Method and system for managing versioned structured documents in a database

摘要

A method for processing a query for a versioned structured document includes providing vNodes representing objects of at least one version of a structured document. Each vNode includes versioning information associated with a version(s) of the structured document. A query for a version(s) of the structured document is received. The query includes a vFunction having an argument(s) relating to versioning information associated with versions of the structured document. In response to receiving the query, a first vNode is identified that represents a first object in at least one version of the structured document and that includes versioning information satisfying the query. The first vNode is then used to determine a version(s) of the structured document that satisfies the query.
