Hi all Talked yesterday directly about that with Andrea. After some testing it looked like that the Solr Index somehow had not contained the expected data (provided by the defaultdata bundle).

In this case only the ID is store in the Entityhub. If the Entity would not be present, than the server would return a 404 instead of this request. Currently requests always return the Entity and the Metadata. In future [1] it will be also possible to request only the data or the metadata. > "metadata": { > "id": "http:\/\/dbpedia.org\/resource\/Bob_Marley.meta", > "http:\/\/www.iks-project.eu\/ontology\/rick\/model\/isChached": [{ > "type": "value", > "value": "true" > }], > "http:\/\/www.iks-project.eu\/ontology\/rick\/model\/about": [{ > "type": "reference", > "value": "http:\/\/dbpedia.org\/resource\/Bob_Marley" > }], > "http:\/\/www.w3.org\/1999\/02\/22-rdf-syntax-ns#type": [{ > "type": "reference", > "value": "http:\/\/xmlns.com\/foaf\/0.1\/Document" > }] Metadata are created on the fly for Entities of referenced sites. They allow e.g. to retrieve if the returned data are the locally cached one. For Entities managed by the Entityhub this metadata will also include the state, creation data and possible additional metadata directly set via the RESTful interface. > } > > Is it still possible to fetch the graph as it is on the LOD dataset via > REST service? > Yes. In this case by using the following CURL command (assuming the Stanbol is running on localhost:8080 curl -H "Accept: application/rdf+xml" http://localhost:8080/entityhub/site/dbpedia/entity?id=http://dbpedia.org/resource/Bob_Marley The same result should also be return when requesting the entity via the ReferencedSiteManager curl -H "Accept: application/rdf+xml" http://localhost:8080/entityhub/sites/entity?id=http://dbpedia.org/resource/Bob_Marley best Rupert Westenthaler -- | Rupert Westenthaler [email protected] | Bodenlehenstraße 11 ++43-699-11108907 | A-5500 Bischofshofen
