Introduction

Digital Dark Ages Project Archipel

  • Disseminate content & provenance

information as LOD

  • Enable long-term preservation

http://www.archipel-project.be/

Problems

  • Persistent URIs (versioning of LOD)
  • Temporality Enrichments
  • Publication of Provenance

Publishing Provenance

Provenance records: datetime conneg

  • first memento (URI-P0)
  • last memento (URI-Pn)
  • memento (URI-Pj)
  • previous memento (URI-Pi)
  • next memento (URI-Pk)
  • timemap (URI-Tp)

+

  • resource of provenance (URI-Mj)

Publishing Provenance

Provenance records: datetime conneg

  • first memento (URI-P0)
  • last memento (URI-Pn)
  • memento (URI-Pj)
  • previous memento (URI-Pi)
  • next memento (URI-Pk)
  • timemap (URI-Tp)

+

  • resource of provenance (URI-Mj)

To allow switching between resource and provenance of that resource.

Conclusions

  • Disseminate content & provenance information as LOD
  • Enable long-term preservation
  • Persistent URIs (versioning of LOD)
  • Retain Temporality Enrichments

Conclusions

  • 5-star deployment scheme:

– 6 stars for supporting datetime conneg

Preserve temporality when enriching

– 7 stars for publishing provenance

Allow quality checkers, License checkers,

  • etc. ( use cases Provenance XG)

Future Work

  • Standardisation PREMIS OWL
  • Extend MementoFox plugin to catch provenance HTTP

link

  • PREMIS OWL suited for publishing provenance on the

Web?

  • Focus on the use of Provenance
