Hello,
We've been working on integrating some external databases in the Query Service endpoint. You can now query in the same time Wikidata and other free knowledge bases. For now, only databases released under the most compatible licenses, such as CC0, are available. Currently available:
* Europeana[1], the huge collection of cultural data, which is entirely available in public domain. * Nomisma.org[2], a collaborative project to provide stable digital representations of numismatic concepts. * Biblioteca Virtual Miguel de Cervantes [3] * Biblioteca Nacional de España [4]
Soon, we plan to also enable querying other databases, with licenses such as CC-BY. We plan to continue add endpoints based on user requests.
The currently available endpoints are listed here: https://query.wikidata.org/copyright.html
The documentation about the feature (which will also be updated when we add more endpoints) is in the Query Service User Manual [5].
Here are some examples to understand how to build such queries: https://www.wikidata.org/wiki/User:Smalyshev_(WMF)/Federation
Thanks a lot for your input! If you have any question or problem, feel free to contact me.

Hoi, Would it be possible to include DBpedia as a matter of urgency. They added the cc-by-sa because at that time wisdom was to have the same license as Wikipedia to prevent upset people. Given the strong relation between what we do in our projects and what they do in theirs it is easy to come up with user scenarios that will benefit both our projects. Thanks, GerardM

Hi Stas,
Can I assume the brief waiver by the UniProt PI to not be sufficient for allowing even the federated use in WikiData of sparql.uniprot.org. If that assumption is correct I will restart the long UniProt internal struggle to get that fixed.

Frankly, I am not sure what to do with this. The ND part is kind of concerning, and I'm not a lawyer so I am not even sure I understand it properly. While it looks like the "BY" part can be satisfied with https://query.wikidata.org/copyright.html type page, the ND part still remains and I'm not sure how to deal with it. The letter answer is great and I am thankful for it, but what I am concerned about is how to make it the matter of record - in 5 years, maybe both myself and person who wrote this letter would forget about it, and the system still needs to be maintained. So if there were some statement on official UniProt docs that says this case is OK (within some kind of FAQ probably? Maybe http://www.uniprot.org/help/license ) or somehow a way to make an official permission (some kind of letter to legal@wikimedia.org? I don't know, I don't have much experience with this) that would make it much easier.
This is a wonderful and most welcome development.
What is the process for getting a query service added? I would like to add the Librarybase endpoint, http://sparql.librarybase.wmflabs.org/, but I want to make sure that it meets all the requirements.

Hi!
What is the process for getting a query service added? I would like to add the Librarybase endpoint, http://sparql.librarybase.wmflabs.org/, but I want to make sure that it meets all the requirements.
Right now it's https://www.wikidata.org/wiki/Wikidata:SPARQL_federation_input. After we're done with CC-By ones, I'll probably clean up that page a bit and update it for more long-term structure but it seems something like that would work.
Hi!

I understand the reason for CC-BY in DBpedia, and it looks like adding it to the license/copyright/acknowledgment page should be enough. I planned from the start to launch it with small number of endpoints and then extend it. I plan to see how it fares and if there's not anything wrong that we've missed (doesn't look like it so far, which is good) and add next batch next week - which means it would be deployed in April 10th deployment window (we deploy WDQS stuff on Mondays usually).

Stas,
You can also add the SPARQL endpoint associated with our URIBurner service. This service will also allow you to nest SPARQL-FED Queries.

Stas,
Some sources of SPARQL Endpoints that could be of interest:
[1] https://del.icio.us/kidehen/sparql_endpoint
[2] http://linkeddata.uriburner.com/sparql?default-graph-uri=urn%3Asparql%3Aendp... -- SPARQL Query Results page listing some of the endpoints in the LOD Cloud
That is a great news!
How about adding an ODbL licensed service? Would it be possible? I am thinking about SPOI http://sdi4apps.eu/spoi/ and their SPARQL endpoint http://data.plan4all.eu/sparql..

We don't control that service. By default, Virtuoso Open Source Edition SPARQL endpoints are typically CC-BY-SA.

Great new feature you have here! I would only add endpoints that use free licenses that are compatible with our terms of use ( https://wikimediafoundation.org/wiki/Terms_of_Use#7._Licensing_of_Content ). See http://freedomdefined.org/Definition for a more general explanation. This would include ODbL ( https://opendatacommons.org/licenses/odbl/summary/ ), but would exclude any ND (NoDerivatives) and any NC (NonCommercial) licenses.

Hoi, What I fail to understand in this discussion about licenses is what it is we achieve by being restrictive.
Our license is CC-0 so anybody can do with our data as they please. When we allow query with any and all external sources, there are activities that may not be possible because of a license. What are they?
When people link Wikidata and compare values, finding a difference is imho not licensed because it is original research. When people link Wikidata and add Wikidata statements elsewhere, it is allowed because of our license. When people link Wikidata and add items or statements to Wikidata only then there is a reason to respect the license of the external source and disallow it. I can imagine that we disallow update statements in Wikidata based on the license of the external Source.
For all other objectives it is the user who is responsible for his actions. Not allowing this is imho contrary to our motto: "sharing in the sum of all knowledge". Thanks, GerardM
