Transactions

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.

Note

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.

Harvesting

Note

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.

Transactions

pycsw support 3 modes of the Transaction operation (Insert, Update, Delete):

• Insert: full XML documents can be inserted as per CSW-T
• Update: updates can be made as full record updates or record properties against a csw:Constraint
• Delete: deletes can be made against a csw:Constraint

The Tester contains CSW-T request examples.
