The CDL eXtensible Text Framework (XTF) is a flexible indexing and query tool that supports searching across collections of heterogeneous data and presents results in a highly configurable manner. The highlights of the XTF system are described in an online brochure

The MetaScholar Initiative of the Robert W. Woodruff Library at Emory University encompasses more than ten digital libary projects undertaken in the past six years, and has received funding from sources that include the Andrew W. Mellon Foundation, the Institute for Museum and Library Services (IMLS), the National Science Foundation (NSF), and the Library of Congress.

The MetaScholar Initiative is currently working on seven main projects: MetaArchive, AmericanSouth, MetaCombine, Music of Social Change, OCKHAM, a Study of User Quality Metrics, and the open access journal Southern Spaces. This Initiative is creating new models for sharing and organizing meta-information, tools for the preservation of at-risk digital objects, and services for scholars in focused research areas. It is also creating new tools for such sharing, including the Metadata Migrator application and the OCKHAM digital library services.

The Metadata Migrator software package, funded by the Institute of Museum and Library Services, allows institutions such as museums, archives, research centers, and small libraries to make their locally stored records available for online searching using the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH).
