[ckan-dev] OpenSearch

Wed Feb 3 14:05:22 UTC 2016

Hello Pedro,

They fire up at the following events of a dataset lifecycle:

* after_update
* after_create
* after_delete

These hooks are provided to any plugin declaring that implements
`IPackageController` interface.

See, for example:
https://github.com/PublicaMundi/ckanext-publicamundi/blob/master/ckanext/publicamundi/plugins.py#L680
