OCLC has announced the availability of a Digital Archive service.
Here's an excerpt from the press release:
The service provides a secure storage environment for libraries to easily manage and monitor master files and digital originals. The importance of preserving master files grows as a library's digital collections grow. Libraries need a workflow for capturing and managing master files that finds a balance between the acquisition of both digitized and born-digital content while not outpacing a library's capability to manage these large files. . . .
The Digital Archive service is a specially designed system in a controlled operating environment dedicated to the ongoing managed storage of digital content. OCLC has developed specific systems processes and procedures for the service tuned to the management of data for the long term.
From the time content arrives, the Digital Archive systems begin inspecting it to ensure continuity. OCLC systems perform quality checks and record the results in a "health record" for each file. Automated systems revisit these quality checks periodically so libraries receive up-to-date reports on the health of the collection. OCLC provides monthly updated information for all collections on the personal archive report portal.
For users of CONTENTdm, OCLC's digital collection management software for libraries and other cultural heritage institutions, the Digital Archive service is an optional capability integrated with various workflows for building collections. Master files are secured for ingest to the Digital Archive service using the CONTENTdm Acquisition Station, the Connexion digital import capability and the Web Harvesting service.
For users of other content management systems, the Digital Archive service provides a low-overhead mechanism for safely storing master files.
