Method, system, and program for translating a class schema in a source language to a target language

Abstract: Provided are a computer implemented method, system, and program for translating a class schema in a source language to a target language. Class element definitions in a source file in the source language are received. The definitions of the class elements define instances of metadata types providing metadata for the class elements. Statements in the target language are generated to implement class elements defined in the source file. Statements are generated in the target language to define metadata elements for metadata types. For each metadata data type instance defined with one class element in the source file, at least one statement is generated in the target language to associate the metadata element generated for the metadata type with the implementation of the class element corresponding to the class element defined with the metadata type instance in the source file.

Method and system for providing uniform access to heterogeneous information

Abstract: Our invention is a system and methodology for integrating heterogeneous information in a distributed environment by encapsulating data about existing and new information into objects (16). The process of encapsulating the information requires extracting from the information metadata. Creating from the metadata, a database (30), where the metadata is grouped into objects (26) and groups of objects (28) which are logically associated into collections (28). This database of object and collections is instantiated into runtime memory of a server (22), organized into repositories (24) of objects (20) and collections (28). A user (12) seeking access to the information would then, using an HTTP compliant browser (20), access the server (22) to access the information through the objects (26) created and stored in the server.

System and method for semantics driven data processing

Abstract: The present invention provides a system, method and computer program for metadata conduit driven data integration in which data from one or more data sources is integrated using a pre-processor (110), a modeler (106), a metadata repository (108), a virtual data access engine and a web portal (112), wherein an integration server (102) consumes the metadata stored in the repository to direct queries to data sources and aggregate data and provide functional views of this data to the information consumers. The metadata stored in the repository (108) also drives generations of platform independent applications used in the life sciences domain (research and/or drug development and diagnostics).

Data and Metadata Collections for Scientific Applications

Abstract: The internet has provided a means to share scientific data across groups and disciplines for integrated research extending beyond the local computing environment But the organization and curation of data pose challenges due to their sensitive nature (where data needs to be protected from unauthorized usage) as well as their heterogeneity and large volume, both in size and number Moreover, the importance of metadata is coming to the fore, as a means of not only discovering datasets of interest but also for organizational purposes SDSC has developed data management systems to facilitate use of published digital objects The associated infrastructure includes persistent archives for managing technology evolution, data handling systems for collection-based access to data, collection management systems for organizing information catalogs, digital library services for manipulating data sets, and data grids for federating multiple collections The infrastructure components provide systems for digital object management, information management, and knowledge management We discuss examples of the application of the technology, including distributed collections and data grids for astronomical sky surveys, high energy physics data collections, ecology, and art image digital libraries

Automatically attaching semantic metadata to Web Services.

Abstract: Emerging Web standards promise a network of heterogeneous yet interoperable Web Services. Web Services would greatly simplify the development of many kinds of data integration and knowledge management applications. Unfortunately, this vision requires that services provide large amounts of semantic metadata “glue”. As a first step to automatically generating such metadata, we describe how machine learning and clustering techniques can be used to attach attach semantic metadata to Web forms and services.
