There are various projects which already use Okapi.
- local.ch uses Okapi for all frontend aspects. Internally a service-oriented architecture is used, where backend services execute searches, provide data from various sources and also handle persistency where needed. The frontend communicates with the backend over a REST XML interface. Okapi's models are used to communicate with those services, while the XSLT views are perfect for styling the XML responses.
- EPG DRS
- The Electronic Program Guide (EPG) of the Swiss public radio DRS is a business critical back office application to manage all the aspects of the program for the multiple channels of Radio DRS. Okapi is used for the whole application - for delivering the administration frontend GUI to the editors within the radio and providing the needed data via a REST-Style API to the public web page. JSON, XML, XSLT and YUI are important parts of this application, as well.
- The E-Learning project iconomix - an initiative by the Swiss National Bank - uses Okapi to deliver the content of the pages and to communicate with the Open Source E-Learning Platform Moodle in the backend. The site is accessible, follows a lot of standards, is easily scalable and uses a smart session handling with the backend, thanks to the underlying XML/XSLT and Okapi technology.
- Best of Swiss Web
