Hello again,
I wanted to find out if it is possible to do an incremental harvest based
on only records that have changed?
I loaded approximately 200 datasets into GeoServer and then harvested them
into GeoNetwork. I loaded them all into a single category, as I have not
been able to figure out how to filter records from geoserver. I then
proceeded to edit each of these records to put them into the correct
category and some other minor edits.
Soon after I added a few new records into GeoServer and then ran the
harvest again but to my horror it deleted all the existing records and
replaced them with a fresh dump from GeoServer, which is not what I was
expecting.
I was hoping that only the new records would be added.
Is it possible to only harvest new / changed records rather than a
wholesale delete and replace?
Regards
Dean Howell

There is some other users requesting such changes to persist
categories/privileges while harvesting from OGC WxS services. That would
require some work which is not yet funded AFAIK.
BTW, the GetCapabilities does not indicate which layers was updated/added
so that's not easy to check. There is the updateSequence which may be used
in some case (eg. GeoServer) but only provide an information if there was a
change in the service or not (and not at the layer level).
