   + Free Format data model fields and extensibility mechanism

When a data provider cannot use the proposed value fields (for instance in data product type), how can he/she still provide some information to characterise his/her data sets?

   1.How could we allow for extensibility?
     If we need to consider new kinds of science data product , not yet defined in the Obs/tap fields , how should we proceed?
   1.Description of a data set - __obs_title__

   In Obs/Tap , it is not a mandatory field, it could become important in future releases if its usage is well-defined. At the moment it is just free-format, and that could be an issue.
