If you can remember when Markup Language was all we had to build a static web pages , you're old. Being old in the technology world is different than in the regular world; HTML came out in the early 1990s. HTML came from Standard Markup Language (SGML), which came from the Generalized Markup Language (GML). We still use HTML, so it's certainly not dead and gone; the industry has just promote upon the markup languages available to use.

A markup language is a way to structure text and how it'll be viewed. When you adjust alignment and other formatting capability in a word processor, you are marking up the text in the word processormarkup language. If you develop a web page , you are using some sortof markup language. You can handle how it looks and some of the actual functionality the page provides.

A more advantagious markup language , Extensible Markup Language (XML), was developed as a specification to create various markup languages (that is, extensible). An automobile organization will need to work with data as in pricing , parts, paint color, model, and so on. Let's see difference this to a organization that creates automobile part . This

industry will need to work with data elements will need to work with data elements as in production steps, inventory, synthetic rubber types, shipping steps to automobile companies, and such. If an automobile organization has a markup language tag of that is defined as a car model and the tire organization uses the same tag, , but its definition is of tire models-then there is a communication, or interoperability issue. Since the automobile industryneeds to tell the tire organization the type of tires it needs for itsinventory, if the organization uses the markup tag of , the automobile companieswould be sending the word "Mustang" when it needs to send a model number that represents a tire type.

So for the automobile and tire industryto be able to communicate, they need to say the same language. it is means that their applications need to both use and understand Extensible Markup Language . But each company has different types of data that they need to work with, so each uses a derivate standard of Extensible Markup Languages that best fits their needs.

Very interesting, but what does this have to do with access control? There has been a markup language that is built on the XML framework that shares information on what users should get access to what resources and services. So let ussay that the automobile industry and tire industryonly allow inventory managers within the automobile organization to order tires. The tire organization uses this identity information to make an authorization decision that then allows Bob's request for fourtytires to be filled.

The markup language that can support this type of functionality is the Service Provisioning Markup Language (SPML). This language allows organization interfaces to pass service requests , and the receiving company provisions (allows) access to these services. Since both the sending and receiving organizations are following one standard extensible markup language , this type of interoperability can occures.
