Sharing content between Drupal multi-sites with RESTful and Feeds modules

At Oswego, when we decided to go with Drupal multi-site, one of the biggest drawbacks was the ability “out of the box” to share content between sites. But when you think of it, how much of Drupal works just as you’d like right out of the box? We looked at a few options but what we ended up settling on was a combination of modules that is doing the trick nicely.


We have a branch campus that needs to pull in program information from another site (graduate studies). The branch campus editors should not be able to edit the content being brought in since they are not the content experts on the subject. Graduate studies maintains the “master” content, then needs to be periodically pulled into the branch campus site. Then, using views we can display a list of content that we pulled in.


Being a semi-Drupal-newbie, this took quite a bit of trial and error before I figured out something that will work. If you know of another solution to this, by all means leave a comment! I’d love to hear it.

First thing I did was set up the RESTful module on the graduate studies site. This module makes it very easy to be able to expose our graduate program data as a read-only REST endpoint. I experimented with exporting it as RSS, or trying to build something to export the graduate programs as CSV or some other form of structured data but ended up going with JSON via the REST module. JSON is so widely supported, readable, and consumable by so many other applications that it seemed like it was the best route to go.

I’m currently working on a post about setting up the RESTful module! Sign up for email updates to get notified.

The feeds module alone doesn’t consume JSON, but luckily there is a really nice module called Feeds Extensible Parsers.

I’m also working on a post about setting up the Feeds Extensible Parsers module to read JSON!

I currently have it set up to update the branch campus’ program content every 3 hours. Using Drupal’s role and permissions, I can configure it so the branch campus editors can only read the program content, keeping it in sync with the “master” copy.
