rdf - How can I use OWL Import with relative paths? -

-

in owl file, import many other files like:

<owl:imports rdf:resource="file:/home/noor/downloads/bbc/anatidae.rdf"/> <owl:imports rdf:resource="file:/home/noor/downloads/bbc/animal.rdf"/> <owl:imports rdf:resource="file:/home/noor/downloads/bbc/bird.rdf"/> <owl:imports rdf:resource="file:/home/noor/downloads/bbc/chordate.rdf"/> <owl:imports rdf:resource="file:/home/noor/downloads/bbc/kingdom.rdf"/> <owl:imports rdf:resource="file:/home/noor/downloads/bbc/mammal.rdf"/>

but i'm not able manage relative paths; these failing:

<owl:imports rdf:resource="file:anatidae.rdf"/> <owl:imports rdf:resource="file:./anatidae.rdf"/>

how can relative paths?

imports supposed point uris rather local files, therefore tools not support yet import local assets. in order handle local files, have following solutions:

  • a quick fix expose rdf via local web server , access them (e.g. <owl:imports rdf:resource="http://localhost/chordate.rdf"/>).

  • if using protege open owl file, can configure mapping between actual files , import iri in active ontology --> import ontology tab.

  • last solution, if work brain can load files 1 one without dealing owl:imports, example:

    brain brain = new brain();

    brain.learn("/home/noor/downloads/bbc/bird.rdf");

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
