Imagine you are querying a data source via an SPARQL endpoint and you want to know if the underlying representation of this data source is OWL or RDF/XML. Is there anyway that you would be able to do that via a SPARQL query? My personal line of thought was to write a query that uses one of the OWL properties and see if that returns any result, however the disadvantage of using such approach is that if you use an OWL property that doesn't appear in the data source even if the underlying representation is OWL you would not get a response. The assumption here is that your don't have access to the

I'm using booth Sesame .wars in Tomcat 7 on OS X 10.8, but now it doesn't work any more. I set up a new Tomcat with two new Sesame .war but now it uses the old repository. Where are these stored? (Couldn't add a new Repo or delete the old one). Sesame Server by default stores its configuration data and database files in %APPDATA%\Aduna on Windows, $HOME/.aduna on Linux, and $HOME/Library/Application Support/Aduna on Mac OS X. If you want a completely new install, simply delete this directory. See the Sesame manual for more info. Update you can check where your Sesame server installation stores

I want to use pellet reasoner with my Fuseki 2.3.1 First: I added Pellet reasoner to my config.ttl as this: ja:reasoner [ ja:reasonerClass "org.mindswap.pellet.jena.PelletReasonerFactory";] So now I have to add the jar for Pellet to fuseki This page explains how to add jars (not specificaly pellete) to fuseki https://jena.apache.org/documentation/permissions/example.html So I commet this line exec $JAVA $JVM_ARGS -jar "$JAR" "$@" and I uncommet this line java $JVM_ARGS -cp "$JAR:$APPJAR" org.apache.jena.fuseki.cmd.FusekiCmd "$@" and uncomment the line that starts with APPJAR= now I still need

I have recently started learning Web Ontology Language (OWL). I want to define a DataProperty with my own defined range of value. Consider the following property: <owl:DatatypeProperty rdf:ID="myProperty"> <rdfs:domain rdf:resource="#MyDomain"/> <rdfs:range rdf:resource="http://www.w3.org/2001/XMLSchema#double"/> </owl:DatatypeProperty> The property has the range of double value but I want to restrict the range in order to make my property to accept only double values between 0 and 1. I would be very grateful if you guide me how to define my own ranges for data properties. Here you go (in

I want to load an OWL file before executing other (visualisation-)scripts. To do this I tried everything from $(document).ready to function visualize (file) { if (!file) {setTimeout(visualize(file), 2000)} else {jQuery(function($){visFeaturePool.init(file)})}} I think it has to be possible with the setTimeout but that isn't working. I throws the error: Uncaught RangeError: Maximum call stack size exceeded, so it doesn't wait, it just recalls the visualize function untill the stack is full. Does anybody know what I am doing wrong? Thanks! Instead of // #1 setTimeout(visualize(file), 2000); you

I want to import some classes in Protege from different ontologies to my ontology. For example, I need the classes foaf:Person , org:Site , vcard:Organization , and many more. I don't want to create them by myself (and modifying their IRI). When I did import the whole ontology (Schema.org, vCard, FOAF, …), I had many elements that I don't need. Is there any way to do it? — Have you looked at this thread: protege-project.136.n4.nabble.com/… — I tried to use it, but it didn't work. There are subtle moments, especially on step 5. Open your target ontology. Open the source ontology in the same

What is the difference between EquivalentClass and SubClass of? While reading through OWL primer, i find the tutorial uses SubClassOf a lot to declare a new class, as follows SubClassOf( :Teenager DataSomeValuesFrom( :hasAge DatatypeRestriction( xsd:integer xsd:minExclusive "12"^^xsd:integer xsd:maxInclusive "19"^^xsd:integer ) ) ) Can I write EquivalentClass( :Teenager DataSomeValuesFrom( :hasAge DatatypeRestriction( xsd:integer xsd:minExclusive "12"^^xsd:integer xsd:maxInclusive "19"^^xsd:integer ) ) ) instead? When stating that A is a subclass of B , this restricts A to necessarily inherit
