Multi-source multi-tenant entitlement enforcing data repository and method of operation

An information processing apparatus including means for maintaining a multi-source multi-tenant data repository, wherein the means for maintaining comprises:

• means for forming said multi-source multi-tenant data repository to include information elements from a plurality of sources, describing at least one referred entity;
• means for annotating a plurality of elements from said information elements in the multi-source multi-tenant data repository with sourcing information;
• and
• means for maintaining information about entitlement of requesters to information elements based on said sourcing information.

A multi-source multi-tenant reference data repository, comprising:

• means for inputting into said repository information about business instrument information, corporate hierarchy information, corporate news information and other information from multiple sources;
• means for annotating changes to said business instrument information, corporate hierarchy information, corporate news information, and other information, and sources of each change;
• means for maintaining information about entitlement of requesters to obtain said business instrument information, corporate hierarchy information, corporate news information, and other information, based on entitlement to the sources and processes which have provided or modified this information;
• and
• means for responding to at least one request from at least one requester to return at least a subset of said business instrument information, corporate hierarchy information, corporate news information, and other information, based on requester-specified selection and sourcing preferences and subject to said entitlements.

A repository apparatus comprising:

• means for forming the repository with information element structures in place;
• means for inserting arriving information elements into a store of said the repository;
• means for annotating each information element with annotations describing evolutionary history of said each information element in forming an evolutionarily tracked source data tag for said each information element;
• means for maintaining source based entitlement information for authorized requesters of repository information and data sources to which each authorized requester is entitled;
• and
• means for employing said evolutionarily tracked source data tag together with source based entitlements in a process providing entitlement enforced controlled access to information included in the repository.

• annotating a plurality of said elements with sourcing information;
• and
• maintaining information about entitlement of requesters to information elements based on said sourcing information.
