4. The road travelled

The basics: search, record
• More advanced stuff:
spatial search, time interval search,fielded search,
who/what/when/where search, similar records
• We added support for My Europeana
– Authentication, Saving&tagging records, Retrieving
saved/tagged records.
• We've added some new record response formats:
JSON-LD, RDF/XML
• “Can I use it?”-filter added
• Timestamp queries (time of update/publication in
Europeana)
• We have “official” client libraries for Java and Ruby.
And community created ones for PHP, Django, Python
(1,2) and Node.js

5. Looking forward

6. Query translation
• Will allow translation of search keywords into other
languages
– Intended to be used to then expand the follow up
query
– Church OR Kerk OR Kirche OR Kyrka...
• Based on querying Wikipedia interwiki links
– And will thus work best for named entities: places,
persons, periods, subjects, topic, famous works, etc.
• ETA: August
– If it passes the load tests. Those OR queries can be
scary.

7. Media queries
• Will allow filtering results to only objects that have links
to media files
– Give me all object matching “what: Charles Dickens”,
where media type=IMAGE and which has links to
images
• Will allow filtering of results based on technical qualities
of the linked media files
– “Give me all objects matching “what: Charles
Dickens”, where media type=IMAGE and which have
links to images that are 1MP+
• Will focus on images first but will also support querying
on technical qualities of audio files, text files, and video
files
• ETA: Turn of the year

8. Annotations
• Will allow authenticated My Europeana users to add
public annotations to records in Europeana and which
will be indexed/stored for search and display
• Tags, Image annotations, Sets
– Other types of annotations to be added after these
first three. Ideas on which would be the most useful
welcome!
• ETA: Turn of the year

9. Other protocols and APIs
• OAI-PMH server
– For when you want a full local copy
– ETA: August
• Topped up triple store and SPARQL end-point
– For really complex queries with results in RDF
– ETA: August
• Semantic enrichment API
– For aligning strings with things
– ETA: Turn of the year

10. Ideas
• SSL encryption
• Custom facets
• API-health report
• Others?
