[ckan-dev] harvesting csw

[David Read]

Armin,

1. On ckanext-spatial there have been some model incompatibilities on
the master branch last week which you may have caught. Update to
latest (c6ac949) and retry. If it is not that, then check your fetch
paster command-line specifies the correct CKAN config file. If still
not working, send us the exception, providing more info.

3500 XML files shouldn't be more than an hour or so, I'd have thought.
Each one requires one request to the GeoNetwork server, store in the
database, retrieved from the database, XML parse and validation and
storing as a CKAN package in the database. The limiting factor is most
likely the CSW get from your server.

2. All changes are tracked, like any wiki, and to enable you to
'undelete' a deleted dataset, so the name is reserved going forward.
Hopefully Options:
* Try doing an undelete (with package_update, I guess)
* Purge the old one and recreate - not possible since purge API has
not been made (shame) http://trac.ckan.org/ticket/1832
* Before deleting the old one, rename it out of the way.
