12. When you can’t find your ontologies in Swoogle, it may be the case that your ontologies are not indexed by swoogle yet. Please submit it and increase its visibility. From site map When your query fails Demo 7 Submit URL for focused crawler

A tree survey A tree survey consists of:  a non-exhaustive list of the species that exist in a particular area.  data about each observed individual (e.g. diameter at chest height, picture, etc.) The metadata for each survey:  location;  Creator;  Date, time;

The evolution of Survey ontology The survey instance file drive the development of Survey ontology  (v1) http://daml.umbc.edu/ontologies/webofbelief/1.1/s urvey.rdf http://daml.umbc.edu/ontologies/webofbelief/1.1/s urvey.rdf Most terms are created by self.  (v2) http://spire.umbc.edu/ontologies/survey.rdfhttp://spire.umbc.edu/ontologies/survey.rdf More reused terms Longitude and latitude may be borrowed in future.

19. @ SwoogleSwoogle SwoogleSwoogle Some Issues Inference complexity – OWL full or OWL DL? Ontology instance in Instance document InverseFunctionalProperty  foaf:mbox, foaf:mbox_sha1sum has range xsd:anyURL and rdfs:Literal repectively, so it is DatatypeProperty. However, it cannot be InverseFunctionalProperty. Add class foaf:Mbox  tagnumber placeName, place_name
