The document discusses the integration of the Europeana data model with schema.org to enhance the visibility and accessibility of cultural heritage data through improved search engine optimization and data exchange. It highlights various mappings of Europeana's descriptive metadata to schema.org properties, showcasing the efforts to standardize data representation for better user engagement. Additionally, it addresses the practical implications of this mapping, acknowledging limitations while emphasizing the benefits of reaching a broader audience.

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 http://pro.europeana.eu/edm-documentation

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

9. The Creative Commons Public Domain page triggers a script that harvests mark-up on the Europeana object page

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!
