Re: Forms Task Force members (roll call and call to action), Fw: Architectural Consistency - What does it mean?

I agree our working group has certainly been working very hard to get to 
the point where we have an idea of what and how to contribute to the 
results of the task force.

In an ideal world, it might have gone somewhat faster for the TF to have 
developed more of what we have now, but I think it would have been esp. 
hard because the TF doesn't even seem to agree on the right level to do 
the thinking AND it really took the union of all our brain powers to 
figure out the thing we have now anyway.

But as of yesterday, I really felt we had enough worked out to go forward 
with, and the HTML WG participants legitimated my thinking that we have 
not gone too far without pulling them in, so now seems to be the right 
time to get re-engaged.

So I've heard from you now, and want to know whether Nick and Sebastian 
will also be able to do some work on a weekly basis to get some kind of 
output from this task force.

Hi John,

I've made clear on the telecon and in a couple of emails to the TF that 
our 'activity' was predicated on some agreement from the XForms WG on what 
simplification means.

So, yes, it's exciting that the WG has got some agreement on that, and 
that we can now get 'active' over here in the TF. But I'd hate for anyone 
to think that the lack of activity was down to myself, Nick and Sebastian. 
:)

Regards,

Mark

We now have some concrete ideas that can be used to develop *some* kind of 
reasonable output from the task force. 

I also received the following message (part of a larger message in 
www-archive) from a co-chair of the HTML WG (Dan C.): 

(1) I think the line between syntax and architecture is
blurry at best, and I don't consider it out of order
to discuss specific syntax proposals. I'm not sure
that's the main objective of the task force, but
I can imagine cases where it's helpful.

(2) While many have observed that the current task force
organization hasn't produced all that much, I'd like
to give it a try for a at least a few more weeks.

Now is the time for the three of you to become active on this TF.  Please 
let me know *whether or not* you can do this.

Architectural Consistency - What does it mean?










In the interests of making a positive contribution to the Task Force:

"Architectural Consistency" is a pretty broad term. One thing we 
should decide as a Task Force is what sense we intend it in.

Here are some possible ways of interpreting "architectural 
consistency" between multiple forms technologies:

1) Both are consistent with the Web architecture as a whole (in other 
words, URIs for addressing, documents described as markup, REST 
architecture model, etc).

2) Both may be used together on the same Web site without conflict.

3) Both may be used together in the same Web document without conflict 
(for example, through use of XML namespaces to disambiguate).

4) Both are reasonably aligned in their capabilities where they 
overlap, without gratuitous differences.

5) One may be implemented in terms of the other through a prior server 
side translation (this would be a scenario such as "author in XForms, 
translate to HTML Forms for client-side deployment").

6) One may be implemented in terms of the other through client-side 
script-based support (for example, XForms-like markup is sent to the 
client along with a script that translates the mechanisms to HTML 
Forms and implements the processing model).

7) Both must be describable in terms of a single server-side 
processing model.

8) Both must be describable in terms of a single client-side 
processing model.


I would argue that 1-7 are all reasonable expectations for 
architectural consistency. As an example, SVG and HTML would satisfy 
criteria 1-3 and 5-7, and 4 is debatable (there is some overlap in 
areas with differences but it is in dispute whether this is necessary 
or not, and the groups are working on closer alignment).

I would argue that #8 is too strong a requirement. For example, CSS 
and SVG have completely different models for layout. But because there 
are defined ways to interoperate, it is not generally argued that this 
makes them architecturally inconsistent. Similarly, http and ftp are 
completely different protocols from the client's perspective. But 
shared URI addressing and the request-response model bring them into 
an architecturally consistent whole.


Any thoughts from other Forms TF members? Are there other criteria 
that you would see as part of "architectural consistency"? Mine are 
all pretty general to the Web and not very specific to Forms.

Regards,
Maciej
