Nina, I am trying to get a list of Ambit datasets for ToxCreate upload, using the SPARQL Query: PREFIX ot:<http://www.opentox.org/api/1.1#> PREFIX ota:<http://www.opentox.org/algorithms.owl#> PREFIX owl:<http://www.w3.org/2002/07/owl#> PREFIX dc:<http://purl.org/dc/elements/1.1/> PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> PREFIX rdf:<http://www.w3.org/1999/02/22-rdf-syntax-ns#> PREFIX otee:<http://www.opentox.org/echaEndpoints.owl#> PREFIX toxcast:<http://www.opentox.org/toxcast.owl#> select * where { ?endpoint rdfs:subClassOf otee:HumanHealthEffects. ?feature rdf:type ot:Feature. ?feature dc:title ?title. ?feature ot:hasSource ?src. ?feature owl:sameAs ?endpoint. ?src rdf:type ot:Dataset. } Which gives 0 results. If I ommit "?src rdf:type ot:Dataset." I can get a few features, most of the having a model as source (a few of them have an algorithm as source which I find strange). As a simple query with ?feature rdf:type ot:Feature. ?feature ot:hasSource ?src. ?src rdf:type ot:Dataset. gives also 0 results, I suspect that there are no dataset features in the ontology service. Is that true? What would be an alternative way to search for AMBIT datasets (and prediction_features), that are suitable for model building? Thanks! Christoph
