The XQuare project: open source information integration components based on XML and XQuery

XQuark changes its name for XQuare ! - September 10, 2005

Following the injunctions of a commercial brand from the sofware sector (the counterpart for success ?), XQuark decided to change its name for XQuare (XQuery Advanced Runtime Environment) in order to avoid legal infringement. We hope that the associated disturbances (that may linger for one or more coming releases) will be as slight as possible.

Warning
For that purpose, note that the 1.1.1 maintenance release of products (see below), although its documentation was cleaned with references to XQuark, still use xquark for package names and URI names, ensuring backward compatibility. The complete migration is planned for a subsequent release.

XQuare Fusion 1.1.1 released - September 10, 2005

This is a maintenance release of XQuare Fusion 1.1. It features numerous bug fixes capitalized during the past months. See the details in the release notes.

XQuare Fusion is a powerful information integration engine for querying in real-time multiple, heterogeneous and distributed data sources. Using XML-based data sources federation, it presents to applications a single, uniform XML view of all business information, which can then be queried with XQuery to produce XML documents. Accessible data sources include relational databases (through the XQuare Bridge component), XML documents, Web Services and potentially much more, including XQuery-enabled data sources and applications accessible through JCA connectors.

XQuare Fusion currently supports the following data sources:

  • XML documents
  • XQuare Bridge
  • XQuare Fusion

XQuare Bridge 1.1.1 released - September 10, 2005

This is a maintenance release of XQuare Bridge 1.1. It features numerous bug fixes capitalized during the past months. See the details in the release notes.

XQuare Bridge expands existing relational database functionalities with advanced XML import/export capabilities. It supports flexible extraction and publishing of relational data into any target XML format, using the XQuery language. Using a powerful mapping language, it can also perform efficient insertion of structured XML data into existing relational tables, while taking into account the database integrity constraints and transforming the implicit relations appearing in the XML document into explicit ones in the database. For both storage and extraction functions, XQuare Bridge relies on the XQuare implementation of W3C XML Schema.

XQuare Bridge currently supports the following databases:

  • MySQL 3.23.X and 4.0.x
  • Oracle 8i and 9i
  • MS SQLServer 2000
  • Sybase 11.9.2
