我正致力于两个本体之间的本体对话。我在本地应用jena / pellet平台,并尽可能地应用sparql规则。对于插入,这是成功的,对于删除它不是,无论我尝试什么。这引发了一个问题,即jena / pellet是否支持sparql删除。请指教!
请在下面找到相关的代码段。首先是代码,然后是sparql DELETE查询。
public void executeDelete(String mySparqlFile, OntModel o ) {
UpdateRequest updateObj = null;
UpdateProcessor up = null;
GraphStore graphStore = GraphStoreFactory.create();
graphStore.setDefaultGraph( o.getGraph() );
updateObj = UpdateFactory.read( mySparqlFile );
up = UpdateExecutionFactory.create(updateObj, graphStore);
up.execute();
}
public static void main() {
static OntModel ontModel = ModelFactory.createOntologyModel(PelletReasonerFactory.THE_SPEC, rawModel);
static OntModel stanfordModel = ModelFactory.createOntologyModel(PelletReasonerFactory.THE_SPEC);
stanfordModel.read("path/to/modelA.owl");
ontModel.addSubModel(stanfordModel);
executeDelete("path/to/delQuery.sparql", ontModel);
}
文件" delQuery.sparql"
