This presentation was delivered by Noa Campos López and Marcel Hellkamp from PERICLES project partner Georg-August-Universität Göttingen (GWDG), at the interactive workshop ‘Eye of the Storm: Preserving Digital Content in an Ever-Changing World’ (Wellcome Collection Conference Centre, London, 2 December 2016).
This full-day event aimed at introducing and experimenting with the PERICLES model-driven approach demonstrating its usefulness for managing change in evolving digital ecosystems.

11. Example: Ingest Digital Artwork
●Policy: ”Digital artwork needs to be analysed
and packaged before storing”
● Preservation action: ingest digital artwork
1. Check executables for viruses
2. Extract metadata (e.g. assets, runtime
dependencies, 32/64 bit, OS)
3. Package executable, assets and metadata in a
specific format (e.g. BagIt)
16. Example: Ingest Digital Artwork
v2.0
● Preservation action: ingest digital artwork
1. Check executables for viruses
2. Extract assets metadata
3. Extract requirements (runtime dependencies,
32/64 bit, OS)
4. Add artist’s personal information to
metadata.
5. Package executable, assets and metadata in a
specific format (e.g. bagit)
