Hey there,
I've just completed a new proposal on the wiki for a new mechanism that
could be used to define a type definition for an object.
https://cwiki.apache.org/confluence/display/GEODE/Custom+External+Type+Definition+Proposal+for+JSON
Primarily the new type definition proposal will hopefully help with the
"structuring" of JSON document definitions in a manner that will allow
users to submit JSON documents for data types without the need to
provide every field of the whole domain object type.
Please review and comment as required.
