A set of open standards have been developed to support interoperability across Office 2.0 applications for document sharing, single sign-on, and linking/embedding of live office content in a web context. This set of standards is called "Open Simple Ajax Mashup" - OpenSAM for short - with a community web site at www.opensam.org. The OpenSAM standard builds on existing open Internet standards such as webDAV, CGI, AJAX, ALE (Ajax Linking/Embedding), and SSO (via HTTP authentication, OpenID, etc.).
This standards effort is intended to (1) make it easy for end-users to share documents across Office 2.0 applications from different vendors (2) easily access multiple Office 2.0 applications with a single login; and (3) embed a live spreadsheet in a document for example where each app comes from a different vendor.
The first commercial product built on the OpenSAM standard, ShareOffice, is comprised of five different web services (EditGrid, iNetWord, Preezo, ShareMethods, and salesforce.com) and this mash-up has just launched as the first online office in the salesforce.com AppExchange. It is hoped that the OpenSAM standards will lead to greater interoperability and choice for end-users when they seek to mash-up applications that they need for best of breed online office services.
