+1 for JSON. I could do no better then what Andy has written eloquently.

However it's the model that is the important thing for me. | |In my view* there's a protocol, a data structure and an on-the-wire |format. | | - Like Alexis said, the protocol is "a sequence of behaviours" - how |the communication happens and is mediated. This is our set of verbs. |This is, for example, can be mediated by REST. | - The data structure is the model. This is how each noun is related to |each other and what attribute is part of what noun. Models can be |somewhat ephemeral, often expressed as programming language agnostic |UML, BNF, XSD or indeed using a programming language e.g. Java, C etc |(but then model portability is limited). | - On-the-wire format is what we're currently talking about (JSON, XML, |TXT). The raw output of our model. | |The latter 2 can be compared to a compiler - the model is the language |and along with a frontend, it generates an AST (an object graph). With |the object graph, it's easy to output binary machine code via a backend |on whatever platform required. This is similar to if I was to code my |model in say Java, instantiate an object graph and then render that |graph using any serialiser. For example using XStream[1] I can output my |model using XML and JSON (the machine code). | |So currently in my view there's consensus around a protocol - REST (hope |that's fair to say); consensus forming on data structures; confusion on |on-the-wire formats. | |If we don't finalise our data structures (model) we won't resolve the |on-the-wire format quickly. | |Andy | |* Apologies if this is stating the obvious :-) |[1] http://xstream.codehaus.org | |-----Original Message----- |From: occi-wg-bounces@ogf.org [mailto:occi-wg-bounces@ogf.org] On Behalf |Of Richard Davies |Sent: 07 May 2009 08:37 |To: occi-wg@ogf.org |Subject: [occi-wg] Votes: XML vs. JSON vs. TXT | |I'd like to conduct a straw poll of members on this list. | |Tim Bray wrote: |> 4.
