Hi Adrià and Admins
Please see the OpenLink response below:
1) Open Link is no longer administrator for the DataStore (who is?).
2) CKAN has been hosting RDF datasets for years
3) The error is raised by the 'CKAN proprietary API ', data hub.io API
Can an administrator please try to upload the Code_Federal_Regulations.ttl. Do you get the same error?
It looks like the API is returning a wrong error code. There definitely are no extra keys in row 1. Can you see the original DataStore endpoint error code?
Thanks & regards

Note this online support site if for OpenLink commercial customers to which priority support is given ...
The http://semantic.ckan.net/sparql/ endpoint is something we hosted for the OKFN as part of of the LOD2 EU project (http://lod2.eu) we were partners with them in and host the metadata describing datasets hosted in there CKAN repository via the data hub.io API they provided for extracting it, and hasn't really been maintained since 2014.
It is not clear to me what the 409 error you are receiving has to do with the SPARQL endpoint though, as you seem to be seeking to input data into the CKAN repository, which is not done via SPARQL as it uses the CKAN proprietary API as far as I am aware i.e.
Error: CKAN DataStore bad response. Status code: 409 Conflict. At: https://datahub.io/api/3/action/datastore_create.
You indicate the "US_LegalReference.ttl, LegalReference.ttl" RDF file loaded successfully but the "Code_Federal_Regulations.ttl" failed . But the CKAN guy says there datastore only accepts files in tabular form, which seems odd has CKAN has been hosting RDF datasets for years to my knowledge ...
But they certainly are not uploaded via http://semantic.ckan.net/sparql/ which is just a read only sparql endpoint of the Metadata hosted in the datahub.io CKAN repository ...

Thanks a lot for your prompt response. I will revert back to DataHub support.
Indeed,the files were uploaded via the DataHub. So the issue must be with the hub.io API.I only use iSPARQL to query the data.
