Abstract: A metadata management system for importing, integrating and federating metadata, including a configurable metamodel, a metadata repository for storing metadata whose structure reflects the metamodel, at least one external metadata source, which is able to persist metadata in accordance with the structure of a meta-schema, a mapping module for mapping the meta-schema to the metamodel, and a transformation module, operatively coupled to the metadata mapping module, for translating specific metadata from the at least one external metadata source to the metadata repository, for use in import, export or synchronization of metadata between the external metadata source and the metadata repository. A method and a computer-readable storage medium are also described.

Abstract: A method for determining the complexity of an enterprise information resource management system, the enterprise information resource management system being used to contain an ontology into which a plurality of enterprise data assets are mapped, the ontology including a plurality of model constructs, the enterprise data assets including a plurality of assets constructs, and the mappings between the data assets and the ontology including a plurality of mapping constructs, including receiving (i) a number of distinct asset constructs, denoted by CASSET, (ii) a number of distinct mapping constructs, denoted by CMAPPING, and (iii) a number of distinct model constructs, denoted by CMODEL, evaluating a metric of complexity, denoted by M, for an enterprise information resource management system having a capacity corresponding to CASSET, CMAPPING and CMODEL, according to a formula M=ƒ(CASSET, CMAPPING, CMODEL, X), where ƒ is a real-valued function of three or more real-valued parameters and X denotes optional additi

Abstract: A portal for interactively viewing enterprise metadata, including a memory for storing a data structure in the form of a graph, with nodes representing asset metadata for enterprise data assets and edges representing relationships between asset metadata, a path finder for generating at least one path within the graph satisfying prescribed constraints, and a report generator for generating a report about the graph, based on paths generated by the path finder. A method and computer readable storage medium are also described and claimed.
