[seek-dev] Today's Ecogrid Call

[Rod Spears]

Thinks to think about before we meet:

1) The Eml200DataSource uses the Ecogrid to get Metadata about an item 
and then returns the data for that item as a single table. The 
QueryBuilder can be used to reduce the number of columns that are pass 
through the ports, but is not necessarily a require part of this data 
object.

2) What else will we be using the generic QueryBuilder for? Meaning what 
kind of data object will be returning more than one table that is not an 
Ecogrid Query?
    2.1) I think we have talked about this when the user will be 
accessing local data files; thru HSQL?  JDBC?
        2.1.1) If so, then how do they discover and get their local data 
into Kepler?

3) Do we need a more generic EcogridDataSource object that can execute 
generic Ecogrid Queries? And if so, do we need an Ecogrid Query specific 
QueryBuilder instead of a generic one?

4) Do we need a DiGIR Data Source object, or would this be covered by 
#2. If it was DiGIR specific than we could get data from node that may 
not be register???? (I am not sure)
