[Seaside] [sagan] structure of metainformation

[Adrian Lienhard]

Hi Cees

Some time ago, I started to write some "form support" which is driven by a
simple metamodel. It defines type (like text, boolean, date but also
relationships), validationrules and label. By providing a metamodel, you
already have a functional form which is very useful for fast prototyping. It
does rendering the input fields, caching, validation and commiting changes
on success.
Currenty, I haven't had time to work on this further. For simple use, it may
already be useful. Validation rules are missing and maybe also some kind of
RenderingPolicies (but this is not so important for me). There are some
tests and a simple example (also in the test category). (The tests are not
running at the moment, also WATestCounter doesn't, because WATestCase seems
to be broken (?)).

You can find the sources at: http://swiki.netstyle.ch:8080/Adrian/8

If you look at it, I'd really like to hear what you think about it and what
you think could be done better!

Adrian

Avi,

We had a discussion quite a while ago on IRC re. the stuff I brewn on VW
for DataValue/Attribute; we were both unhappy about how the Attribute
hierarchy looked like, and discussed some ideas.

I could grab the IRC logs (BBIWY: I log all chats ;-)), but I'd really
like to know whether you have thought more about this and whether anyone
else here can come up with input.
http://swiki.squeakfoundation.org/sea/70 has some thoughs on the issue.

This weekend, in a happy burst b/c OmniBase finally runs in Squeak, I
copy-n-pasted most of the low-level persistence related framework code
over from VW (that level may be useful for other projects as well, I'm
trying to keep it completely apart from anything Sagan-specific). I
still need to add unit tests, and I'd like to have this thing worked
out, before I can move to the most interesting bit - domain code and
especially a security model.
