Here's a little side-project I've been working on this past week and a half.
mapguide-rest is a PHP-based web extension for MapGuide that provides:
a) A RESTful interface to the MapGuide Web API (continuing ideas explored
in the defunct mapguide4j project also on my github)
b) A re-imagining of GeoREST's data publishing capabilities.
Because it is PHP-based, it will also work on Linux builds of MapGuide as
well and installation is a simple drop-the-folder-into-the-www-directory.
mapguide-rest has been tested on MapGuide Open Source 2.5.2, but should
theoretically work with any version of MapGuide/AIMS that bundles PHP 5.3
or newer. However, there may be bugs in the MapGuide API of these older
versions that may prevent some parts of the REST API from working properly.
