eXtensible Text Framework (XTF)
Commissioned by the California Digital Library (CDL) to be the primary access tool for its collections, the eXtensible Text Framework (XTF) provides a powerful, flexible platform for providing access to digital content. It consists of Java and XSLT 2.0 code that indexes, queries, and displays digital objects. The software is actively maintained and supported by CDL developers and is in use at institutions across the U.S.
The XTF source code is based on open source software (e.g., Lucene, Saxon) and is itself freely available for developers to download, install and configure their own instance of the software. Developers from government agencies, university presses, and other cultural heritage institutions such as RLG are currently experimenting with XTF. Learn more.
