An effective means for building an interlocking trees datastore from multiple data sources that contained within the datastore the knowledge of the origin of the data was needed, and is thus described herein. Should it be desired or necessary to identify the different sources of data within the Kstore data structure, the present invention teaches how an additional field for the origin of the data is created, how the origin of the data is stored in that newly created field, and how the interlocking trees data store takes that field and creates nodes within the structure, therefore embedding the origin information within the knowledge contained in the Kstore data structure.
