California Digital Library Announces Release of XTF Version 3.1


Oakland, CA, August 6, 2012 - The California Digital Library (CDL) is pleased to announce the release of version 3.1 of XTF (, an open source, highly flexible software application that supports the search, browse and display of heterogeneous digital content.  XTF provides efficient and practical methods for creating customized end-user interfaces for distinct digital content collections and is used by institutions worldwide. 

Major features in the 3.1 release include:

·         Improved schema handling for EAD finding aids.  In addition to EAD 2002 DTD,  XTF now provides support for search and display of:

o    EAD 2002 schema and EAD 2002 RelaxNG finding aids

o    Output from Archivists’ Toolkit and Archon

See the 3.1 change log ( for further details.

The XTF website also provides a self-guided tutorial and a sample of the default installation (, demonstrating the capabilities of the tool out-of-the-box. Both of these resources provide a quick view of the capabilities of XTF prior to download.

Offering a suite of customizable features that support diverse intellectual access to content, XTF interfaces can be designed to support the distinct tools and presentations that are useful and meaningful to specific audiences.  In addition, XTF offers the following core features:
