[TYPO3-semantic] Tips for searching / creating #ontology

[Fabien Udriot]

Hi everyone!

* What tool / resource do you use for hunting down a specific Ontology?
   Let say, I am searching for an Ontology about "Government", what tip
   would I have for finding the suitable Ontology for my needs?

   I have spotted a Search Engine for Ontology but I am sure it exists other resources.
   http://swoogle.umbc.edu/index.php

   It seems there exists a list here:

* Creating its own Ontology, is it something common and recommended?
   Or should it be done at the latest if now suitable Ontology is to be found?


* What are the criteria to choose an Ontology? by popularity? by Search Engine support?


* Does it exist a centralized place where to advertise its own Ontology?
   I fear it does not exist much but perhaps, you know some on-going initiative about that.


* What format would you use to describe an Ontology? RDFS, OWL, OML?
   What are the purposes of each and pros and cons?

A few potential questions that we could put on our FAQ...

Cheers,

Fabien
