Flush RDF to Fedora

[dannylamb]

• Add web service to Crayfish that pulls content from Drupal and add it to Fedora
• Add camel connectors to poke said web service in response to queue messages
• Update Drupal rules actions to publish queue message in response to write operations

Newbie question: where will the queue that the Drupal rules emits into live? Is that a Drupal function that persists into the main Drupal db? Or can it reuse AMQ or other central messaging plant?

[whikloj]

I didn't think Drupal came with a queue out of the box. But I know that this can be configured to re-use any existing messaging plant that supports Stomp. The broker URL is definitely configurable under the base Islandora configuration screen and the queues for the various rules events that are emitted are configurable under each "rule's" configuration screen and passed to the Broadcaster

[ajs6f]

Okay, cool, then the flexibility is there. I will read further and see if I can figure out whether the Karaf AMQ facility is being used for this.
