would be more difficult to accommodate that) - Next to semantic relations, change-notes are used on versioned concepts. These change notes contain references to earlier/newr versions of a concept

This is sufficient for my curent projects

best.

Dear list members

The background to my questions is that we are currently considering developing a 'SKOS resolver' (for want of a better description) for our terminology management solution to sit alongside the other formats we currently implement.

This has however thrown up some questions.

As part of this requirement we (ideally)need to: 1 Expose versioning information 2 Allow identification of terminology changes between versions

As these are parts of our existing solution which are already exposed using other formats.

So...

1. How should we expose versioning information given that uri's for concepts are fixed (please don't say timestamps on uri's :))

2. How should we identify and manage change between revisions of concept schemes as this 'seems' to result in imprecision. e.g. a concept 'a' is currently in thes 'A' and only has a preferred label. A new revision of thes 'A' is published and what was concept 'a' is now a non preferred concept and thus becomes simply a non preferred label for a new concept 'b'.

It seems to me that this operation loses some of the semantic meaning of the change as all references to the concept id of 'concept a' would be lost as it now is only a non preferred

label of a different concept with a different id (concept 'b').

Any comments would be much appreciated.

Best Regards

Rob
