Sebastian,
Is there a document/paper that summarizes the rationales, vision, and
technical details behind DBpedia's Databus. Also, since a few other
companies already tried to recombine and publish structured data in a
more principled way before, what is different here?
these are legit questions. If you mention other companies, I would start
to wonder which ones exactly. I chatted with Jamie Taylor about Freebase
and he agreed (or maybe just wanted to be nice...) that we are solving
many aspects which were flawed there. Do you know of any other
successful models? I would need to know specifics in order to compare.
We basically took the top of the cream of what was developed over the
last years and discussed models that would incentivize open data as well
as bringing in the money to maintain open data. The system here is
fundamentally different from any approach that copies and aggregates
data. I know that nowadays you would hear the sentence "we built a
pipeline" in every other presentation. But data is not oil and one way
pipelines do not make sources better.
Since we are "alpha" there is no documentation yet, but we are
developing the whole system with around 10 organisations at different
ends of the databus. The data is available already for download.
So basically...
where you get "compute" heavy (querying SPARQL)... you are going to
charge fees for providing that compute heavy query service.
where you are not "compute" heavy (providing download bandwidth to
get files) ... you are not going to charge fees.
The latest read is the handout for Europeana Tech, which should clarify
this point:
https://docs.google.com/document/d/1OkHBpvQ0h5Qnifn5XKYVV2fiMjsdaooNg1iqS4rCRHA/edit
I was more expecting technical questions here, but it seems there is
interest in how the economics work. However, this part is not easy to
write for me.
All the best,
Sebastian
Cheers.

Is this a question for Sebastian, or are you talking on behalf
