I'm currently the only developer that I know of working on the MythXML
interface. I have major changes to it waiting on my machine for the current
release to be completed. Once the freeze is lifted, I'll commit my changes
and it should be relatively easy for you to make your needed changes.
The only thing you will need to do is think through the list of features you
want to implement (Some of them may be available in the CDS (Content
Directory Service) already implemented). I don't want this interface to be
flooded with every specialized method anyone can think of. The methods
added should be well thought out and represent a set of functionality that
will be usable to all potential frontends.
The nice thing with my new design, is that the methods are just standard
methods (in this case part of a new class called MythApi) that return normal
QObject based data classes (defined in a new datacontracts.h header file).
The method invocation, and response serialization has all been abstracted
out so you don't need to concern yourself with how the data is transmitted
over the wire (ie: xml, SOAP, json, ...).
