I have developed some web services code for moodle 2.2, respecting the web services roadmap at http://docs.moodle.org/dev/Web_services_Roadmap#API_Roadmap
I have published at first a series of patches on the respective issues, namely http://tracker.moodle.org/browse/MDL-30084? , http://tracker.moodle.org/browse/MDL-30082? , http://tracker.moodle.org/browse/MDL-30081? , but realized that the correct way of submitting code was using a git repository (by reading http://docs.moodle.org/dev/Quick_Git_start_guide_for_Moodle_development), so I have created it and published it at the issues, as a comment.
I am terribly sorry for the comment spam at the issues, but since I'm new around, I'm only now starting to learn the moodle development process
Anyway, I have developed the code for creating, deleting and getting the categories. I would like it to be reviewed and possibly integrated. I am developing a master thesis/project which will integrate moodle with other databases and category management is crutial for the project success.
What follows from here on?
