The Keystone Digital Library Suite is a family of Open Source digital content management, portal management and information discovery software packaged together to provide libraries, museums and archives with state-of-the-art digital library services.
The Keystone Digital Library Suite has two Major Components: Keystone Organizer and Keystone Retriever.
Keystone Organizer is both a content management service and a portal management service that stores all forms of digital content and facilitates metadata creation to describe that content. It also serves as the knowledge base for the federated search services, the harvesting services and the link resolver services that are elements of Keystone Retriever, as well as for its own portal management services. This means that library staff have one type of interface and one look-and-feel for all administration services and metadata creation throughout Keystone DLS.
Keystone Retriever is a family of information discovery services that includes federated searching, harvesting services, and link resolution for linking from citations to full text. Index Data is also offering its Keystone Resolver either as a stand alone product or as part of its family of Keystone Retriever services. At this time Keystone Retriever uses third party electronic serials management systems to provide Keystone Retriever with the data it needs to perform its linking.
