Hi Sebastian!
Thank you for your quick answer.
Please find inline my additional comments and questions.

Oggetto: Re: Jeromedl customization: localization of taxonomies, wordnet =
vocabulary, and indexing properties

Giuseppe,

a quick answer to your questions (although might not be complete):

1) JeromeDL uses JOnto project [http://sf.net/projects/jonto] (yet =20
another from my Corrib cluster) to handle controlled vocabularies. =20
Hence to deliver new taxonomy you just need to have it in a properties =20
file or RDF file (e.g. SKOS compliant), and you simply need to =20
implement two interfaces in java and package it. The whole process =20
does not take much effort. @Mateusz - could you provide a step by step =20
description on a wiki?

Well! I did the svn checkout of the project, so I have available the =
various jonto projects on controlled vocabularies.
For each *_vocabulary project I view a common src module structure, =
where are included the *.ntriples and *.properties files, as well the =
*_Context.java and the *_Parser.java. Are these the properties/rdf files =
and the two java interfaces you mention above? So, if it is right, =
should I replicate a similar project for my own vocabulary? A step by =
step description of the process, by  @Mateusz, could effectively help =
me. =20

2) with wordnet it is more tricky - JOnto uses JWNL library to handle =20
WordNet dictionary. I was always hoping to be able to use other =20
national dictionaries - but we never had time to test it. However, the =20
infrastructure is there - and what I would suggest to do is to split =20
current wordnet module into an abstract/base dictionary module and =20
implementation modules, e.g., for wordnet. Depending on how much time =20
Mateusz can contribute to the either we can do that or your team.

An initial contribution from Matzeus could be the provision of some =
guidelines for splitting the wordnet module.

3) Answer to this question I leave to Mariusz, Maciej, and MarcOnt =20
team :)

Hope it was useful,

Yes, it was useful enough!=20
However my issue about metadata localization would extend the problem of =
the simple addition of new user dictionaries, towards a more large =
problem of managing simultaneously, as synonyms,  words with the same =
concept but in different language (ex. the English word "apple", and the =
correspondent Italian word  "mela"). I think this is  one of the main =
problems of effective social inter-language indexing/bookmarking in =
shared digital libraries.=20

Giuseppe

Cheers,

S.
