From martin.hepp at ebusiness-unibw.org Fri Jan 9 08:01:12 2009 From: martin.hepp at ebusiness-unibw.org (Martin Hepp (UniBW)) Date: Fri, 09 Jan 2009 08:01:12 +0100 Subject: [goodrelations] Introducing myself to the group In-Reply-To: References: Message-ID: <4966F638.7070801@ebusiness-unibw.org> Dear Alex: Welcome to the mailing list and the GoodRelations community. Please make sure you are using the new version of eClassOWL 5.1.4 from the following locations: a) eClassOWL 5.1.4 Products and Services Ontology (OWL): http://www.ebusiness-unibw.org/ontologies/eclass/5.1.4/ (Warning: The file is very large - 38.3 MB for RDF/XML and 71.8 MB for HTML) b) eClassOWL 5.1.4 Products and Services Ontology and documentation, compressed (OWL + HTML, zip): http://www.ebusiness-unibw.org/ontologies/eclass/5.1.4/eclass_514en.zip (4.7 MB) The version at http://www.heppnetz.de/projects/eclassowl/ is outdated and not fully compatible with GoodRelations. As for the structure of eClassOWL: This is determined by the class structure of the eClass standard, from which eClassOWL is derived by means of the algorithm explained in [1]. eClass is a broad, multi-industry initiative for providing classes and attributes for sourcing, mainly in the industrial sector. This is why parts of the class hierarchy may seem unsuitable for procurement in the commodity / B2C sector. Note that using GoodRelations does not require using eClassOWL, too. In fact. there are many scenarios in which other options are better, e.g. creating your own ontology for the types of products ( see http://www.heppnetz.de/projects/goodrelations/documentation/vocabulary-dev for instructions). You can also describe your articles just by textual labels and still benefit from GoodRelations - all the commercial and logistical details of the offering will then be fully machine-readable, while the search by product types will be a bit limited. But often, that will still be a good solution, in particular if your source data is not already preclassified according to eClass. Again, welcome to the crowd ;-) Best wishes Martin PS: As for Jena snippets, I don't have any at hand - but there should be plenty on the Web. You can also use http://www.ldodds.com/projects/twinkle/ If I remember correctly, you can also get the source code. As a first starter, though, I would look at the excellent Jena online doc. Another hint: When starting, make sure that you keep properly apart conceptual issues (OWL language, ...) and Jena. You should first understand the underlying SW concepts and specifications before thinking in Jena method calls etc. Alex Genadinik wrote: > Hi, > > I am a software engineer currently working on an eCommerce semantic > web project.
