Re: [SKOS] application in indexing and search

Hi Johan!

We are developing in this direction for practical projects in Brussels 
and in Alsace. Publicly accessible results should be visible by the end 
of the winter: http://www.windmusic.org

DSpace is the first target application but we target any Java 
application (JSPWiki is the next we will tackle)
1) Authority lists / thesaurus are loaded statically or dynamically in 
memory from different sources (SQL, XML, CSV files; RDF should be 
supported when useful using RIO).
2) Memory model and API is aligned on SKOS concepts and terminology
3) Services include:
   a) indexation expansion (synonyms, translations, broaders) for word 
searches
   b) Autocomplete to help cataloguers but also searchers
   c) Search using "concepts" rather than words
   d) Display using proper terms for user language (and not the code or 
other terms)
   e) Hierarchical browsing in thesauri trees
   f) Display of usage count of concepts in different applications and 
applications indexes
  g) Export "in context" (data reduced to what is pertinent for a given 
user) in XML piped in XSLT transformation.

The module is buffering data so cataloguing / search / display speed is 
optimal.

The global aim of the project is presented at http://www.askosi.org
The motivation for one of the current projects is explained in 
http://eprints.cilea.it/conf/viewpaper.php?id=197&print=1&cf=11

Our goal is to participate in projects which aim at maximizing the user 
value of information databases (ergonomics, functionalities, content 
management, efficiency). We would be very happy to participate to SKOS 
Application Services (this is more than data modeling) standardization 
efforts.

Wishing you a very nice day (in Belgium, you may have to stay inside!)
