    1. 1. Europeana and schema.org Antoine Isaac Dublin Core Conference Schema.org special session 5 September 2013
    2. 2. Europeana Data Model: an example For a general presentation on Europeana and EDM rationale see http://pro.europeana.eu/edm-documentation
    3. 3. Provided Cultural Heritage Object (CHO) and descriptive metadata
    4. 4. Web Resources – digital representations
    5. 5. Aggregations – Bundling it all together
    6. 6. Why using schema.org? Europeana tries to disseminate data to reach out to as many users as possible Search engines • Customization of result lists – rich snippets • Knowledge Graph • Search Engine Optimization Developers more comfortable with parsing web pages
    7. 7. In fact: schema.org and RDFa Europeana has been publishing structured metadata via its portal since a while One application case: customization of public domain pages by Creative Commons, with details on the work and Europeana usage guidelines for public domain works
    8. 8. Europeana, Creative Commons and RDFa http://www.europeana.eu/portal/record/02001/492A0518CA2BDF09B1642B 11FA7317F5FE43B96B.html
    9. 9. The Creative Commons Public Domain page triggers a script that harvests mark-up on the Europeana object page
    10. 10. Going further Creative Commons uses 5-6 fields, Agreed upon with the developer(s) there What to publish further? Schema.org as a standardized form of more web page-based data exchange And it has a case – several ones in fact Still quite prototype-ish

    17. 17. Observations • Schema.org is simple • Not everything can be mapped • We’re losing grain, including some of the core benefits of Europeana moving to the richer EDM! • But it’s ok, because it matches needs • And in fact it’s not entirely because of Schema.org • And we can publish different flavors of the data in RDFa
