Hi Anja, hi Sebastian! Thanks for your reply. As I understand "transitive" means that dbprop:issn owl:equivalentProperty prism:issn when I state dbprop:issn owl:equivalentProperty bibo:issn because of bibo:issn owl:equivalentProperty prism:issn
So repetition is not necessary. As to your answer to question 1: I will create the classes rdfs:Literal and rdfs:Resource. But I don't understand why all the vocabularies are created again in the wiki. The Link in http://mappings.dbpedia.org/index.php/OntologyProperty:Zdb is now correct, but I will change it to rdfs:Literal.

Yes, I think so 2. There is a list somewhere. It is hardcoded...which is bad 3. I can not answer this, it might be a bug 4. what do you mean by repeatable? equivalentProperty is a transitive, symmetric and reflexive equivalence relation. http://de.wikipedia.org/wiki/%C3%84quivalenzrelation All the best, Sebastian On 03/06/2012 01:47 PM, Klee, Carsten wrote: > Hi all! > > Some questions concerning editing the dbpedia ontology properties in the > mappings wiki: > > 1. > What is the best practice to set the values for rdfs:domain, rdfs:range, > owl:equivalentProperty etc.? > For example http://mappings.dbpedia.org/index.php/OntologyProperty:Issn > I changed the range of this property to rdfs:Literal to make it compatible > with bibo:issn (as the owl:equivalentProperty). > Do I have to use the full URI http://www.w3.org/2000/01/rdf-schema#Literal or > do I have to create the class rdfs:Literal in the mappings wiki like > http://mappings.dbpedia.org/index.php/OntologyClass:Foaf:Person ? > > 2. > What prefixes are allowed in the ontology anyhow?
