I would like to represent my concepts scheme using SKOS, and then serialise it in RDF. Is there tools for creating such a representation? SKOSed with Protégé4-beta does not offer all classes of SKOS as they defined in W3C like Is their any other tools to do such a task? |

For editing and using SKOS models, try TopBraid Composer. There are various tools for defining and using SKOS - displaying broader/narrow relations in a tree view, displaying nodes by skos:prefLabel, constraints for SKOS data quality, etc. Also see the Enterprise Vocabulary Network (EVN), which is Web-based end user product that works with SKOS models out-of-the-box, and with a couple of small setup steps will support concurrent multi-user editing with audit trails. This includes version control and provenance features necessary for collaborative ontology editing. You can design models and evaluate EVN with TBC-ME (free trial), and the general SKOS modeling tools are available in TBC-Free. sorry for being pedantic, but an "SKOS ontology" is the specification of SKOS standard. Specific data sets with instances of skos:Concept, skos:Scheme etc. should never be called ontology but "terminology", "knowledge organization scheme (KOS)", "classification", "thesaurus" etc. It's ironic: KOS are created to avoid terminology confusion :-) 1
Not sure I agree, particularly with "never", as SKOS vocabulary terms can certainly be used in an ontology. I also don't know what the broader term for "terminology, knowledge organization scheme (KOS), classification, thesaurus etc." (from http://www.w3.org/2004/02/skos/intro) would be, so I used "model". |

I think probably the best tool out there for managing SKOS classifications is PoolParty. It is not free, but you can give it a try. TemaTres Vocabulary Server has the option of SKOS export, so it might be good enough for your purposes. Thank you for a response, I want to know if you are already used Skosed? So, could you show me, if you would, how can I create collections using it? Thanks. 1
As I said, I don't have much experience with Protégé, so I can't really advise you. I know there were some problems with SKOS collections support (http://code.google.com/p/skoseditor/issues/detail?id=4#c1) that should be fixed in newer versions of Protégé. Other than that I would recommend you using something else than Protégé (http://www.semanticoverflow.com/questions/2281/convenient-input-of-individuals-does-protege-4-really-have-to-ignore-this-are/2289#2289). Thanks, I wish you Happy new year |

iQvoc is another tool. It was presented at the Semantic Scripting Workshop 2010 (see the paper linked at the workshop page) as "open source SKOS-XL vocabulary management tool developed by the Federal Environment Agency, Germany, and innoQ Deutschland GmbH", written in Ruby and JavaScript (jQuery). There is a German product page but I have not found the promised open source software, which is claimed to be licensed under Apache 2.0. The paper also mentions PoolParty, MMI Ontology Registry, Neologism, and OntoWiki as alternatives. 1
The source code for the open source software iQvoc is on innoQ's repository on Github. It's a Ruby on Rails application and you can download and install it yourself. |

A less known web-based tool created for German museums is xTree (see German description). There is a test account at http://xtree-test.digicult-nord.de/ |
