Metadata, the CARARE Aggregation service and 3D ICONS
Kate Fernie, MDR Partners, UK
CARARE in a nutshell
• A Best Practice Network funded under the ICT PSP 2009 programme.
• 29 partners in 21 countries
• Heritage organisations, archaeological museums, research institutions and specialist digital archives
• Making digital content available to Europeana
• 3 year project which started on 1st February 2010
http://www.carare.eu
•To developing aggregation services to deliver metadata to Europeana
• Customised for organisations with content relating to archaeological monuments and historic sites
• Tools and services to enable the network to make their content metadata interoperable with Europeana
• Promoting standards and good practices
• Removing barriers
CARARE objectives
The type of content CARARE is making available is:
images, text, videos, 3D models and reconstructions…
Content
3D PDF
• CARARE recommended 3D PDF to its content partners as a good standardized platform which is accessible to Europeana’s users
• It has been accepted well by the partners
• Has benefits for users
• Its not the only 3D format
Main focus of this talk is metadata!
The aggregation service
• CARARE defined a metadata schema, • Provides tools:
• MINT – metadata mapping tool • CARARE MORE repository
• Offers a services to prepare metadata to Europeana’s current specification
The CARARE approach
• Original content remains in our content partners repositories and is published on their websites
• CARARE harvests metadata from our partners and uses the CARARE metadata schema as an intermediary to Europeana
Content stays at home!
Content providers repositories (1)
• Content and metadata is prepared locally by partners according to institutional requirements
Content providers repositories (2)
• Metadata is exported for harvesting or upload – native, CARARE or other standard formats
Metadata mapping and transformation
• Metadata in native format is mapped to the CARARE schema in the MINT tool

Achieving metadata interoperability
Native metadata
CARARE schema
EDM metadata
The Schema acts as an intermediary between the native metadata held by content providers and Europeana
Metadata is captured in national language in systems specified to meet local requirements and procurement rules
The CARARE schema provides
• Familiar concepts• Rich where the domain calls for it, e.g.:
• Time – from earliest prehistory to modern dates• Space – place names, coordinates, bounding boxes and polygons
• Monument character• Domain specific documentation in an international language
Supports Semantic and Syntactic interoperability
MINT tool
• No fixed submission schema• Some providers export metadata directly in
CARARE schema or native schemas • Easy mapping to the project schema
Transformations
• Metadata is transformed to CARARE schema for ingestion to the MORE repository, and
• From CARARE to EDM for harvesting by Europeana
Why CARARE to EDM?
Activities
• Europeana is still working on the implementation of EDM• There have been regular updates and implementation of new
elements
EDMCARARE
http://pro.europeana.eu/web/guest/edm-documentation
EDM• The EDM Definition – this is the formal specification of the classes and
properties that could be used in Europeana• The EDM Primer – this is the "story" of EDM and explains how the
classes and properties may be used together to model data and support Europeana functionality
• The EDM object templates: this working document is a simple wiki listing that shows which properties apply to which class and states the data types and obligation of the values. These templates should be regarded as a work in progress

CARARE to EDM (2012)
Several Provided Cultural Heritage Objects with:•Related web resources
•ORE aggregations•contextual information about place
A CARARE object becomes:
Some activity and spatial data can’t currently be mapped
Lessons learned• Having a rich intermediary schema accommodates differences
at home, and protects providers from changes in the target schema
• No matter how good the technologies the quality of metadata is not ensured
• Human supervision is required to achieve good quality at all stages
• Technical support is very important
Next steps• Implement some minor modifications and improvements to the
CARARE schema• Discussions with 3D ICONS to extend the CARARE schema
to include provenance for 3D reconstructions – London charter paradata
• Offer training and support for 3D ICONS partners
