OAI-PMH - stefan, why don't we want to require GetRecord ??

Interfaces

My current thinking is to separate out interfaces for different classes of data search / retrieval tasks. E.g. many people are more interested in repositories of information about web services. They want to do realtime access "find-bind".

Other people are more interested in the publish side - real data syndication between repositories - the kind of thing that OAI-PRE will one day support. In the meantime we have to make something out of what we have got. Jeroen writes,

For the harvesting of the catalog itself, GeoNetwork has a custom
interface/ process. This process will go out to some XML service
(provided by another GeoNetwork node at this stage) and will request
a very brief result set from the other catalog that contains file
identifier (UUID), time stamp and catalog ID.  By comparing those
with its internally cached records it will decide to request new or
updated records and it will remove those not found anymore.
