Preservation

The basic steps in preservation to counter changes are:

  • create adequate Representation Information for the Designated Community and/or
  • transform to another format if necessary or
  • if preservation cannot be carried on by the current organisation then hand over to the next organisation in the chain of preservation

The mantra is therefore “collect Representation Information, transform or hand on to the next in the chain of preservation” rather than “emulate or migrate”.

Evidence about the authenticity of the digital objects must also be maintained, especially when the objects are transformed or handed over (see below).

Confirmation of the quality of preservation can come from an Audit (with possible certification)

Deliverable D25.1 Interoperability objectives and approaches (2946). In D25.1 some possible solutions to fill these gaps (below) have been proposed. An example in the domain of preservation metadata is represented by the broad adoption of international standards and abandoning local solutions and ad-hoc metadata schema. The most promising standard we have identified is PREMIS Data Dictionary for Preservation Metadata.

Several sources of evidence of the effectiveness of the implementation of the PREMIS data dictionary have been presented at the iPRES2013 workshop titled “PREMIS Implementation Fair 2013”.

Apart from the aforementioned paper, a tool based on this approach (called RIMQA) has been implemented and experiments are reported in that paper.

Gaps

Interoperability. Several interoperability gaps have been identified and classified in D25.1. In particular the following domains have been investigated: 1) Identification systems (for digital objects, authors and datasets) 2) Library classification systems 3) Library Linked Data 4) Metadata 5) Ontologies and Vocabularies 6) Data Provenance 7) Preservation tools 8) Exchange standards 9) Preservation Frameworks 10) Semantic annotation services 11) e-Science infrastructures.Some of the identified gaps can have strong impact on preservation strategies and activities. Some examples follow.

  1. Lack of cross-organization coordination in the definition of metadata preservation schema to capture, maintain and share information about provenance, authenticity, preservation activity, technical environment, rights management and so on. This has led to the development of a set of metadata reflecting the particular needs and requirements of the specific community that authored them.
  2. Lack of a scalable infrastructure for the efficient planning and application of preservation strategies for large and heterogeneous data collections.
  3. Many different suites and preservation tools are in use in different communities (e.g. iRODS, LOCKSS). The isolation from each other represents an obstacle for inter-institutional preservation and interoperability.
Although critical for e-science, the community is not aware about the loss of specificity that happens when world models (ontologies, taxonomies, thesauri, controlled vocabularies) evolve over time.
