ISSUE-37: What is the LDP data model and the LDP interaction model?

LDP model

What is the LDP data model and the LDP interaction model?

State:
CLOSED
Product:
Linked Data Platform Spec
Raised by:
Erik Wilde
Opened on:
2012-11-16
Description:
Before the spec dives into any details about how things are done specifically in RDF or with HTTP, there should be a section in the spec that clearly describes the model that LDP is about, both in terms of fundamental resources, and interactions with these. http://lists.w3.org/Archives/Public/public-ldp-wg/2012Nov/0127.html was an attempt to take what RFC 5023 is doing and summarize it. Maybe we are not making the same design decisions, but we should have a clear model of what it is we are designing, and a good description of that model. Personally, I think AtomPub could have done a better way of describing their model, but there are many useful things you can read about without having to read anything about XML or HTTP.

Having such a model also should help us to make many of our other discussions more effective, because we wouldn't have to start from scratch, but could use this fundamental model as the starting point, and then start answering detail questions from there.

The proposal is to create an initial section in the spec that attempts to clearly describe the overall model of LDP, and the different aspects i enumerated in http://lists.w3.org/Archives/Public/public-ldp-wg/2012Nov/0127.html could maybe serve as an outline for the questions this section should answer (and the answers could of course be different from the answers AtomPub came up with).

PS: http://lists.w3.org/Archives/Public/public-ldp-wg/2012Nov/0130.html may be relevant for this issue as well.
