Hi Sarah,
Yep, there's a certain amount of arbitrary duplication between 1.5
keyword, 9.4 keyword and 9.2 taxonPath. TaxonPath is the only one that
allows you to give a "source". So if you want to tell people which
controlled vocabulary you are using then either you use 9.2 taxonPath or
you have to rely on people knowing your application profile (and the
latter only works if you're only using one source for all records--and I
know scenarios where a single record ends up with keywords from
different sources).
The RDN LTSN LOM Application profile uses 1.5 for (uncontrolled)
keywords and 9.2 for taxonomies used for browsing, some of which are
based on controlled vocabularies / thesaurii. (Uncontrolled is in
brackets because I don't whether individual centres/hubs are using
controlled keywords in 1.5, the point is that there is no control across
the project as a whole.) It is also suggested that the terms used in the
taxon path might be reproduced in 1.5 so that they are searched by those
systems that don't automatically search the taxonPath when a user does a
free text search.
I'll let CanCore know about the inconsistency in their Guidelines.
All the best, Phil.
