WCM Decentralized Authoring
Overview
In most environments, a single Authoring application will be sufficient to manage all authoring activities. In some cases, though, a set of decentralized Authoring applications may be required.
E.g. - if you have users located in different locations it may be more efficient to install a local Authoring application at each location. Two-way syndication is used between all Authoring applications and the Staging application. This allows changes made at all remote locations to be visible to all users.
Authoring 1
Authoring 2
All Authoring applications syndicate to a Staging application.
The Staging application subscribes from all Authoring applications.
Staging Application
Decentralized Authoring creates the risk of conflicting updates between Authoring applications. This may be managed by using different Authoring applications for different Sites, or different sections of a Site. You could also use different Authoring applications for different user roles. E.g. - Content creators could use a different Authoring application than Presentation Template designers.
Access to each decentralized Authoring application is controlled using a combination of Authoring Portlet (Web Content Authoring) access controls and Item Security settings. E.g. - Only users requiring access to the local Authoring application would be granted access to the local Authoring Portlet (Web Content Authoring). Users would be given "Read" access to all Items , but only "Edit" access to Items they are required to update. See Access and Security for further information.
Syndication
Syndication is used as the transport layer that replicates data from one Web Content Management application to another.
Clusters
As it is essential that each user maintain a session with a single server, decentralized Authoring applications would not be deployed in a cluster.
Distributed Session Persistence
The WCM Authoring portlet and Local Rendering Portlet cannot be used in a clustered environment that has distributed session persistence enabled. To display WCM content in WebSphere Portal pages in a clustered environment that has distributed session persistence enabled use a Remote Rendering Portlet pointing to a WCM application located outside the clustered environment.
