[dais-wg] OO Realization

[Norman Paton]

Here are a few comments on the initial draft:

Page 1: The editor list is too long!  In general, one is named on the 
front page of DAIS specs as a result of sustained contribution to a 
document or the discussions relating to its contents.  As this is 
currently your document, it should just name you on the cover for now.

Page 6, Line 182: JD-OQL as one of the query languages. I am conscious 
that JDO-QL queries are normally represented as Java objects, so it 
needs to be stated how these are represented as parameters to a message. 
If this was an XML structure, then it may be quite straightforward to 
support this over existing platforms that don't support JDO-QL directly.

Page 9, Line 263: Representation of references to objects.  One might 
expect this to be some form of wrapper type that states something about 
the source of the reference.  The spec would then need to state some 
properties of instances of the wrapper type.  One might expect that the 
main or perhaps only guarantee is that the reference can be passed as a 
parameter to some operations on the service whence it came, where if the 
object still exists and appropriate permissions exist, further behaviour 
can take place.

Page 9: Line 267: Result format: This seems never to contain the values 
of properties of the objects, in the way that WebRowSet contains the 
values of the tuples.  There needs to be some representation for the 
values of the objects too - are there existing candidates?  I note that 
a message could contain a parameter that states how deep a copy of the 
properties of an object should be returned.
