Patent number: 9286362Abstract: A metadata management system and method enables complex query searches by users, e.g., different users having different query needs, using the same infrastructure. For querying metadata, the metadata management system provides functionality for aggregating all the concepts (metadata items) and relationships of the metadata across one or more users in a common format; extracting concepts and storing them in a metadata store (e.g., a relational database); extracting relationships and modeling them in a standard semantic representation. The system and method further records users' different needs on relationships into user-specific configuration files. The system is configured for retrieving, in response to a user query, relevant data items by using the meta-data selectively. In one embodiment, a selection of meta-data used in the retrieving is determined according to captured context information.Type: GrantFiled: September 25, 2009Date of Patent: March 15, 2016Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Rohit M.
