*Hi Adam*,<br>
<br>
Where can I find more details about the architecture of Ur/Web "framework"?<br>
<br>
Almost every web framework on the market enthuses about the "MVC" pattern.<br>
Each of them forces in someway a separation of content, logic and view.<br>
For a traditional data centric web applications such a separation of<br>
concerns<br>
could be a huge advantage during development process.<br>
What is the ansatz of Ur/Web?<br>
<br>
As you surely know, there are also some growing tendencies<br>
towards SPI (Single Page Interface) and RIA (Rich Internet Application).<br>
For this sort of applications one needs a solid GUI toolkit.<br>
As far as I know there are two different approches for providing GUI:<br>
1) using a prebuilt JavaScript GUI toolkit wrapped in some APIs<br>
which in ideal case integrate seamlessly into the core framework<br>
2) [[a subset of the framework's core language) --> JavaScript]]<br>
compiler<br>
which provides the GUI toolkit<br>
<br>
The first alternative can be "easily" realized by taking some web framework<br>
and<br>
a decent JavaScript GUI toolkit like TIBCO General Interface, Javeline,<br>
dhtmlx,<br>
Qooxdoo, (to some extent flapjax) etc. and writing some glue codes!<br>
<br>
The second approach is more fundamental. To the best of my knowledge<br>
HOP and Links are the only frameworks that implement it properly.<br>
<br>
There are also Java oriented frameworks like ZK and Vaadin<br>
that follow a similar design concept.<br>
<br>
What about Ur/Web?<br>
Can Ur/Web also be used for RIA?<br>
<br>
Regards<br>
Nik<br>
