Reference implementations

[Matthew Graham]

Hi,

We're trying to define specifically what would satisfy the reference implementation requirement for an IVOA Spec in the context of a data model. The proposal is that: 

(1) If the DM has been described using VO-DML it can be validated as valid VO-DML

(2) An XML serialization of the DM can be validated 

so therefore is the combination of the two sufficient to demonstrate the validity and potential interoperability of the data model (which is the purpose of the reference implementations). 

	Cheers,

	Matthew
