If so, what exactly is the format. I guess it's not the media-type (e. g. RDF/XML, Turtle, ...) but something more like an RDF Shape [1]. I think we need to interact with the W3C data shape WG on this. There has been some discussion on shape negotiation on the LOD list [2] that I sparked off a few weeks ago, but there has been no consensus on the matter yet. > > [1] http://www.w3.org/2014/data-shapes/ > [2] Long thread starting at https://lists.w3.org/Archives/Public/public-lod/2015May/0034.html > > Best, > > Lars > FWIW, in OGC we use MIME types indeed for the coverage formats (such as "image/tiff") -Peter -- Dr. Peter Baumann - Professor of Computer Science, Jacobs University Bremen www.faculty.jacobs-university.de/pbaumann mail: p.baumann@jacobs-university.de tel: +49-421-200-3178, fax: +49-421-200-493178 - Executive Director, rasdaman GmbH Bremen (HRB 26793) www.rasdaman.com, mail: baumann@rasdaman.com tel: 0800-rasdaman, fax: 0800-rasdafax, mobile: +49-173-5837882 "Si forte in alienas manus oberraverit hec peregrina epistola incertis ventis dimissa, sed Deo commendata, precamur ut ei reddatur cui soli destinata, nec preripiat quisquam non sibi parata."
