Re: SKOS Implementation: Vocabulary and alignment repository

Hello,

Here is the description, according to the implementation format, of the service announced in [1] (below):

CATCH Vocabulary and Alignment service

Lourens van der Meij, Antoine Isaac, Vrije Universiteit Amsterdam

Yes

Yes

No

See the anouncement mail [1].
The program supports almost the SKOS constructs that are *not* Collection-related constructs and SKOS-XL extension constructs.
