Comment on Probing the SPARQL endpoint of data.gov.uk by li

very cool. Just ran my script to probe it

http://services.data.gov.uk/sparql 5M triples, 99 classes, 86 properties live test
http://services.data.gov.uk/transport/sparql very big, timeout in most cases
http://services.data.gov.uk/education/sparql 6M triples,41 classes, 186 properties, 2258 named graphs live test

Hi,

Thanks for posting this, an interesting experiment!

There are actually several SPARQL endpoints. The one you’ve been playing with doesn’t yet contain all of the data we’re hosting. It currently has some information from the London Gazette website, but will ultimately contain the full UK dataset.

There will be a number of different SPARQL endpoints organized around particular areas, e.g. education, transport, crime, etc. There is data in the education and transport stores currently:

http://services.data.gov.uk/transport/sparql
http://services.data.gov.uk/education/sparql

We also have plans to publish VOID descriptions of the datasets as well as additional directory information.

Cheers,

L.

yes. We have a script running doing the job now. Expensive queries are still problems, but that may be solved by using only lightweight queries and leverage timeout mechanisms.

It is PHP based, and the source code can be found at

Very interesting.

Would it be possible that you publish this as a kind of script for access point providers to check their data?

thanks for the comment. The government ontology (http://www.oegov.org/democracy/core/models/owl/oegov.owl) looks interesting. Do you have any plan to add rdfs:comment to the defined classes and properties?

Yesterday, August 1, I declared as “DataIndependenceDay”, following the Swiss some 700 years ago.
We published ontologies for oegov at http://www.oegov.us/blog. These are OWL ontologies for the organizational structure of government, FEA (coming soon) and QUDT, Quantities, Units, Dimensions and Data Types (coming soon). Data quality is a huge issue and QUDT is needed to help that.

I have made some properties for connecting to open data - who publishes what on what - something you are doing. Would like to understand how to make connections to your work, where our efforts can align in the interests of making semantic web technologies be more in awareness, appreciated and adopted.

In appreciation of your work, Ralph

Doh! Great job, great new!
I keep tracks of news concerning putting government data in the LinkedData, I tought the UK government will be faster (thanks to TBL mainly). Happy to see that the US community is translating non-standard formats into RDF.

Thanks.

Great Job. Lots of useful information may be gleaned from your great work. Are you also producing graphs of these data (linking information)? If so will that be in RGML format?
