Phillip Eby (pje) and I have been discussing an intermediate data  
representation layer and API for Chandler, dubbed the External  
Information Model, which inbound and outbound items will pass through  
when being shared to a server or dumped/reloaded from disk.  A wiki  
page describing it is:

ExternalInformationModel

Having this layer isolates parcels from any external serialization  
formats, eliminates the need for the dump/reload format to be the  
same as the sharing format(s), and is also a step toward solving the  
schema evolution problem.  With this External Information Model  
defined, we can now look for sharing formats that can be translated  
to/from this intermediate form.
