Following the call last week, I have made some updates to the "Syntax for Tabular Data on the Web” document at



  * I have separated out three levels of data model:
    * a core data model which is just tables/columns/rows/fields
    * an annotated data model in which each of these can be annotated
    * a grouped data model in which there are multiple tables in a group

  * I have stated that the ordering of columns is significant in the core data model

I have defined the annotated data model extremely loosely: it just says that tables, columns, rows, fields and regions can be annotated, but it doesn’t say anything about what those annotations might look like (eg that one of the annotations might be the *type* of a value). I think the direction I’d like to take that is to retain this very loose definition and then state that there are certain annotations (eg 'type', 'unique') that are understood by particular types of applications (eg validators, converters) in particular ways. Does that seem like a reasonable approach?

I haven’t made any attempt to tackle the syntax for annotated or grouped tables as yet.
