US Patent 11574070 Application specific schema extensions for a hierarchical data structure

A schema for a hierarchical data structure may include application specific extensions to the schema applied to a hierarchical data structure. Class may be added to the schema by individual applications granted access to a hierarchical data structure. When an access request for an object of the hierarchical data structure is received, the class may be identified in the schema and applied to process the access request to the object. Different classes may be added by different applications without disrupting the utilization of the schema for accessing the hierarchical data structure of other applications.
