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

1-110. -110. (canceled)

111. An ontology modeling system stored in a computer readable medium, the ontology modeling system comprising:

at least one data construct for container classes for modeling sets, bags and lists;

at least one data construct for modeling multi-valued properties whose targets are said container classes; and

at least one data construct for imposing constraints on said multi-valued properties.

112. The ontology modeling system of claim 111 further comprising at least one data construct for assigning a minimum number of elements and a maximum number of elements to said multi-valued properties.
