Dear Kingsley,


Thanks for your comment. Each query has associated a link to the Endpoint in the link names “Database” at the beginning. On the database link you will find all the queries associated to this endpoint, and a button “Show database info” where you can find the endpoint URL.


If you want, you can also provide us new endpoints once you are registered in the system: http://bioqueries.uma.es/suggest/endpoint


The endpoint suggestions are checked and added if they work properly.


Registered users can also register new queries for any of the endpoints present in our database.


We are next to release a new version solving some problems and cleaning the database of non-working endpoints or incorrect queries.

Dear Saleem,

I read your email, and I would like to share with you http://bioqueries.uma.es as a repository of queries in Life Sciences.


Hi Ismael,

Cool service!

BTW -- What SPARQL endpoints are associated with these queries? Basically, how do I locate PARQL endpoint(s) on a per registered query basis ?

Dear all,


Do you have federated SPARQL queries you use today or have used in the past?

Please e-mail them to us (via  <mailto:saleem.muhammd@gmail.com> saleem.muhammd@gmail.com), as text files or in any way you prefer, together with the URLs of the endpoints on which you’ve executed them.


Motivated by FEASIBLE [1] SPARQL benchmark generation framework, we want to design a customizable (in terms of queries types, number of queries, number of datasets etc.) federated SPARQL benchmark out of real queries log/use-cases. To this end, we are currently collecting real federated SPARQL queries from different domains, applications, and endpoints for analysis. 


Your help in this endeavour would be highly appreciated.

We'll be more than happy to collaborate and/or provide you with the detailed results of the study if you contribute. 


Your federated queries will also be published as RDF as part of the extended LSQ: The Linked SPARQL Queries Dataset [2,3]. 


Best Regards,


Muhammad Saleem
