Google introducing the "Google Apps extensions console," a new tool to help IT departments and in-house applications developers integrate with Google Apps.
"In-house developers can now access the same Google Apps extension points first introduced in the Google Apps Marketplace. Applications can create links in the navigation bar (alongside "Calendar" and "Documents"), share a single sign-on with Google accounts, and run inside Gmail using rich contextual gadgets," Google stated.
"The extensions console helps in-house developers create new projects, manage team permissions, retrieve OAuth credentials, and upload their application manifest. Once the app is ready to deploy, administrators can install the app to their domain control panel for wider release."
Also, with Gmail contextual gadgets, Google released a set of predefined extractors that developers could use. "These extractors allow developers to match content within a single part of an email message, such as the subject, and use that content to display relevant information to the current user."
"These complex patterns, known as custom extractors, are now available to drive contextual gadgets," announced Google.
"Custom extractors allow developers to trigger their gadget when a series of conditions are met. For e.g., a developer could write an extractor that triggered a gadget only when "Hello world" appeared in the subject and "firstname.lastname@example.org" was the sender of the email. This allows developers to more finely tune their gadgets, and provide even more relevant contextual information," explained Google.
