Hi Kashyap,
sorry, I was busy! I did not find the time to install and deeply check all your
code.

I think it makes no difference. It is OK if the status is an object.
(collect 'tgs '+Item (db 'nm '+Tag "foo"))
or
(mapcan
'((Tag)
(collect 'tgs '+Item Tag) )
(collect 'nm '+Tag "foo") )

Doesn't the above 'mapcan' do that?

Yes, I would just write
(mapcar '((This) (: itm)) (collect 'nm '+Tag "BLUE"))
but using the advantage of 'collect', the following should give the same
result:
(collect 'nm '+Tag "BLUE" NIL T 'itm)
