Hi,

I repeated the FED using:

[1] http://linkeddata.uriburner.com/sparql


The SPARQL Protocol URL is:

The error message from my system is:

Content Encoding Error

The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.

    Please contact the web site owners to inform them of this problem.


Then i slightly modified my FED this time using another SERVICE specification to connect to our SPARQL endpoint service because i was not sure if the query from [1] need that. The SPARQL Protocol URL is:

http://linkeddata.uriburner.com/sparql/?default-graph-uri=http%3A%2F%2Frdf.disgenet.org&query=PREFIX+atlasterms%3A+%3Chttp%3A%2F%2Frdf.ebi.ac.uk%2Fterms%2Fatlas%2F%3E+%0D%0APREFIX+sio%3A+%3Chttp%3A%2F%2Fsemanticscience.org%2Fresource%2F%3E%0D%0APREFIX+ncit%3A+%3Chttp%3A%2F%2Fncicb.nci.nih.gov%2Fxml%2Fowl%2FEVS%2FThesaurus.owl%23%3E%0D%0ASELECT+%3Fgene+%3Funiprot+FROM+%3Chttp%3A%2F%2Frdf.disgenet.org%3E+WHERE+{+++%0D%0ASERVICE+%3Chttp%3A%2F%2Frdf.disgenet.org%2Fsparql%2F%3E+{%0D%0A%3Fgda+rdf%3Atype+sio%3ASIO_001123+%3B%0D%0A+++++sio%3ASIO_000628+%3Fgene%2C%3Fdisease+.%0D%0A%3Fgene+rdf%3Atype+ncit%3AC16612+%3B%0D%0A++++++sio%3ASIO_010078+%3Fprotein+.%0D%0A%3Fdisease+rdf%3Atype+ncit%3AC7057+.%0D%0A%3Fprotein+skos%3AexactMatch+%3Funiprot+.%0D%0AFILTER+regex%28str%28%3Funiprot%29%2C%22purl.uniprot.org%22%29+%0D%0A}%0D%0A%0D%0ASERVICE+%3Chttp%3A%2F%2Fwww.ebi.ac.uk%2Frdf%2Fservices%2Fatlas%2Fsparql%3E+{%0D%0A%3Fprobe+%3Chttp%3A%2F%2Frdf.ebi.ac.uk%2Fterms%2Fatlas%2FdbXref%3E+%3Funiprot+.%0D%0A}%0D%0A}+%0D%0ALIMIT+20&should-sponge=&format=text%2Fhtml&CXML_redir_for_subjs=121&CXML_redir_for_hrefs=&timeout=30000000&sid=

A Few things:

1. there's a URI shortener service at <http://linkeddata.uriburner.com/c>
2. you can also share query definition by changing &query to &qtxt .

An example of a shortened query definition URL: <http://linkeddata.uriburner.com/c/9D6JOWB7>

At this point in time, the SPARQL endpoint at <http://rdf.disgenet.org/sparql/> isn't working . That skew this entire exercise.

Many thanks!

Hi,

When i query another sparql endpoint from our endpoint (using SERVICE) i
got in Firefox the 'Content encoding error' problem. I checked the
virtuoso.log error file but there is nothing related written down. Do
you know how could i trace or solve that problem? Many thanks in advance.

We are running virtuoso version 07.10.3207, on Linux
(x86_64-unknown-linux-gnu), Standard Edition

Best regards,
Núria

Please repeat your SPARQL-FED attempt using our URIBurner instance [1].
Then share the SPARQL Protocol URL either way. This aid problem
investigation and resolution.

Also include the error message from your system.
