    8484It is a moot question as to how much of this needs to be replicated from the granule content.  
    85  * BNL would argue that the spatio-temporal coverage should be the *union* of the  
    86 granule coverages (''need a tool to produce this''). 
    87  * The parameter coverage is a bit more complicated, because now we think we could have, 
    88 for example, temperature monthly means and temperature annual means in the granules. I think the only thing that makes sense is to aggregate the granule parameter summaries. ''In which case why bother? We can parse the granule content.''

    8987 * ''There ought however to be a consolidated lists of feature types present ... as well'' 
    9088 * The other elements seem appropriate.

     94 * The dgDataSet Type should allow 'Mixed' (as for example both model and obs may be included in a dataset). ''One assumes these are effectively booleans?'' 
     95 * I don't really understand dbBasicData and dgDerivedData. In particular, the basic data context is really about listing the feature types, but we think we have that elsewhere, and we have in the dgDataSet information as to whether the data is simulated or an analysis. The only other option is that the data has been processed (derived) in someway, in which case there is utility in providing links to underlying datasets ''but these ought to be DataEntities not data granules'' ... assuming that the detailsof teh derivation/processing are in the dpt, the links are all that are really needed. The choice of timseries, integration etc is redundant as that information exists in the feature type and phenomenon information.
