System and method to customize metadata for different users running on the same infrastructure

A method for retrieving data comprising:

• storing, in a meta-data repository, at least one meta-data item belonging to each of an element type and a relationship type meta-data;
• storing at least one data item in a data repository;
• capturing a relationship between the at least one meta-data item and a data item including a context in which the said relationship was generated;
• extracting, from data items stored in said data repository, said meta-data items;
• aggregating data and meta-data items and relationships thereof across one or more users in a structured file format;
• parsing the structured file format to extract data representing concepts, and to extract relationships;
• using a profile editor tool to permit a user, via a connected user device, to select relationships from the extracted relationships, the selected relationships being relationships that the user wants to consider during data queries;
• recording said user's selections as a profile for that user;
• retrieving, in response to a user query comprising at least requested data items, relevant data items by parsing said user profile to dynamically determine kinds of relationships a user wants to consider, and obtaining relevant relationships based on said user profile and said requested data items, wherein a selection of meta-data used in the retrieving is determined according to said user profile and the captured context information,
• wherein a processor unit runs a program to execute one or more of said storing, capturing, using and retrieving;
• wherein the selection of meta-data further includes contextual information about the retrieval query;
• and
• wherein the contextual information about the retrieval query further includes a description of when the query was generated.

A computer program product for retrieving data, the computer program product comprising:

• a storage device readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:
• storing, in a meta-data repository, at least one meta-data item belonging to each of an element type and a relationship type meta-data;
• storing at least one data item in a data repository;
• capturing a relationship between the at least one meta-data item and a data item including a context in which the said relationship was generated;
• extracting, from data items stored in said data repository, said metadata meta-data items;
• aggregating data and meta-data items and relationships thereof across one or more users in a structured file format;
• parsing the structured file format to extract data representing concepts, and to extract relationships;
• using a profile editor tool to permit a user, via a connected user device, to select relationships from the extracted relationships, the selected relationships being relationships that the user wants to consider during data queries;
• recording said user's selections as a profile for that user;
• retrieving, in response to a user query comprising at least requested data items, relevant data items by parsing said user profile to dynamically determine kinds of relationships a user wants to consider, and obtaining relevant relationships based on said user profile and, said requested data items, wherein a selection of meta-data used in the retrieving is determined according to said user profile and the captured context information,
• wherein a processor unit runs a program to execute one or more of said storing, capturing, using and retrieving;
• wherein the selection of meta-data further includes contextual information about the retrieval query;
• and
• wherein the contextual information about the retrieval query further includes a description of when the query was generated.
