Abstract

A data query system including a first storage medium including a data schema having a data schema query language associated therewith, a second storage medium including an ontology model including classes and properties, the ontology model having an ontology query language associated therewith, wherein constructs of the database schema are mapped to corresponding classes, properties or compositions of properties of the ontology model, and an ontology query processor generating a query expressed in the data schema query language corresponding to a specified query expressed in the ontology query language. A method is also described and claimed.

Claims

1-92. -92. (canceled)

93. An ontology query system, comprising:

a storage medium providing an ontology model including classes and properties; and

a query builder generating an ontology query, the ontology query including a first clause indicating at least one subject class to which the query applies, and a second clause indicating at least one property or composition of properties defined on the at least one subject class, values of which are to be displayed.

94. The ontology query system of claim 93 wherein the ontology query includes a third clause indicating at least one condition that must be satisfied by values of properties or compositions of properties defined on the at least one subject class.

95. A method for querying ontological data, comprising:

providing an ontology model including classes and properties; and

generating an ontology query, the ontology query including a first clause indicating at least one subject class to which the query applies, and a second clause indicating at least one property or composition of properties defined on the at least one subject class, values of which are to be displayed.

96. The method of claim 95 wherein the ontology query includes a third clause indicating at least one condition that must be satisfied by values of properties or compositions of properties defined on the at least one subject class.

97-157. -157. (canceled)

158. A computer readable medium (CRM) containing executable computer program instructions which, when executed on a processing system, cause the processing system to perform a method for querying ontological data, comprising:

storing an ontology model including classes and properties; and

generating an ontology query, the ontology query including a first clause indicating at least one subject class to which the query applies, and a second clause indicating at least one property or composition of properties defined on the at least one subject class, values of which are to be displayed.

159. The CRM of claim 158 wherein the ontology query includes a third clause indicating at least one condition that must be satisfied by values of properties or compositions of properties defined on the at least one subject class.
