Re: [Evolution] Query Evolution's Calendar Data storage location

There's a whole API for accessing Evolution data - you need to look for
info on "evolution-data-server" - for 3.16 you'll find info here

  https://developer.gnome.org/eds/3.16/

To be honest this sort of question is probably more suited for the
Evolution-hackers list.

"3.x" is not a narrow enough specification. There were lots of changes
within 3.x, including API and data storage locations.

Not if the source is remote.  Using EDS has the advantage that it is
source agnostic.

Not only can you use the EDS API directly, but EDS is a DBUS client, so
you should be able to get calendar information that way as well. That
is after all how the Gnome calendar app gets its data.

But that is a problem - you will need to tailor things to a specific
version: Evolution evolves all the time with the storage locations and
APIs changing significantly.
