Hello,

Concerning pattern A, as I said today almost all deployed 
thesaurus-based information management system (e.g. in library) should 
provide an example for pattern A. I can provide with a quick example at
http://www.kb.nl/kb/manuscripts/browser/index.html
Manuscripts illuminations have been described (indexed) using the 
Iconclass concept scheme, and you find it based on your selecting a 
concept in the browser and the existing indices for the collection 
records (illuminations)

For pattern B, the situation is different since it is newer. In my 
project we have built a small demo trying to access to 2 collections 
indexed with different vocabularies using one or the other. The browser 
(from http://stitch.cs.vu.nl/demo.html) uses a semantic-web enabled 
representation of the vocabularies, and links between the different 
concepts of these two vocabularies. Of course the setting is not really 
professional, but at least it can give you an idea of what this pattern 
is about.

Interesting is that people from the library/museum world are getting 
more and more interested in these interoperability matters. And we might 
have soon some more realistic use cases as input, mixing the ideas 
behind such demo and real portals accessing several collections, like 
www.theeuropeanlibrary.org, or some more internal situations (e.g. an 
institute willing to merge two vocabularies it has been using for years, 
but wanting to keep its old data available).

Well, everything is quite centered around my own interest, but hopefully 
it can give some ideas on the issues Alistair discussed. Notice that 
(still in my neighbourhood) the Multimedian eCulture 
http://e-culture.multimedian.nl/ project has a very nice demo for 
browsing collections with several vocabularies. Technically I think it 
is an instance of pattern A (Guus, correct me if I'm wrong, and some 
mapping was done!), even if a lot vocabularies are used at the same 
time, which makes it a very semantic web-intensive case!

Best,

Antoine
