There are a few paragraphs in the current spec ( http://www.w3.org/2012/ldp/hg/ldp.html ) which seem to need a bit of clarification, relating to ISSUE-15 probably. I am just noting it here, as I am thinking about this right now, and noticed these. It is also related to use cases 4.8 and 4.8.1 of the UCR http://www.w3.org/2012/ldp/hg/ldp-ucr.html#uc-manage_media_resources Definition: [[ Linked Data Platform Resource (LDPR) HTTP resource that conforms to the simple lifecycle patterns and conventions in this document. ]] So presumably resources that can be created in a collection and that get deleted when a collection gets deleted. If we add images to a collection, are they then LDPRs? [[ 4.1.3 LDPR servers may host a mixture of LDPRs and non-LDPRs. For example, it is common for LDPR servers to need to host binary or text resources that do not have useful RDF representations. ]] This seems to suggest that LDPRs cannot be binaries. [[ 4.2.2 LDPR servers must provide an text/turtle representation of the requested LDPR. ]] If one were to create a picture, would this say that one MUST return turtle for it by default? That would not be completely silly it could be a representation of the picture that said something like: ------------------------------ @prefix iana: <http://www.iana.org/assignments/relation/> . @prefifx foaf <http://xmlns.com/foaf/0.1/> . @prefix awol: <http://bblfish.net/work/atom-owl/2006-06-06/#> . <> a foaf:Picture; foaf:depicts joe, jack, jane; iana:alternate <image.jpg>, <image.gif> . <image.jpg> awol:type "image/jpeg" . <image.gif> awol:type "image/gif" . -------------------------------- But that still leaves the question what happens if one GETs <image.jpg> without an image/* mime type. Does one get a redirect to the previous metadata file served as Turtle? Or does the server just return the image? And if one deletes the collection, does <image.jpg> not also get deleted?
