@acoburn, true, I saw that difference. the API described algorithm and the most recent (a bit flawed HTML) specs speak about flattening as a separate process, which via a consecutive process can be left expanded of compacted depending on if a non-null context is passed or not.
What makes me wonder is this line
JSON-LD's media type defines a profile parameter which can be used to signal or request flattened document form. The profile URI identifying flattened document form is http://www.w3.org/ns/json-ld#flattened. It can be combined with the profile URI identifying expanded document form or compacted document from.
From http://json-ld.org/spec/latest/json-ld/#flattened-document-form
Which somehow suggest that we should be combining profiles, but does not state what should be the default behavior? I agree on this
but I would gladly take a W3C recommendation over a namespace/vocabulary document any day,
but I don't see the W3C recommendation to be very clear on the default behavior, if I'm asking via a header that I just want "flattened"
or even how combine.
I do realize (thanks!) that http://www.w3.org/2001/XMLSchema is not the standard way, (but still valid in this case... uff, I will paste this with regrets.. http://www.w3.org/TR/cooluris/) and that we are more used to common and expecting the no document representation via http://www.w3.org/2001/XMLSchema# but the issue here is that the URI compacting algorithm is indeed (outside the fact that there is redundancy here) splitting on "-" in an maybe arbitrary way? at least to my knowledge dash symbol have never been a way of referencing properties (fragments) of a parent namespaces or have any meaning at all.
I really appreciate the time you took to answer my questions. really. good night

@DiegoPino to further complicate matters, the JSON-LD namespace document (published in Feb 2013) defines the following forms:
The JSON-LD specification (published Jan 2014) defines the following three profiles:
The JSON-LD spec makes no mention of
http://www.w3.org/ns/json-ld#compacted-flattenedorhttp://www.w3.org/ns/json-ld#expanded-flattened. It is, perhaps, worth noting that the JSON-LD vocabulary resource is published as flattened JSON-LD with a non-null@context-- thus:compacted-flattened.The main point here is that the difference between expanded-flattened and expanded-compacted relates to whether the
@contextis null or not -- there are no other structural differences.And as for how Fedora behaves, it uses its namespace definitions to populate the
@context, which is how it populates the namespaces for every RDF serialization other thann-triplesand expanded JSON-LD (both of which have no notion of namespaces -- all the other forms have optional notions of namespaces). So, in terms of consistency, I would argue that the current behavior is consistent with how other RDF serializations work.So, I agree that there is some ambiguity here, but I would gladly take a W3C recommendation over a namespace/vocabulary document any day, especially a W3C spec that was published after the vocabulary document.
What does strike me at strange is the use of
"xsi":"xs:-instance"-- that does seem weird. But that seems more an issue with the presence of"xs":"http://www.w3.org/2001/XMLSchema"instead of the more typical"xsd":"http://www.w3.org/2001/XMLSchema#". Personally, I'd just remove thexsprefix from the representation -- I don't know how that's getting set, but it seems unnecessary. But that's a completely different issue from the question of flattened JSON-LD.
