Ok, I've used that one once... so I could give it a shot...

Do you mean the 0.3 format -
https://secure.wikimedia.org/wikipedia/en/wiki/Atom_%28standard%29#Atom_0.3_and_adoption_by_Google
or the 1.0 format?

Would of course be interesting to map fields to atom entries - I suppose
you could use fields that have the same names such as title, subtitle,
id, updated - but there are hierarchical elements: link, subelements
inside an entry... that would require multiple datasets in FPC
(something like the ADO.Net dataset concept that includes the
possibility of multiple tables, including parent/child relationships...

Scary.

Just to make sure I understand correctly - I'm still a Lazarus newbie -
there isn't support for such a parent/child tables kind of dataset
(group) in FPC/Lazarus/Delphi, is there?
(I did see an ftDataSet field type so maybe that could be a clue?)

Would you perhaps have an example of a dataset/table and the resulting
XML you want to see?
