I'm currently working on a GTD orientated client for Windows and plan to include functionallity to synchronise Contexts/Projects/Actions which will, most likely, import and export an XML file containing the relevant data.
I am wondering if anybody here knows of an already-developed standard/format for this? If something could be agreed on then these files could, in theory, be syncd. across multiple clients and platforms.
Any information would be great appreciated! Cheers.
