Virtual Fly Brain Images (VFB)
The VFB query system relies on representation of data/knowledge in OWL. Central to this a representation of Drosophila neuro-anatomy in the Drosophila anatomy ontology. The anatomical structures depicted in images displayed on VFB are represented as a KnowledgeBase of OWL individuals, which are classified (typed) using OWL class expressions referencing the anatomy ontology. When this KnowledgeBase of individuals is combined with the ontology, a reasoner can be used to classify and query for anatomical structures depicted in the images on VFB.
You can run queries against the VFB OWL server using the python package vfb-connect or directly via our owlery server endpoint http://owl.virtualflybrain.org/kbs/vfb. Details of the Owlery rest API can be found here.
