The capability allows third party developers to use Google Drive’s collaboration feature on their respective applications.
“Developing for the Drive Realtime API is almost as simple as working with local objects. The API provides collaborative versions of familiar data objects such as maps, lists, strings, and JSON values and automatically synchronizes and stores modifications to these objects. Your application reads from and writes to these objects like any other local object. Change event handlers can be added to collaborative objects so that your app can react to changes from other collaborators,” explained Google Software Engineer Brian Cairns in a press release.
Google Drive launched in April of last year and provides users with 5GB of shared storage.
