GeoSpatial properties and relationships

All, I have a requirement to associate geospatial geometries to resources and then be able to search for resources based on geospatial relationships such as intersects, near, etc. I would like to do this using jena, but not sure what has been done. If anyone has done this or has suggestions that

Should model.read emit addedStatements ?

I am trying to upgrade our application from Jen 2.7.3 to 2.11.0 It appears that in Jena 2.7.3 model.read(stream, null, "RDF/XML") fired a single ModelChangedListener.addedStatements whereas model.read(stream, null, "TTL") fired separate addedStatement events. Now in 2.11.0, both types of load em

RE: Writing big models to disk

Thanks a lot for the prompt answer, it works now. All I had to do was close the stream afterwards. The following code does it, using jena 2.10.1: BufferedWriter out = new BufferedWriter(new FileWriter("file.rdf"));resultModel.write(out, "N-TRIPLE");out.close(); Best,Nikos > Date: Tue, 29 Oct 201

Hi Milorad, I appreciate you introducing me to the service. Unfortunately, it did not solve the problem as I was asking for a SPARQL construct. Thanks! On Wed, Oct 30, 2013 at 6:37 PM, Coeus[TM] wrote: > Hi, > > May I seek for someone's help on how to construct a query for FundRef > RDFregis

Thanks for the answer , which is not surprising . This suggests new questions: - 1. would it be difficult to add this feature, and make timestamp available through the API ? - 2. is the order of triples insertion also preserved in SPARQL results, API SPO queries and other outputs ? 2013/10/30

Re: SPAM-HIGH: TDB record timestamp of triples?

No it does However since triples are stored in B+Tree based indexes there is an ordering to the triples within the internal storage so when tdbdump outputs the contents of the database the triples will be serialized out in that order. Rob On 30/10/2013 10:20, "Jean-Marc Vanel" wrote: >Hi > >Do

SPARQL and FundRef RDF Registry

Hi, May I seek for someone's help on how to construct a query for FundRef RDFregistry please. The idea is to simply search a funding source (e.g. National Science Foundation) by Id (e.g. http://dx.doi.org/10.13039/10001";>) and vice-versa. Dataset can be found at http://www.crossref.org/docs
