1. Metadata, the CARARE Aggregation service and 3D ICONS Kate Fernie, MDR Partners, UK

2. 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 1 st February 2010 http://www.carare.eu

3. 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

4. The type of content CARARE is making available is: images, text, videos, 3D models and reconstructions… Content

5. 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!

6. 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

7. 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!

8. Content providers repositories (1) Content and metadata is prepared locally by partners according to institutional requirements

9. Content providers repositories (2) Metadata is exported for harvesting or upload – native, CARARE or other standard formats

10. Metadata mapping and transformation Metadata in native format is mapped to the CARARE schema in the MINT tool

11. CARARE metadata schema Heritage asset Digital resources Activities Collection A metadata harvesting profiled for the archaeology and architecture domain built on: CIDOC core data standards MIDAS heritage LIDO CARARE metadata schema 4 themes

12. Heritage Assets Monuments, historic buildings, landscape areas, shipwrecks, artefacts Record metadata; Title, Description Characteristics - Type, Materials, Dimensions, Inscriptions - Spatial (place, address, map coordinates) - Temporal (date, time span, period) - Craft Actors Designation, Condition References Relations 12 National inventories of monuments and historic buildings

13. Digital Resources Images, texts, videos, audio, 3D models Record metadata; Title, Description Characteristics - Type, format, medium, extent, technical details - Subject, temporal, created Publication statement Actors Link to the object Rights Relations 13 Information sources, representations and reconstructions

14. Activities Field investigations, Surveys, Research and analysis, Historical events, etc. Record metadata Title, Description Actors people or organisations that took part in the activity Characteristics - Type, Method, Materials and techniques used, - Spatial (place, address, map coordinates) - Temporal (date, time span, period) Assessments References Relations 14

16. 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

17. 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

18. MINT tool No fixed submission schema Some providers export metadata directly in CARARE schema or native schemas Easy mapping to the project schema

19. Transformations Metadata is transformed to CARARE schema for ingestion to the MORE repository, and From CARARE to EDM for harvesting by Europeana

20. 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

21. 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 edm:ProvidedCHO ore:Aggregation edm:WebResource for digital representations edm:Agent edm:Place edm:TimeSpan skos:Concept

22. 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

23. 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

24. 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
