The HAPPI Toolkit: from model to implementation
1 like453 views
We can rely on data if and only if its provenance and transformations are properly documented and traced. This presentation shows the implementation of a model for documenting the transformations of digital objects during their whole life cycle. This is a crucial topic in long-term digital preservation archives.
