RE: About XUL, XAML and Laszlo

Hi,

 

After more examination of XUL, XAML and more recently of Laszlo It appears that XUL is not closely related to XAML, in fact, both systems are far from being close. I would say though that XAML is closer to Laszlo than to XUL.

 

These two systems even if close in terms of visual capabilities are different in terms of code packaging:

-          XAML requires a .net environment to be installed on the client but do not necessarily requires anything on the server side.

-          Laszlo requires an interpreter on the server side and the flash plug-in to be installed on the client. Millions of clients already have a flash interpreter installed on the client.

 

It seems that compared to W3C DOM model + HTML, Laszlo has the advantage to run the code in both Netscape/Mozilla and Internet Explorer environments without any modifications. This is not the case with “standard based” document designed in accordance with W3C specs.

 

A similar environment to Laszlo could also be developed in SVG using, for instance an SVG plug-in but there are no higher level declarative languages available. SVG itself is too low level to be an economical declarative language. I have not seen yet any environments resembling Laszlo in terms of functionalities on top of SVG. Does anyone know about any environment offering a declarative language on top of SVG?
