Len,

The Protégé Frames metamodel is not a row and table kind of structure, so
SQL Like access models do not make much sense. XML and XPath are more
structurally similar than the relational model. 

There is a process available to convert a frames ontology to SQL tables
which may be what you are looking for. This page describes a a way to create
a SQL reporting database from the XML file that Protege can use as a
backend. This can be found at:

The Protégé Frames metamodel is not a row and table kind of structure, so
SQL- like access models do not make much sense. XML and XPath are more
structurally similar to frames than the relational model. Details of the
content differences, and another approach to converting a frames model to a
database, can be found at:

Greetings, 

Quick question: is there a tool (or third-party plug-in) that can be used to
query frame-based instances in a SQL-like fashion?

Thanks
