I have finished development of the first plasmoid to interface with the Open Build Service (OBS). The plasmoid takes the input name of a project, fetches the Build Results from the OBS API, and displays the Build Results in the format:

repositoryname-architecture-packagename   code

The OBS username and password is stored using KConfig. The next plasmoids I am going to be working on is to retrieve the list of requests from the API.
