Novell Vibe
Novell Vibe is a web-based team collaboration platform developed by Novell, and was initially released by Novell in June 2008 under the name of Novell Teaming. Novell Vibe is a collaboration platform that can serve as a knowledge repository, document management system, project collaboration hub, process automation machine, corporate intranet or extranet. Users can upload, manage, comment on, and edit content in a secure manner. Supported content includes documents, calendars, discussion forums, wikis, blogs, tasks, and more.

Document management functionality allows for document versions, approvals, and document life cycle tracking. Users can download and modify pre-built custom web pages and workflows free of charge from the Vibe Resource Library.

History
Novell Vibe is the result of a merging of two products in November 2010: Novell Teaming and Novell Pulse.

Novell Teaming began as SiteScape Forum. When Novell Acquired SiteScape in 2008, the name was changed to Novell Teaming.

Created in 2009, Novell Pulse was a communication tool based on the Google Wave Federation Protocol.

Server
Any combination of Linux and Windows servers can run the Vibe application. Furthermore, MySQL, MS SQL, and Oracle databases are supported.

End-User operating systems
Windows, Linux, Mac, iOS or Android

Browsers
Firefox, Internet Explorer, Safari, or Chrome

Mobile
Any mobile device that has a browser can access the Vibe site. Native iOS and Android apps are available for free download in the app stores.

Microsoft Office integration
Word, PowerPoint, and Excel (versions 2013,2010 and 2007) on the Windows operating system are supported.

Interoperability
Vibe can be used in conjunction with various other software products, such as Novell Access Manager, Novell GroupWise, Skype, and YouTube. Novell Vibe integrates with an LDAP directory for authentication.

Extendability
Vibe administrators can extend the Vibe software by creating software extensions, remote applications, or JAR (file format) files that enhance the power and usefulness of the Vibe software to create a custom experience for users.

Software extensions enable third-party developers to create abilities which extend an application. Vibe administrators or Vibe developers can create custom extensions (add-ons) to enhance Vibe. For example, you might have an extension that enables Flash video support in Vibe.

Remote applications
A remote application is a program that runs on a remote server and delivers data for use on the Novell Vibe site (such as data from a remote database). For example, Vibe administrators or Vibe developers could set up a remote application for Twitter that displays all of a user's Twitter entries in Vibe.

Unlike creating an extension for Vibe, creating a remote application does not modify the Vibe software.
