kauri forms model should be injected from an external file

[mpo]

possible strategies:

[1] use <script></script> tag

Note however that more then one form can be present on a page. This would suggest we have some agreed variable (e.g. at $.org.kauriproject.forms.pageforms) holding a (possibly growing) structure of {'id' : {/*formconfig*/} , ...}

The model and template of multiple forms on a page can then be matched up by id.

Extra add-to would be that we can even just auto-configure the forms base on this variable.

[2] use $ajax call

Other approach would be to only pass the reference to the form-model and let that be downloaded upon construction of the new Form(id, modeluri)

Async behaviour is somewhat tricky in this sense IMHO.

The form model should indeed better be a static file, separate from the page, which would bring the following advantages:

• ability to minimize it: speed improvements, but also removes comments that you might not like the whole world to see

• caching: form configs sometimes become hundreds of lines

• editing: the form model could be stored in a js file, which is much more comfortable to edit than js embedded in xml

• conceptual simplicity

One issue to tackle is that the fconf currently contains various URLs: the data submit URIs, but also selection control URIs. We should foresee the ability to inject context into that (is currently already the case?)

[mpo]

Could you clarify what you mean with context?
IIRC The data-uri currently is already seen as a uri-template.

I am thinking we should have an easy way to provide some page-scope variables to point to

• current locale
• the public URI of 'main' and other public restservices ('data' at least)

maybe we should just hook them up under the $.kauri namespace? (see #200)

And then provide some way for that context to be available in the uri-template context so the uri's can be written as

"{kauri.pagecontext.uri.data}/person/{id}?lang={kauri.pagecontext.locale}"

or something along those lines (just thinking out loud)
