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
