The vodml-lite-mapping vs the current proposal

This alternative mapping syntax keeps the same basics as the current proposal:

• The mapping is located in a <VODML> block, child of <VOTABLE>.
• The mapping elements reflect the model structure.
• The <VODML> block starts with a list of implemented models.
• There is one <TEMPLATES> per mapped <TABLE>.
• There is one <GLOBALS> block containing data shared by the whole mapping.

There are however significant differences:

• This mapping syntax support directive for the clients which are not part of the model (e.g. aggregation request or data filters).
• The mapping as an explicit entry point, telling to the client what is the VOTable content.
• Processing this alternate syntax require for the client to apply rules not states in the VOTable itself.
