The viewpoint from the European Council of Ministers in 2008. The Digital Agenda for Europe, the PSI-directive and the Commite des Sages expert group have clearly pointed to the strategic value of Open Data and a preserved Public Domain.

Present and planned technical interfaces for data re-use. Today I will focus on our Search API Europeana Search API, to feature all present and future portal functionalities Europeana API programming libraries and CMS-modules, e.g.: Java programming library Popcorn.js plug-in for open and contextualised video CMS modules/components for VuFind, Joomla&Wordpress exists Europeana Linked Open Data pilot, to develop to contain all content Europeana collection data dumps, a secondary outcome of our LOD-pilot Europeana OAI-PMH server, in development Europeana sitemap/browse all for SEO, to be improved for quicker crawling and richer semantic mark-up Europeana widgets Search widget, to be improved and become openly available Embed item, to be improved and comply with the industry standard oEmbed API User created galleries, in planning
What we haveSome examples that may serve as an inspiration on how the Europeana Search API could be used by the Finnish Digital Library and your partner organisations.
Presentator
Presentatienotities
What we have Some examples of API-implementations that are especially relevant to the Finnish National Digital Library and to GLAMs with on-line collections in general Currently about 15 Europeana partners have made Europeana Search API implementations They constitute an increasing amount of “quality traffic” to Europeana and by extension to our partners Quality: High engagment metrics like depth of navigation, click-throughs, time on site, etc. All non-comemrcial Europeana network partners are currently eligible to use the API We hope, ultimately, that the Europeana API (or widgets) will be in use by ALL our partners with end-user services Or if our API doesn’t fancy you – we plan to offer full collection harvests via OAI-PMH to use locally
Kringla, the Swedish national museum portal
www.kringla.nu
Presentator
Presentatienotities
Kringla is a portal built on the SOCH aggregator API It encompasses the collections of about 15 Swedish institutions, mostly museums Europeana harvests SOCH via OAI-PMH Kringla allows users to cross-search SOCH and Europeana both, in this example a search for items related to Finnish architect Alvar Aalto Via the Europeana Search API SOCH results are filtered out from the Europeana API responses to avoid duplicate records A similar function in the Finnish Digital Library should be simple to develope Guesstimate, one week of development, mostly spent on UX
The CERL Thesaurus
cerl.thesaurus.org
Presentator
Presentatienotities
The Consortium of European Research Libraries thesaurus of persons, publishers and places It encompasses the major European scientific authors of the print era Europeana will harvest CERL content via The European Library OAI-PMH Whenever a user views an author in the CERL Thesaurus they see a sidebar list of digitized works of or about that author in Europeana Via the Europeana Search API using the CERL authority names and synonyms as search parameters for full recall and increased precision Here an example showing the result for the Finnish author and poet, Johan Ludvig Runeberg A similar function in the Finnish Digital Library should be simple to develop Guesstimate, one week of development, mostly spent on UX
The Polish Federated Digital Libraries

Presentatienotities
The Polish Digital Federated Digital Libraries, http://fbc.pionier.net.pl/owoc/main They’ve developed a cross-search functionality for their main search site And a related content from Europeana widget for the member library sites That uses the Google Translate API for multi-lingual queries, the polish keywords are translated into the major European languages before being fed into the Europeana API as query parameters Both implementations use the Europeana Search API Their content is harvested via OAI-PMH to Europeana so their own content is filtered out of the search results they fetch from the API
What we could haveSome of the prototypes and potential API- clients we’ve had to say no to.

Hack4Europe and the EU Digital Agenda Some prototypes that will have to remain as prototypes Also others: Wikipedia batch uploading Europeana content in Artfinder Europeana content in Layar
Artfinder, a site to engage with art and other art afficionados

Presentatienotities
Artfinder, allows users to engage with art and artists www.artfinder.com Social sharing, tagging and commenting User created galleries, also shareable Themed content apps for iPad Shortcuts to GLAM-partners for buying reproductions or downloading high-res version The business model, income from the apps and ordered reproductions is shared between GLAM-partner and Artfinder You pay for the service, not the content!!! This is one of the major business models of Open Data and Content.
INA.fr – the French national audio-visual archives
Presentator
Presentatienotities
INA.fr, the French national audio-visual archives www.ina.fr A major Europeana content provider of audio-visual content But their portal is partially financed by ads – so we can’t share Europeana metadata in return! This is true also for BBC who have ads for international users on many of their services
Wikipedia & Wikimedia Commons - the world’s largest online encyclopedia
Presentator
Presentatienotities
The Wikimedia projects, including Wikipedia and the media library Wikimedia Commons is one of the Top 10 destination sites globally and a natural starting point for most people looking for information on the web A huge multi-lingual platform for distribution and engagement with GLAM content The above is screenshot is from an ongoing limited pilot to test uploading of content to Wikimedia Commons via the Europeana API It can’t move from pilot to production without an adoption of DEA as all Wikimedia project content and metadata must be Open
Hack4Europe winner of the Commercial Potential Award: Art4Europe
Presentator
Presentatienotities
Commercial potential: Art4Europe Android application identifying artworks Uses image recognition Or QR-codes Uses Google Translate to translate descriptions of the artworks Can also read the descriptions through speech synthesis Can be built and deployed per museum/institution Can then be marketed as a free app or for a fee Or freemium Can also include links between artworks and the museum shop to by replicas, posters or other on demand services
Hack4Europe winner of the Inclusion Award: Casual Curator
Presentator
Presentatienotities
Inclusion: Casual Curator Android application for curating and sharing personal collections of Europeana content Mashup with Freebase User selects up to twenty images forming a gallery Giving it a name User publishes/shares gallery on social networks
Hack4Europe winner of the Innovation Award: TimeMash
Presentator
Presentatienotities
Innovation: Time Mash An Android application Search and Geo-location aware search of Europeana Google maps Allows users to take photos and connect with Europeana objects Allowing for Then – Now photo comparisons User photos uploaded to Blogspot or Flickr Includes geotags through the users current GPS position
Without an Open Data license we can’t move beyond prototype with any of the examples listed!Culture: Open Data will allow more people to access and engage with cultural contentCreativity: Open Data, allowing re-mix and re-use, will fuel creativity and engagementGrowth: Open Data, allowing anyone to develop services, will lead to economic growth and increased demand for what GLAMs can offer

Europeana as a platform and network of dataEuropeana and our GLAM-partners cannot reach our goals by being destination sites only. To reach out to and engage with users we need become a network of data, a European Information Space.

National Repositories and Portals – these pose no issue from an API Terms of Use perspective. A number of national portals and other GLAM-sites use the Europeana API in their end-user services. 2. International Repositories and Portals – Europeana has a memorandum of understanding to share content with the Digital Public Library of America. There are other similar initiatives in other non-European countries that theoretically could cooperate with us in a similar fashion, e.g. the Australian Digital Library Trove. 3. Thematic Repositories and Portals - these pose no issue from an API Terms of Use perspective. One such thematic repo and portal is the audio-archive platform DISMARC. 4. The Wikimedia projects, Wikipedia, Wikimedia Commons. Due to their strict Open Content policies Europeana cannot share metadata with them and thus help to improve the trustworthiness of Wikipedia by offering trusted GLAM-content. Wikipedia is one of the Top 10 visited platforms and together with Google it forms the natural starting point for most people when looking for information. Including the kind of information GLAMs hold. Europeana is running a pilot project with Wikimedia Commons upload and is looking for a partnership with the Wikipedia community. 5. General purpose search engine. Europeana content is indexed by Google and other search engines. Traffic from Google consitutes c. 60% of all Europeana visits. The crawling is being done despite Europeana currently being open only for non-commercial use. 6. A number of commercial companies offering sites and apps with cultural content have applied for access to Europeana. Among them are Artfinder.com, Layar and a number of mobile app developers. With both Android Market and AppleStore being clearly commercial and the only real distributors of apps can we even allow free apps? The answer we’ve had to give them is No. 7. Social platforms and networks. Europeana encourages individual users to share content on these platforms and we also use them ourselves to engage with our users and market our/your content. Like search engine indexing this may be a formal break with the current exchange agreement. 8. Personal blogging platforms. Europeana features some widgets that allows users to embed objects on their personal sites. As these sites are commercial platforms and sometimes features adds this may be a formal break with the current exchange agreement..

With the DEA we can allow all these distribution flows of traffic and users, these avenues of engagement to scale without increasing negotiation costs or administrative overhead. Europeana could potentially grow “dark” and act as an information hub (primarily or only) rather than a destination portal. We firmly believe this is the best way to reach out to, increase and engage with our audience!
