Metadata can play a vital role in enabling the effective management, discovery, and re-usability of digital information. Digital preservation metadata provides provenance information, supports and documents preservation activity, identifies technical features, and aids in verifying the authenticity of a digital object. This presentation gives and introduction to Digital preservation matadata and preservation metada in practise. Presentation was delivered during the joint DPE/Planets/CAPAR/nestor training event, ‘The Preservation challenge: basic concepts and practical applications’ (Barcelona, March 2009)

Elements Defined in Both METS and PREMIS PREMIS METS PREMIS <relationship>: all kinds of relationships, including structural METS structMap: structural relationships, hierarchical, links the elements of the structure to content files and metadata PREMIS identifiers: explicit linking between entity types METS ID/Idref: used to associate metadata in different sections and for different files PREMIS: <format> METS: MIMETYPE PREMIS: fixity METS: CHECKSUM, CHECKSUMTYPE PREMIS: size METS: SIZE
