In my example file I have both T-Boxes and A-Boxes. An A-Box example in the file is “Bridge_1”. (which is an individual of the A-box “Bridge” in the same file).
What I would like to do is to be able to get the data via: "http://dbpedia.org/resource/<http://dbpedia.org/resource/Switzerland>Bridge_1” So what name space (baseURI) should I define for my file to be able to do that? Guess I wrongly thought it has to be: "http://dbpedia.org/resource/<http://dbpedia.org/resource/Switzerland>” From: Fabian Cretton [mailto:fabian.cret...@hevs.ch] Sent: vrijdag 10 oktober 2014 10:09 To: users@marmotta.apache.org Subject: RE: Rép. : Re: How to use Marmotta for Linked data publishing ? Michel, Actually I am not really sure what you try to achieve. We talk about Linked Data publishing, right ? So making data from the store accessible via their URI, with content negociation. I would make a distinction between the ontology (let say T-Box) and the data (A-Box). As in DBPedia, both have different prefixes: "http://dbpedia.org/resource/<http://dbpedia.org/resource/Switzerland>" for the A-Box and for instance "http://dbpedia.org/ontology/"; for the T-Box. I don't think Marmotta is intended to publich the T-Box on "/resource" eventhoug it is feasible, but it would be misleading I think. Also, it seems reasonable to publish a T-Box on a "hash URI", as people will want to access the all T-Box and not just one resource. I think you don't want to assert this: http://localhost:8080/marmotta/resource rdf:type owl:Ontology ; I don't know how Marmotta handles that, but it seems a wrong assertion. Taking a much simple exemple, you can declare: <http://localhost:8080/resource/tstLDRes> a <http://xmlns.com/foaf/0.1/Person>; rdfs:label "A resource to test Marmotta's Linked Data publishing" . And then have a "linked data" access to: http://localhost:8080/resource/tstLDRes If we wanted to handle T-Box, we could create a new Marmotta module, for instance on a "/ontology" web service. That was suggested in the discutions by the Team, and that would be not too complicated to implement. As an example, we did a little demonstrator for eGov projects, where we use pubby to publish the A-Box, as for instance: http://logd.ch/eCH-0070/id/10 (here we used 'id' instead of 'resource', as it is also often used, and shorter) And we did use a tool called "LODE" to publish the .html version of the T-Box, as: http://logd.ch/voc/service Hope this helps Fabian >>> "Bohms, H.M.
