  6. Europeana principles • Common access to digital cultural heritage objects across different domains • Complementing and not duplicating the access type provided in the different domains through specialised portals, locally-based • Neutral view of the digital objects compared to any of the traditional domains view • Digital objects at the lowest possible level of granularity • As direct as possible access to the digitised object • Minimum click distance between a description and the object • Search and discovery of objects • Common central index of the objects’ metadata • Object centric approach and not collection centric approach

  7. Europeana content • Europeana stores representations of digital objects and not the digital objects themselves • On Europeana side: • Description and preview by means of metadata • On institution/aggregator side: • Repositories where digital objects are stored • Original website to view, play and reuse the objects

  8. Europeana data model • Needs to interoperate with the data models used by contributing projects and aggregators when ingesting the contributed data • Needs to handle data created by Europeana at the ingestion stage & user generated content • Needs to support the Europeana content dissemination • to the user centered services proposed in the Europeana business model • to other applications building services based on the Europeana repository of Digital Objects metadata

  9. Europeana ingested data • Europeana data includes: • Metadata (descriptive, administrative) describing a digital object • Preview (thumbnail) of the described object • Active links to the described digital object on the provider’s site • Same level of granularity between Europeana data and the digital object • To ensure for the user consistency and predictability for search and navigation across the domains and collections • Aggregators are here key players in preparing the data!

  10. Digital object in Europeana • Definition • A unique single entity which can be viewed/played by users – e.g. mpeg movie, mp3 audio, jpeg photo, PDF text etc... that users view on their computer. • Digitised version of a physical/analogue cultural item/artifact • Ex of non-digital objects: museum description – even extensive, scanned catalogue card

  11. Digital object in Europeana • Granularity • User-centric approach: Is useful/relevant to the user, level-specific value. Ex page level: Botanical plate with specific description • Can be at different levels: E.g. book/page, newspaper title/issue, music record/song, film/movie/audio/script/poster/..., etc... • Lowest possible level with • Direct access – one-click from Europeana to the object • Level-specific description

  12. Is it interesting to provide direct access to this herbarium plate? • Probably yes, BUT: • No extracted species names… • No description of the plate… • No direct link to this image of the plate (address bar URL) points to the 1st image of this digitised book…

  13. Session content • Europeana.eu • Service • Principles • How to contribute content? • Technical requirements in a nutshell • Data ingestion workflow • Resources: docs, tools, team… • Technical evolution and developments • Roadmap: Rhine & Danube • EuropeanaLabs.eu • Europeana and the projects • Group of current and coming projects • Collaboration requirements

  14. Technical requirements in a nutshell • Digitised object available on a website at the object level through a permanent direct link • To the object and/or the object in context • To a thumbnail or a sample • Metadata at the digitised object level following the metadata elements set defined by Europeana for the general interface • Qualified Dublin Core (at the moment only simple DublinCore Indexed and displayed) • Preferably exposed in XML for harvesting on an OAI-PMH server

  16. Aggregators Handbook • Provide overall information and tools to aggregators in order for them to provide metadata to Europeana and related institutions. • Organised in 6 areas: • Organisation • Business • Technical & Operational • Dissemination • Aggregator Case Study • Services & Contact

  17. Workflow:Data submission procedure of the Europeana Office

  18. Submission procedure • [Provider/Europeana] Partnership/contractual agreement • [Provider] Analysis and description of submission • Data sets, volumes, schedule, availability of links, thumbnails, rights information • [Europeana] Assessment of submission • Content strategy (type, geographical provenance, principles), technical strategy (harvesting policy) • [Provider/Europeana] Negotiation/agreement • [Provider] Data preparation, repository setup and population, testing • [Europeana] Formal ingestion

  19. Tools & doc [2/2]Technical resources • Data requirements: • Europeana Semantic Elements Specifications v3.2.2 • ESE XML Schema • Data preparation aids: • Mapping and Normalisation Guidelines for Europeana • Specifications for Europeana thumbnails • Definition of Digital Object in Europeana context • Validation tool • Content Checker [demo]

  20. The Content Checker • = Validation tool available to providers before submission to production environment. 2 parts: • The Content Checker Ingestor • Allows uploading of a data set • Validation against the ESE V3.2 XML schema • Importing the data into the database • Indexing of data • Caching of thumbnails • The Content Checker Portal • Separate from the operational portal • Allows provider to search for and view uploaded data • Ensure the appropriateness of the mapping decisions

  21. Select “New Data Set” to create a new Data Set widget. The Ingestor automatically assigns an identifier to the Data Set, 999901 in this example

  22. Enter a description and press “Save”

  23. Description is saved. A data file with records can now be selected from the file system and uploaded

  24. The file upload is followed by a validation step of the data against the ESE XML Schema

  25. If it is ok the validation step is followed by the actual import of the records

  26. Indexing can now be started for the imported records

  27. Press “Start caching” to initiate caching the thumbnail images of the Data Set’s records. This step requires also a confirmation. The indexing job is started

  28. The Data Sets records are indexed and available for search in the Content Checker portal. The caching job is started

  29. Caching is finished

  30. http://contentchecker.isti.cnr.it:8080/portal/brief-doc.html?start=1&view=table&query=europeana_collectionName%3A999901http://contentchecker.isti.cnr.it:8080/portal/brief-doc.html?start=1&view=table&query=europeana_collectionName%3A999901 Search for europeana_collectionName:999901 gives results corresponding to all the records indexed for the Data Set 999901. The thumbnail images are visible europeana_collectionName:999901

  37. What does Europeana.eu need from the projects? • Content compliant to ESE • Content tested in test sites provided by Europeana, normalised, quality checked and ready for ingestion. • Software Development that has full functional testing • A Distributed Development Community

  38. What should projects plans include? • People able providing support/expertise in interoperability: • Able to understand technical Europeana requirements, expressing the projects’ need, • Tasks that will enable/facilitate contribution to Europeana: • Analysis of technical requirements • Setting up of necessary infrastructure: metadata transformation, repository, dissemination (OAI-PMH) • Testing: quality control • Survey of content in terms of provenance, volumes, delivery dates for initial submissions and updates
