Microsoft Assistance Markup Language

Microsoft Assistance Markup Language is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Microsoft Assistance Markup Language rather than just read about it. In short: Microsoft Assistance Markup Language (Microsoft AML, MAML) is an XML-based markup language developed by the Microsoft User Assistance Platform team to provide user assistance ("online help") for the Microsoft Windows Vista operating system. It makes up the Assistance Platform on Windows Vista.

Key takeaways

Microsoft Assistance Markup Language belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Microsoft Assistance Markup Language to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Microsoft Assistance Markup Language from memory before moving on to harder problems.

Reference excerpt

Microsoft Assistance Markup Language (Microsoft AML, MAML) is an XML-based markup language developed by the Microsoft User Assistance Platform team to provide user assistance ("online help") for the Microsoft Windows Vista operating system. It makes up the Assistance Platform on Windows Vista. MAML is also used to provide help information for PowerShell V2 Cmdlets, modules and advanced functions.

Concept MAML is a departure from all previous types of user assistance for Windows operating systems. Some of its features have been available in .NET Framework 2, but more options shipped with the release of .NET Framework 3. Previously, user assistance for Windows operating systems used Microsoft Compiled HTML Help files, which contain little machine-readable semantic information. The most significant aspect of MAML is that it shifts the production of user assistance to the concept of structured authoring (somewhat similar to DITA or DocBook). Documents and their constituent elements are defined by their context. With MAML, the emphasis is on content and the tasks a user performs with a computer, not the features of the software. Presentation is managed as part of the rendering engine when a user requests a topic. The structured feature of MAML means that it can express a wide range of active concepts as well. One notable feature is guided help (active content wizard), which allows the help file to either run a task automatically or highlight the parts of the screen a user should interact with step-by-step. The feature was a notable aspect of Project Longhorn, yet Microsoft opted not to incorporate it into the ultimate release of Vista. The MAML authoring structure is divided into segments related to a type of content: conceptual, FAQ, glossary, procedure, reference, reusable content, task, troubleshooting, and tutorial.

Presentation Three levels of transformation occur when a topic is displayed: structure, presentation, and rendering:

The structural transformation contains reusable content and applies conditional logic to determine the structure that content should take when it is displayed, and the content of the text itself. The presentation transformation enables content authored in MAML to be used in many different formats, including DHTML, XAML, RTF, and printed material. The rendering transformation applies style sheets and displays the final content to users.

Authoring PlatyPS can be used to create MAML contents for PowerShell Help using the markdown format. An application such as Notepad, Notepad++, or Infopath may be used to manually create MAML content.

Format MAML content uses the h1s help file format, which, along with the HelpPane viewer, is found in Windows Vista and Windows 7. The format is similar to Microsoft Help 2 .hxs files. A third party "xHelpMarkup" tool for compiling and decompiling exists, but it is only a wrapper around the BDD 2007 apcompnt and apss.dll tools.

Worked examples

Example 1 — a first encounter with Microsoft Assistance Markup Language

Start with the simplest possible case. Write down what Microsoft Assistance Markup Language claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Microsoft Assistance Markup Language before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Microsoft Assistance Markup Language ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Microsoft Assistance Markup Language

In research: Microsoft Assistance Markup Language appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Microsoft Assistance Markup Language in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Microsoft Assistance Markup Language is common in secondary-school and first-year university syllabi. It links to neighbouring topics Markup languages, Microsoft application programming interfaces, Software help, so understanding it makes those chapters shorter.
In everyday life: Look for Microsoft Assistance Markup Language outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
