1 Europeana and schema.org Antoine Isaac Dublin Core Conference Schema.org special session 5 September 2013
2 Europeana Data Model: an example For a general presentation on Europeana and EDM rationale see
3 Provided Cultural Heritage Object (CHO) and descriptive metadata
4 Web Resources digital representations
5 Aggregations Bundling it all together
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 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 Europeana, Creative Commons and RDFa /492A0518CA2BDF09B1642B11FA7317F5FE43B96B.html
9 The Creative Commons Public Domain page triggers a script that harvests mark-up on the Europeana object page
10
11 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

18 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
19 Thank you! Questions? Antoine Isaac
