Hi, I agree with Pat in that case, that it would just be easier not to put restrictions in the abstract rdf syntax at all, instead of complicating things all over the place. There are pragmatic reasons why sentences such as http://bblfish.net/#hjs name Henry . are not going to be

Re: National Identification Number URIs ( NIN URIs )

2010-03-09 Thread Bernhard Schandl
Peter, It is a good thing that the subject URI is an HTTP URI available from your server but that is only the start of the story. The rest of the story needs other servers to give your data more context. In your example the fact that there is a link can only be figured out using some

Hi Christoph, I.e. the reasoning in http://www.w3.org/2001/tag/doc/httpRange-14/2007-05-31/HttpRange-14#iddiv1138805816 (essentially the same as what you said above) is clear to me from a philosophical point of view, but not from a technical one. I'm taking a more pragmatic view here, as

SPARQL: restricting DESCRIBE queries

2009-09-07 Thread Bernhard Schandl
Hi, is there any way to limit the number of triples returned by a DESCRIBE query? The LIMIT clause of sparql obviously applies to the number of result bindings, but each result binding may lead to an arbitrary number of triples. Consider the following queries against dbpedia: SELECT

Hi, Unfortunately, I want to employ an RDFS reasoner AND use the foaf:holdsAccount to point to /non/Online Accounts. I can't use it because my /non/online Accounts WILL be interpreted as foaf:OnlineAccounts, which I want to be satisfiably false (but is provably true). Clearly. To fix

Dan, Yeah, my [4] is at my threshold of tolerance for chaos in a diagram. I wanted a way to show the core of the FOAF spec in a picture, so tried (despite similar concerns to those mentioned in this thread) the style of putting domain/range directly in an instance-like style. I think

Re: Visualization of domain and range

2009-06-25 Thread Bernhard Schandl
However many newbies to RDF and ontologies are confused by this, because the triple foaf:Agent foaf:holdsAccount foaf:OnlineAccount . is actually not contained in the ontology. What needs to be communicated is that: [ a foaf:Agent ] foaf:holdsAccount [ a foaf:OnlineAccount ] . instead.
