Transactions¶

‘push’ metadata into repository
pycsw does no application level backup/versioning

Note

Always optimize your database accordingly (pycsw-admin.py -c optimize_db, VACUUM ANALYZE, etc.) when making changes to the repository

Insert¶

inserts a record into the repository
- like insert into table values (...);
pycsw honours the identifier in the metadata
- if absent, pycsw sets identifier
example: https://raw.github.com/geopython/pycsw/master/tests/suites/manager/post/Transaction-dc-01-insert.xml

Note

Always ensure your metadata has an identifier

Update (full)¶

full update of metadata record
will update based on identifier found in XML
- if no identifier, pycsw will insert as a new record
example: https://raw.github.com/geopython/pycsw/master/tests/suites/manager/post/Transaction-dc-02-update-full.xml

Update (property)¶

partial update of metadata record(s)
- like update table set foo="bar"
you can apply an OGC filter to make updates on specific records
- like update table set foo="bar" where identifier=12345
example: https://raw.github.com/geopython/pycsw/master/tests/suites/manager/post/Transaction-iso-03-update-recprop.xml

Delete¶

deletes record(s) from the repository
- like delete from table where identifier=12345
example: https://raw.github.com/geopython/pycsw/master/tests/suites/manager/post/Transaction-iso-05-delete.xml
