An apparatus has a processor and a memory connected to the processor. The memory stores instructions executed by the processor to receive a relational query at a semi-structured document database. An access permissions index is looked-up for available documents for a user submitting the relational query. The relational query is resolved against relational schema within a relational schema index for the available documents to produce secure relational query results. The secure relational query results are supplied.

Apparatus and method for supplying secure relational query results from a semi-structured document database

A server includes a triple processor with instructions executed by a processor to receive an input document, read and store document restrictions for the input document, specify a first triple permutation, and produce for each triple in the input document a record of the triple in accordance with the first triple permutation and the position of the triple in the document. The server also includes a query processor with instructions executed by a processor to receive a query, match components of the query to triples in a triple repository to form initial triples, remove triples from the initial triples in accordance with document restrictions associated with the triples to form final triples, and return the final triples.
