Hi, (I'm new to Zope and Plone, so don't hesitate to indicate me a more appropriate mailing-list if necessary) I am curently looking for a library (idealy, ready-for-Plone3.x-Zope2.10) allowing the creation and management of a thesaurus. Our requirements are the following: - creation of our own thesaurus (that is, terms AND relations between terms), and indexing (and retrieving) documents with terms defined in our thesaurus, - "thesauraus management facilities", such as batch editing of content items (e.g. for all documents indexed by keyword "A" and "B", replace keywords "A" and "B" by keyword "C"). - user-friendly interface. This could a be tree-like structure (with - ideally - several levels of indexing), such as: Shape - TS: Square + TS: Triangle - TS: Scalene triangle + TS: Equilateral triangle - [...] - [...] - [...] - [...] After some - basic - searches, it appears that there are not many thesaurus management developed for Plone/Zope (and maybe even in python) yet, but as I'm new to Zope-Plone, I may be mistaking: - PloneOntology looked interesting (http://plone.org/products/ploneontology) but is it still maintened (no release for one year)? - icSemantic / pyThesaurus (http://plone.org/products/icsemantic-thesaurus http://www.platecom.com/) looks promising but there isn't much documentation and the website is only in Spanish for the moment). - Tabajara (http://plone.org/products/tabajara) looks like a dead project (only works for Plone 2.1??). - I don't think Portal Taxonomy (http://plone.org/products/portal_taxonomy) or AT Vocabulary Manager (http://plone.org/products/atvocabularymanager) are suited for thesaurus - pyWordNet (http://osteele.com/projects/pywordnet/index.html) appears to be more a back-end to WordNet thesaurus than a thesaurus mangement tool. - so far, TextIndexNG3 (http://www.zopyx.de/projects/TextIndexNG3) looks the most promising, event if it doesn't appear to offer thesaurus management tools yet... What do you think of it and/or is there already a discussion on this topic? Thank you in advance, Benjamin Michiels -- Software AG Benelux
