Re: Alignment between SKOS and new ISO 25964 thesaurus standard

Hi all,

Our research group is finalizing an ontology based on ISO. The design is
based on a careful analysis of the new standard. Following the same we
conclude that ISO 25964-1/2 is practically impossible to map correctly with
SKOS in the most important aspects.

The goal of the ontology we are designing is to make a bridge between the
ISO and SKOS model. In fact the model proposed by ISO lacks adequate
semantics for drawing inferences.

In my opinion we should consider several points:

* First, SKOS is being so used because of its simplicity. SKOS provides all
the basic principles of knowledge organization systems. ISO includes all
cases of use in the design of a thesaurus starting from the most complex
case. The current "core" of SKOS need not be modified.

* Second, the data model of ISO 25964-1/2 is very focused on storage of
thesaurus data in a relational database.

* Third, instead of changing SKOS, an extension could be designed similar
to SKOS-XL (SKOS-ISOTHES?). This extension should include (mainly) the
compound equivalence of concepts, labeled semantic relationships and
mappings relationships described in 25964-1/2.

It would not be necessary to include a errata, as the basis of SKOS still
based on ISO 2788/5964. Maybe, designing an SKOS extension based on ISO
25964-1/2 could be a solution that maintains interoperability of SKOS
applications that have been made so far.

Juan
