This document discusses mapping the metadata schema for the CARARE project to the Europeana Data Model (EDM). CARARE aggregates cultural heritage content for archaeology and historic buildings and provides it to Europeana. The mapping identifies correspondences between elements in the two models so CARARE can submit good metadata to Europeana. It examines different scenarios for how CARARE heritage assets and digital resources map to EDM classes like ProvidedCulturalHeritageObject and WebResource. The mapping provides better metadata for 2 million CARARE objects in Europeana and prompted updates to schemas. It confirms EDM is relevant for aggregations and shows metadata mapping requires human supervision.
1. Achieving interoperability between the
CARARE schema for monuments and sites
and the Europeana Data Model

4. CARARE: Bringing content for archaeology and
historic buildings to Europeana users
When: 3 year project (2010-2013)
Who: heritage organisations, archaeological museums, research
institutions and specialist archives
29 partners in 21 countries
What: delivering content to Europeana
What: aggregation services and good practices for content
relating to archaeological monuments and historic sites
• Metadata repository (MORE)
• Metadata schema

6. CARARE Metadata Schema
Heritage asset
Digital
resources
Activities
Collection
4 themes
http://www.carare.eu/eng/Resources/CARARE-Documentation
Acts as an intermediary
between the native metadata
of content providers and
Europeana
8. Digital Resources

13. Objectives
Mapping: finding correspondences between the elements of both
models so that CARARE can send good metadata to
Europeana
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 to all Europeana partners
And beyond: cf. goals of DC, “a metadata ecosystem”
15. Mapping CARARE data to EDM
A CARARE object becomes one or several EDM Provided
Cultural Heritage Objects with:
Related web resources
Aggregations
Contextual information about place
Some activity and spatial data cannot currently be mapped
16. Creating EDM resources from CARARE data
edm:ProvidedCHO
HA:PamFond/1978155
ore:Aggregation
http://store.carare.eu/uid/iid:1655549
Heritage Asset’s
identifier
PamFond/1978155
CARARE’s Heritage Assets always give raise to one EDM
ProvidedCHOs with its companion Aggregation
The next issue is whether CARARE’s Digital Resources are also EDM
CHOs…
It depends on the collection!
18. edm:ProvidedCHO 3
edm:ProvidedCHO 1 edm:ProvidedCHO 2
Scenario 2:
Digital Resources are cultural objects qualifying as EDM CHOs
but some are shared among several Heritage Assets
20. Contextual Resources – e.g., Places
CARARE’s geospatial
enrichment represented with
EDM contextual resource
class
21. Conclusions
CARARE provides better metadata to Europeana for 2M objects
In the process
We identified non-trivial issues
We documented solutions (this paper!)
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!

At a working level, we operate in a network of aggregators. We can’t work directly with 2,200 organisations, so we rely on aggregators to collect data, harmonise it, and deliver to Europeana. Aggregators are important because they share a background with the organisations whose content they bring together, so there is close understanding. The aggregation model enables Europeana to collect huge quantities of data from thousands of providers, through only a handful of channels.
This is to give you a very quick overview of the CARARE project and what we have accomplished and are working on. We are a best practice network funded under the ICT Policy Support Programme. We currently have 28 partners in 21 countries as well as several content providers who have joined with us to make their collections accessible in Europeana. Our partners comprise national heritage agencies, museums, research institutions and digital archives, all working to make their images, 3D-models, records and metadata accessible in Europeana.
