Kingsley,

Thanks for your support. All data available through the SPARQL endpoint is
compliant to this vocabulary:
http://labs.mondeca.com/vocab/endpointStatus which
relies on VoID . What Robert suggested me is to integrate RDFa in RSS feed
which is a great idea.

I will for sure improve the endpoint accessibility for humans.
