Pentaho Metadata

Pentaho Metadata defines a business model and query implementation that makes it easy for business users to query data sources in tools such as Pentaho Report Designer and Pentaho Ad Hoc Reporting. This page is geared towards developers interested in using Pentaho Metadata in their projects, or adding capabilities to Pentaho Metadata.

Pentaho Metadata consists of three sub-projects, pentaho-metadata, pentaho-mql-editor, and pentaho-metadata-editor. pentaho-metadata is the home of the core metadata engine, while the mql editor code provides a SWT tool for building an MQL query, and the editor, which allows the building of metadata models. The Report Designer and BI Platform also contain client side metadata code that demonstrate using metadata in apps.
