Scott, I used the import feature, but it did not create an OWL file correspoding to the Excel file.
I had to add the <?rdf:RDF> tag to the end of the file to get it to open and when I did, there was no import history so I could not unimport. I sent the file to Holger. I have since rebuilt the ontology using a different approach. I tried using the Equivalent Class to show the OWL construct UnionOf (as oper TopBraid instuctions), but I do not like the results so I have to go back using Object Properties to describe the relationships. The Union Of is good for building a hierarchy in which a query (object property) is not needed. I am building an ontology for a financial database and queries are important.
