[Dspace-general] Controlled Vocabulary

[Stuart Macdonald]

We're in the process of setting up a pilot digital repository of 
cross-disciplinary research datasets produced at the University of 
Edinburgh (see URL: http://datashare.edina.ac.uk/dspace/) - one of the 
issues we're grappling with at the moment is the idea of a controlled 
vocabulary. There appears to be 2 'default' controlled vocabulary 
schemes in xml supported by DSpace (namely the Norwegian Science Index 
and the Swedish Research Subject Categories) which can be utilised by 
the keyword entry box.
Does anyone have any advice or information regarding the implementation 
of other schemes such as UDC, DDC, LCC? For example , are we correct in 
thinking that we'd have to 'purchase' the classification scheme (in the 
case of UDC it's about £2000 p.a.) or are there DSpace instances that 
are freely available?

Any clarity and/or assistance in this matter would be appreciated.

Stuart Macdonald
