Abstract: A computer implemented method of representing real numbers of positive and negative sign as a character string such that the a lexicographical ordering of the character string matches the numeric ordering of the real numbers. In the method, a real number is expressed as at least one whole number followed by at least one fractional number, times a predetermined base to a whole number exponent. In one embodiment the representation is formed by concatenating, in a predetermined order: a representation of the sign of the real number; a representation of the numeric ordering responsive to the exponent; a representation of the exponent; and a representation of the whole numbers followed by a representation of the at least one fractional number.

Abstract: A system and method for internationalizing user interfaces associated with Web pages and other software and especially interactive web pages. Translation files are stored in a server and transmitted to clients as needed. Preferably strings are arranged in a tree so that the client can request specific subtrees. The user interface responds dynamically to a change in the user's language preference, without requiring a restart of the application.

Abstract: An efficient representation of a changing directed acyclic graph (DAG) in a computer system. A representation of all the paths in the DAG are stored in memory and kept synchronized with the representation of the DAG which may change over time. This allows some important queries to be performed very quickly such as finding all the descendants of a node.

Abstract: An enterprise application system including a run-time transformation server, and a message broker for routing and transforming data in the form of messages between a source application and a target application, including a plug-in for preparing requests to the run-time transformation server and for processing responses from the run-time transformation server. A method is also described and claimed.

Abstract: A distributed ontology system including a central computer comprising a global ontology directory, a plurality of ontology server computers, each including a repository of class and relation definitions, and a server for responding to queries relating to class and relation definitions in the repository, and a computer network connecting the central computer with the plurality of ontology server computers. A method is also described and claimed.

Abstract: An instance browser including a repository of class and relation definitions, a server for responding to queries relating to class and relation definitions in the repository, and a graphical user interface including icons for representing instances of classes. A method is also described and claimed.

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 system for managing and querying a plurality of data sources, including an interface to a plurality of inter-related data sources of diverse types, each of the plurality of data sources having a schema that describes its data structure, a schema generator communicating with the interface, for generating a federated schema that describes the structures of the plurality of data sources and their inter-relationships, and for modifying the federated schema over time as the plurality of data sources undergo changes, and a query generator communicating with the schema generator, for generating a query for the federated schema. 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 method for transforming data from one data schema to another including receiving a source data schema and a target data schema, mapping the source data schema into an ontology model, mapping the target data schema into the ontology model, and deriving a transformation for transforming data conforming to the source data schema into data conforming to the target data schema, using the ontology model. A system is also described and claimed.

Abstract: A method for mapping data schemas into an ontology model, including providing an ontology model including classes and properties of classes, providing a data schema, identifying a primary data construct within the data schema, identifying a secondary data construct within the primary data construct, mapping the primary data construct to a corresponding class of the ontology model, and mapping the secondary data construct to a property of the corresponding class of the ontology model. A system and a computer readable storage medium are also described and claimed.

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.
