> So what makes Hydra collections context-specific that doesn't make RDF lists context-specific? > What aspects of the design worry you exactly? Pages, for example. The way I see it, "Page" is an abstraction of "Range". The latter is way more universal than the former, at least IMHO. But that's not a problem, really. As long as I have my basic building blocks to work with, everything else is a plus that does not hurt. I would just move it to a dedicated project as think it's not as basic and universal as the rest of Hydra. > It's easier for people (and machines) to understand these things if they are expressed explicitly instead of relying on implicit assumptions or inferences. Agreed. > I see. So, you still want to give the collection itself a URL, right? In that case, the simplest JSON shape for the collection looks somewhat like this [...] > Do you have something that you can share with us? I'm highly interested in what you came up with. Well... Yes, unless I use the "describedBy" IANA rel in a Link header. I'll do my best to come up with something for you to have a look at over the next days but the gist of it is that I'm using "describedBy" to point to a document that describes (in Hydra terms) a collection (or the range of a collection) presented as a simple JSON array. A (admittedly very dirty) nodejs proxy takes care of joining the collection itself and its description into a single document that the Hydra console can work with. I'm also using the "@reverse" trick and the following: ex:Range --> ex:rangeOf --> ex:Collection ex:Collection --> ex:hasRange --> ex:Range ex:Collection --> ex:total --> int ex:Range --> ex:start --> int ex:Range --> ex:end --> int ex:Collection --> ex:subject --> foaf:Person (or whatever) ex:Collection --> ex:predicate --> foaf:knows (or whatever) I might be using "describedBy" in the wrong way but the method itself seems to work. > P.S.: Text-only mails are generally preferred on mailing lists. Thanks :-) Ops. Sorry about that. Will do better.
