Beginning with version 6.0.1, IBM WebSphere
® Portal uses Piece of Content (POC) URIs to identify and address specific pieces of content in IBM
Connections. Using a POC URI, you can precisely identify what content you want to display in a portlet. For example, when a user clicks a link in a blogs summary portlet, the POC URI identifies the blog content and displays it in the Blogs detail portlet. In earlier versions of Portal, this connection would be made using a standard URL to identify the target page of the content. URLs were limited and did not allow access to precise information about the state of a piece of content. The evolution to POC URIs provides a greater precision for identifying, retrieving, and displaying content. The URI specifies the identity of the content, not the location of the view of the document. The location of the view to the document is called the portal URL, or simply URL and the information contained in this URL is the navigational state, or simply state.
For detailed information on the creating and using custom URIs to access content, see the article Leveraging WebSphere Portal V6 programming model: Part 5. Accessing portal content with custom URLs
