DLF Aquifer seeks material that fits within an American culture and life theme, broadly defined. The Aquifer Collections Working Group will evaluate the collection content to determine whether it is in the Aquifer scope.

The current method for gathering material is by metadata harvesting using OAI-PMH. We ask data providers to make MODS records available according to the Digital Library Federation/Aquifer Implementation Guidelines for Sharable MODS Records. In addition, potential data providers may find the OAI Best Practices useful, in particular the Sharable Metadata and Data Provider Implementation sections.

We understand that many libraries and cultural heritage organizations have metadata in other formats and we are investigating the possibility of providing mapping support for transformations from MARC, EAD and possibly VRA formats to Aquifer style MODS. The Aquifer team is modeling workflows for ingesting new collections and would be glad to work with collection providers and their technical contacts to create flexible methods to add content with metadata in other formats. We strongly recommend that these formats be as rich or richer than MODS or MARC, in keeping with our efforts to provide as much detail as possible. Refer to the MODS Guidelines Levels of Adoption for information on what services can be enabled at each level. It also bears noting that a requirement of OAI-PMH is that data providers also make the oai dc (simple Dublin Core) format available.

As per the Aquifer mission, the metadata we collect should point to digital objects. These digital resources should also be made available for additional purposes within the Aquifer framework, e.g., as thumbnails for asset action services; for manipulation of the resources themselves.

For organizations without OAI data providers or plans to set one up, we are also considering offering a static repository setup service. We welcome the opportunity to discuss this idea with collection providers. For those interested in this avenue, the requirement is XML-enabled metadata.

When collections are submitted, we ask that the provider insure the continued availability of the resources through Aquifer by signing a submission agreement. The agreement also outlines the Digital Library Federation's right to use the digital material and metadata within the Aquifer project.

Digital Library Federation (DLF) is testing a model for transitioning products and services from development to sustainability with DLF Aquifer. The attached prospectus describes Aquifer products and services and outlines a process for organizations to work with DLF to assume responsibility for elements of DLF Aquifer that fit with their strategic goals. Information about levels of resources required to continue the services and possibilities for future development are also included in the prospectus.

DLF will host a question and answer session for interested parties on Thursday, November 13th at DLF Forum. For more information, contact:
