The open API lets you integrate modules with the platform using your language of your choice… Java, ASP.Net or PHP. Because it’s open, you can integrate open source and 3rd-party web services from your favorite vendors without ever being locked into a single vendor. The API also empowers you to integrate with legacy apps and data sources. With all this – you’ll enjoy a single sign-on, common security model, federated search and other benefits of a proven platform.
