Behind every digital object, there is usually metadata with descriptive information about the object. But metadata for access and discovery is no longer enough. Now, digital library professionals are looking to the future with an eye towards preservation, not only needing to preserve the digital objects themselves but also the valuable metadata that goes along with it.
Enter PREMIS (Preservation Metadata: Implementation Strategies):
According to the publication Understanding PREMIS, preservation metadata "supports activities intended to ensure the long-term usability of a digital resource."
The motivation for PREMIS is based on the needs for implementing a digital preservation repository, which requires keeping important information about its digital objects to enable long-term management. As stated in Understanding PREMIS, "the primary uses of PREMIS are for repository design, repository evaluation and exchange of archived information packages among preservation repositories."
Note: I believe that the use and development of this preservation metadata standard should be a regular part of the digital library process.
