Europeana Data Model: a Collaborative Effort
Cross-community development
Involving library, archive and museum experts
Ca. 60 participants
http://pro.europeana.eu/edm-documentation
EDM: an example
Provided Cultural Heritage Object (CHO) and descriptive metadata
Web Resources – digital representations
Contextual Resources – Places
EDM is based on existing ontologies
OAI-ORE (Open Archives Initiative Object Reuse & Exchange): organizing an object’s metadata and digital representation(s)
Dublin Core : descriptive metadata
SKOS (Simple Knowledge Organization System) : conceptual vocabulary representation
CIDOC-CRM : event and relationships between objects
Allowing different semantic grains
The theory: Providers provide data close to original models
Using mappings to more interoperable level
statement at generic level
statement at specific level
Different semantic grains
EDM uses specialization of classes and properties.
It will enable the definition of extensions, “applications profiles” answering to the need of specific communities.
A Collaborative Effort (2)
EDM makes Europeana ready to ingest metadata that is closer to specific community concerns
But still mapped to common elements
Europeana & partners can develop EDM “profiles” upon which everyone could build specific functionality
Based on best practices from sector or domain level

DM2E Data Model
• Semantically and structurally heterogeneous data– Complex hierarchies (EAD, METS)– Object data and transcriptions (TEI)– MARCXML, MAB2, etc.
• DM2E’s Data Model specializes EDM for the domain of handwritten manuscripts
Specialization of EDM in DM2E - Example
Reuse of Existing Ontologies in DM2E
• Types, roles and relations between agents– Friend-of-a-Friend (FOAF) : types of agents)– Publishing Roles Ontology (PRO) : roles of agents in the
publication process– VIVO : types of agents
• Detailed semantics on bibliographic entities– FRBR-aligned Bibliographic Ontology (FaBiO)– Citation Typing Ontology (CiTO)– Bibliographic Ontology (BIBO)
Guidelines for Specialising EDM
• Empirical analysis of source metadata
• Iterative mappings to the EDM
• Close cooperation with data providers for feedback and revisions
• Create new classes or properties only if there is no other suitable option available from existing ontologies
