Fundamental Assumption #1No single system can provide the full range of repository-based solutions for a given institution’s needs,

…yet sustainable solutions require a common repository infrastructure.

No single institution can resource the development of a full range of solutions on its own,

…yet each needs the flexibility to tailor solutions to local demands and workflows.

Fedora is the digital repository system,holding the content in a structured way

Hydra and digital preservation

• Hydra Digital Preservation Interest Group

• Linking Hydra to digital preservation tools/services– Archivematica– Archivesphere

• Embedding preservation metadata within Hydra– Expanding PCDM– Making sense of Premis

• Hydra as component of digital preservation infrastructure– Royal Library of Denmark– LSE

Archivesphere

• A project from Penn State University to extend their Scholarsphere/Sufia Hydra head to include preservation actions– Format migration– Embedded FITS

• Dilemma of what to include and what not to include– Don’t want to re-invent the wheel

• Hydra DP Interest Group project on preservation actions– Identifying what may best sit within Hydra and

what best sits elsewhereInfusing Hydra with digital preservation capabilities | 11 March 2016 | 9

Using PCDM to capture digital preservation

• PCDM – Portland Common Data Model– Common way to structure digital objects in a

repository– How can this be expanded to include digital

preservation information?– Hydra DP Interest Group project to identify how

to extend PCDM for digital preservation

Making sense of Premis

• How can Hydra make effective use of Premis data dictionary?

• Hydra DP Interest Group project exploring options– Building on experience to date from across the

Hydra community– Focus on practical mechanisms, not assessing

which parts of Premis should or should not be used• Initial interest in Premis events

• Interest in Premis OWL ontology given Fedora 4 use of RDF

In summary

• Hydra has the flexibility to embed digital preservation capabilities in a number of ways

• Community is in the process of finding its way with identifying best practice– Building on lots of local experience and initial

implementations– Extending community initiatives, not re-inventing

the wheel• Building on and enabling Fedora’s underlying

support of durability
