  • 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.
  • Last year we carried out a survey of our content that counted 3 million objects in 80 collections putting us well on track to significantly exceed our content target of 2 million objects published in Europeana. It also revealed varying states of technical readiness among content providers. Year 2 of the project, therefore, has seen content providers focus their efforts on establishing repositories, completing metadata and output formats, configuring harvesting targets, and mapping their metadata to the CARARE XML schema.
  • Metadata, the CARARE aggregation service and 3D ICONS

    1. 1. Metadata, the CARAREAggregation service and 3D ICONS Kate Fernie, MDR Partners, UK
    2. 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 1st February 2010
    3. 3. CARARE objectives• 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
    4. 4. Content The type of content CARARE is making available is:images, text, videos, 3D models and reconstructions…
    5. 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. 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. 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. 8. Content providers repositories (1)• Content and metadata is prepared locally by partners according to institutional requirements
    9. 9. Content providers repositories (2)• Metadata is exported for harvesting or upload – native, CARARE or other standard formats
    10. 10. Metadata mapping and transformation• Metadata in native format is mapped to the CARARE schema in the MINT tool
    11. 11. CARARE metadata schemaA metadataharvesting profiledfor the archaeology Heritage assetand architecturedomain built on: CARARE•CIDOC core data metadatastandards schema•MIDAS heritage Activities Digital resources•LIDO Collection 4 themes
    12. 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 National inventories of monuments 12 and historic buildings
    13. 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 Information sources, 13 representations and reconstructions
    14. 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
    15. 15. The CARARE Metadata schema Collection information Heritage asset *CARARE Digital resource * Activity
    16. 16. Achieving metadata interoperabilityThe Schema acts as an intermediary between the native metadata held by content providers and Europeana EDM Native CARARE metadata metadata schemaMetadata is captured in national language in systems specified to meet local requirements and procurement rules
    17. 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. 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. 19. Transformations• Metadata is transformed to CARARE schema for ingestion to the MORE repository, and• From CARARE to EDM for harvesting by Europeana
    20. 20. Why CARARE to EDM?• Europeana is still working on the implementation of EDM• There have been regular updates and implementation of new elements Activities CARARE EDM
    21. 21. 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. 22. CARARE to EDM (2012) A CARARE object becomes: Several Provided Cultural Heritage Objects with: •Related web resources •ORE aggregations •contextual information about placeSome activity and spatial data can’t currently be mapped
    23. 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. 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
    25. 25. Thanks for your attention!
