Web client development framework

This page describes the existing open source development frameworks for web applications, with the goal of identifying one that would fit our needs for the demexp web client.

Most of these frameworks follow the MVC model.

Moodlehttp://docs.moodle.org/en/FeaturesGPL??PHPMoodle is oriented towards building pedagogical web sites. However, it could be useful for the way it considers social constructionism: social group constructing things for one another, collaboratively creating a small culture of shared artifacts with shared meanings (see http://docs.moodle.org/en/Philosophy).

Some Frameworks that were not worth considering (e.g., based on Java, non-free, etc.) did not make it into the above list. Here they are:

More about Quixote

An introduction: http://quixote.ca/overview/paper.html

The Debian package (in main): http://packages.debian.org/stable/web/quixote

Good points about Quixote:

  • simple and small;
  • focused on the Python language (even for the template language).

Bad points:

  • no facilities to access SQL databases (but do we really need this).
