and the Europeana Data Model

Ceci n’est pas un monument archéologique

This is a photo of part of a monument

We can see more of the monument from the air

but what’s going on beneath the surface?

lots of different sources of information

help build up the picture of the monument and our understanding

And make this available online

Achieving interoperability with Europeana à  We made a mapping between EDM and the CARARE metadata

schema: finding correspondences between the elements of both models

à  Helps users of the CARARE schema to send good metadata to Europeana

à  Why is it important to report on this?

•  Mapping is rarely an easy issue •  Models are complex, with subtle differences in world views •  Both CARARE and Europeana benefits from “mapping meditation”

•  One of the hardest (confronting) metadata exercises!

•  Sharing concrete experiences benefits all Europeana partners

How does this look in Europeana?

Scenario 1: Monuments are represented as CARARE Heritage Assets and Digital Resources are views of lesser cultural

importance and are treated as EDM WebResources

Scenario 2: Digital Resources are cultural objects qualifying as EDM CHOs

Contextual Resources – Events

CARARE’s event data can be represented in EDM Event class but not yet implemented in Europeana

Conclusions

à  CARARE provides better “profile” for archaeology/architecture

heritage and rich metadata for Europeana

à  In the process of mapping •  We identified non-trivial issues

•  We documented solutions (CARARE->EDM case study)

•  It prompted updates to CARARE’s schema (3D ICONS project) •  It confirms the relevance of a richer model like EDM for Europeana

•  Human supervision remains crucial for choosing the right option •  Data curators can help here as with many other quality issues in data

aggregation projects!
