pycsw has the ability to process CSW Harvest and Transaction requests (CSW-T). Transactions are disabled by default; to enable, manager.transactions must be set to true. Access to transactional functionality is limited to IP addresses which must be set in manager.allowed_ips.
For transactions to be functional when using SQLite3, the SQLite3 database file (and it’s parent directory) must be fully writable. For example:
$ mkdir /path/data $ chmod 777 /path/data $ chmod 666 test.db $ mv test.db /path/data
For CSW-T deployments, it is strongly advised that this directory reside in an area that is not accessible by HTTP.
Your server must be able to make outgoing HTTP requests for this functionality.
pycsw supports the CSW-T Harvest operation. Records which are harvested require to setup a cronjob to periodically refresh records in the local repository. A sample cronjob is available in etc/harvest-all.cron which points to sbin/pycsw-admin.py (you must specify the correct path to your configuration). Harvest operation results can be sent by email (via mailto:) or ftp (via ftp://) if the Harvest request specifies csw:ResponseHandler.
pycsw support 3 modes of the Transaction operation (Insert, Update, Delete):
The Tester contains CSW-T request examples.
