Portal Markup Language (PML)

Portal Markup Language (PML), an application of the Extensible Markup Language (XML), describes the characteristics of a product that is used to create a portal Web site (sometimes referred to as an enterprise information portal). PML allows manufacturers to exchange information in a standard way about "information objects, users, groups, access control subscriptions and notifications managed by the system." PML is spelled out in a formal document tag definition (DTD). PML does not describe syndication (how content from one site could be published on other sites).
