MANAGE What provisions are needed for long-term management? PROVIDE What considerations are there for long-term access? The digital preservation lifecycle

3 But first, a story…

4 digital objects metadata how an object is ingested into storage the best storage option for your object At the end of this module you will have an understanding of:

5 Files + metadata = digital object

7 Metadata is structured information associated with an object for purposes of: discovery description use management preservation

8 Well-managed collections Characteristics of well-managed collections include: basic information about each deposit metadata for the object common (or normalised) file formats controlled and known storage of content more than one copy in more than one location

9 Metadata characteristics ContentFixityReferenceProvenanceContext Pre-ingest

10 Preservation metadata Content (what), Fixity (unchanged), Provenance (life story), Reference (this thing), Context (relationships) Administrative (manage) Structural (understand, use) Descriptive (find, use) Diagram courtesy DPM Workshops

11 Digital preservation metadata checklist Content: the file Reference: unique identifiers Provenance: trace to origin (or to deposit) Context: preserve linkages with other objects Fixity: demonstrate content is unchanged, e.g. checksum
