Re: LODCloud SPARQL Endpoints Spreadsheet

Hi Claus, thank you for the prompt action. Very much appreciated.

The suggested process seems quite reasonable. Looking forward to
seeing the updates.

cheers,

Right now I only added online/offline checking, but in principle one can also just query the endpoints for features and emit service descriptions or query for dataset metrics and emit void.
