“There is a tsunami of data that is crashing onto the beaches of the civilized world. This is a tidal wave of unrelated, growing data formed in bits
and bytes, coming in an unorganized, uncontrolled, incoherent cacophony of foam….
we see graphic designers and government officials, all getting their shoes wet and slowly
submerging in the dense trough of stuff…. they walk stupidly into the water, smiling—a false
smile of confidence and control. The tsunami is a wall of data—data produced at a greater and greater speed … in amounts that double, it
seems, with each sunset ....

... [Thankfully] Google mastered the technical art of the
search.”

But Europeana’s aims are different
Trusted data from European cultural
heritage

Before that - a quick aside
![Page 10: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/10.jpg)

End of aside
![Page 17: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/17.jpg)
The obvious way of exposing data:
Europeana Portal
![Page 18: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/18.jpg)
More contemporary dissemination:
Europeana API
![Page 19: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/19.jpg)
More contemporary dissemination:
Europeana Linked Open Data
![Page 20: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/20.jpg)
More contemporary dissemination:
Europeana SPARQL Endpoint
(experimental / temporary URL in 2013)
![Page 21: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/21.jpg)
Linked Data & aggregation of data for others - source
and quality of data is paramount
![Page 22: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/22.jpg)
Europeana and TEL are testing the
waters of resource discovery
![Page 23: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/23.jpg)
Are we making progress?
And what is impeding progress ?
![Page 24: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/24.jpg)
The European Library to release
>115m bibliographic records to be released as
CC0 this year (2013)
Working with RLUK to release members’ metadata as linked
data
API and Linked Data to be published this year (2013) as well
![Page 25: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/25.jpg)
22m+ metadata records released as CC0 by Europeana c.2,200 institutions
![Page 26: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/26.jpg)
Some of largest cultural datasets in
the world
Hooray !
![Page 27: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/27.jpg)
but ...
![Page 28: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/28.jpg)
Cool URIs
![Page 29: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/29.jpg)
97% of links resolve properly
![Page 30: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/30.jpg)
660,000 (c.3%) of records have broken
links
![Page 31: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/31.jpg)
Licencing
![Page 32: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/32.jpg)
64% of records do not come
with clear licensing about
the content
![Page 33: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/33.jpg)
a good example
![Page 34: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/34.jpg)
Current licence distribution in Europeana(end of 2012)
Europeana has launched a rights labelling campaign to improve this
![Page 35: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/35.jpg)
and even when metadata is
technically well formed ... it might
not help user discovery
![Page 36: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/36.jpg)
Quality of metadata ?
![Page 37: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/37.jpg)
User path ?This example leads to the
user to a copyright message in German, then then the jpeg without any
metadata
![Page 38: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/38.jpg)
![Page 39: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/39.jpg)
Lack of context ?
Again, the user is led to a jpg without any
explanation of the image
![Page 40: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/40.jpg)
Multiple records for one item
![Page 41: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/41.jpg)
The perils of basic search
![Page 42: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/42.jpg)
And of course semantic differences
![Page 43: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/43.jpg)
Much of this is ‘basics’ - licencing, permanent URIs,
quality of metadata intelligent URIs
![Page 44: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/44.jpg)
More complex issues such as semantics and
clustering of records and relevancy ...
... are being addressed by the Europeana Data
Model
![Page 45: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/45.jpg)
no point aggregating if you can’t reuse
![Page 46: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/46.jpg)
for europeana and TEL, finding re(users) is critical
![Page 47: Breaking the Waves](https://reader036.fdocuments.in/reader036/viewer/2022081400/554bc87ab4c90530298b5730/html5/thumbnails/47.jpg)
