摘要： 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.

摘要： The present invention provides an effective method for migrating the system services on which applications depend, rather than all of the system services, from a source OS platform to a target platform, in order to provide a suitable and consistent environment for the applications, while reducing the cost of the migration. The migration method further classifies the configurations of system services on different platforms into common configurations and specific configurations to accelerate the determination of the source of a migration error.

摘要： A method, system and computer program product is disclosed for supporting role-based access control in a collaborative environment, wherein pluralities of users work together in a collaborative process using a software system. The method comprises componentizing the software system into a multitude of software components, and limiting access to specific software components to certain users based on roles assigned to the users as defined by a run-time state of the collaborative process. The set of components that a user can access is dynamic, that set can change based on the “context” or the step where the user is in a collaborative workflow/process. Thus, in comparison with traditional access control mechanisms, an embodiment of the invention combines three different elements: a) the set of components that comprise the application is partitioned in such a way as to make componentized role-based access control feasible, b) a method for specifying inter-component dependencies to enable role-based groups, and c) enabling the modification of the access privileges based on contextual information from a collaborative process.
