Abstract
cover services, .operations file, .operations dtd spec, perhaps make a service like the pastebin one or something. idk, something easy.
http://www.kde.org/standards/kcfg/1.0/kcfg.xsd
also mention how a service can access the dataengine via it's pointer(I think that's in public api), if it really really needs to(e.g. plasma-kdm can't live without that)
The Plasma Engine Explorer
A very useful tool for anyone writing services is the Plasma engine explorer. You can use it to see test services by launching them by running
plasmaengineexplorer
If the service you want to test is associated to a source, you can access a dialog to launch the service and set its parameters by using the contextual menu of the source and selecting "Get associated service"
The Code
This tutorial will cover adding a service associated with a source into an existing data engine.
