XML (eXtensible Markup Language) has emerged and is being gradually accepted as the standard for data interchange over the Internet. Since most data is currently stored in relational database systems, the problem of converting relational data into XML assumes special significance. Many researchers have already done some accomplishments in this direction. They mainly focus on finding XML schema ...

Computational science communities are generating an ever-increasing volume of data products which are tracked and cataloged using metadata communicated via one or more community XML schemas. We propose a hybrid approach to storing metadata in a relational database that draws heuristics from computational science discovery, and show that the approach outperforms the well known inlining approach....

In support of the Board’s duty to conduct monetary policy for the United States, the research divisions at the Federal Reserve Board use a variety of time series data for both research and forecasting. The collection, maintenance, and upkeep of more than 50,000 time series from more than sixty sources in a central location are daunting tasks; documenting the metadata for the compilation and use...

The organised storage of spectral data described by according metadata is important for long term use and data sharing with other scientists. The recently redesigned SPECCHIO system acts as a repository for spectral field campaign and reference signatures. An analysis of metadata space has resulted in a non-redundant relational data model and efficient graphical user interfaces with underlying ...

In this paper we present the approach for creating semantic metadata from relational database data. When building ontology-based information systems, it is often needed to convert or replicate data from existing information systems (such as databases) to the ontology based information systems, if we want the ontology-based systems to work with real data. RDB2Onto tool converts selected data fro...

You can create source models from your relational source schema data of your metadata to be required in order to convert datatypes or to interpret your metadata. As with Designer's JDBC, Salesforce and WSDL importers, the XML File. Editing and validation support for XML Schema, Relax NG, NVDL scripts, Browse, edit, or query using XQuery and SQL with native XML or relational oXygen includes a to...

The imperative demand on the description of semantic metadata and the processing of real-time data presents unique challenge to Grid Metadata Service. Grid Monitoring Architecture (GMA), which is a framework for dynamic data management, is limited by its conventional interface of relational database and therefore fails to address the problem of interoperability. Faced with the problem of metada...
