Definições

PremIS (Preservation metadata: Implementation Strategies) is one attempt at specifying the semantic units needed to support core preservation functions. Core preservation metadata is relevant to a wide range of digital preservation systems and contexts, and it is what “most working preservation repositories are likely to need to know” to preserve digital material over the long term. This includes administrative metadata, but also generic technical metadata that is shared by all content types. It permits the specification of structural relationships if this is relevant for preservation functions, but users may chose to instead use the structural relationships offered by their container metadata specifications. (Bib:2010#Dappert e Anders)
