One reason for title only feeds is to address bandwidth limited devices. The
server I set up provides the same feed in two different formats - one title
only and the other with title/summary/etc. The end client can decide which
feed it wants to work with based on its capabilities; however, both feeds need
to be Atom spec compliant. The only thing needed for interop is some minimal
useful information to indicate what the entry is (Title), the ID to identify
uniqueness and a time stamp (updated) to indicate time ordering. Everything
else simply adds more richness to the entry; some may be used by the end
client and some may not. For example, sending entries with summarys may not
be of any value to a device with limited display/storage capabilities, so why require
it when it only chews up transmission bandwidth? Brett Lindsley, Motorola Labs.
