Hi Pepijn

Some thoughts to discuss about sesame.

Creating/modifying
- -----------------------
- - When getting the keywords from sesame do we still need the search 
for keywords or is it possible to get only related keywords and show 
them all? I hope it's possible to generate a specific enough query that 
a search becomes obsolete.
- - How do we store the chosen keywords in a workunit/subproject/... We 
don't have a unique key (at least I haven't found one). Does this mean 
that we need to store the rdf tuple we have selected?

Indexing
- ----------
- - We probably will need to index the whole tuple (e.g. keyword) to 
make able in the search if its narrower or brother.

Search
- ---------
- - Give the user the possibility to select specific tuples, indicate if 
explicit/broader/narrower search shall be done and then execute the 
search on our lucene index with the given arguments.

I suggest to start with the creating/modifying task. This will have the 
benefit that the stored keywords are consistent with a given ontology 
and can be searched via legacy search if the 'ontology-based' search is 
not (fully) implemented.


WDOT?
