XDIME is an xHTML Device Independent Markup Extensions. The acronym originally stood for XHTML with Device Independent Markup Extensions. It is a device independent authoring language. It allows content to be created once but delivered to the myriad traditional and mobile devices that can connect to the Web. Device-specific characteristics of a web site are captured separately as a set of policies that tailor the user experience to the particular type of device being used. Page layout, styling and media, such as images, are examples of resources that are controlled by policies. Style-related policies make use of the W3C CSS 2 specification. When a device accesses a site authored using XDIME, the markup and the related policies are subjected to Content Adaptation. This creates device-specific materials from the authored content and policies. The device-specific materials are appropriate for the particular device being used to access a site. XDIME has been in existence since the year 2000. Early in its life it was known as MAML and Marlin before finally gaining the name XDIME. Originally devised by Volantis Systems, the language has appeared in a number of products and services including Volantis' Multi Channel Server (MCS), and IBM's Mobile Portal Accelerator. It is at the heart of dozens of mobile networks across the globe. The latest version, XDIME 2, is based on the W3C Device Independent Authoring Language (DIAL) specification. DIAL itself includes some of the latest W3C specifications, including XHTML 2. XDIME-CP is a version of XDIME 2 that is particularly appropriate for content partners providing materials for an operator portal. This version allows the operator to retain some level of control over the look and feel of their portal while simplifying the task of integration. The original version of XDIME, now known as XDIME 1, is based on XHTML 1.1 and a very early draft of the XForms specification, also from W3C. Any version of XDIME can be used with a wide range of server-side technologies when creating applications. Ruby/Rails, PHP, Python, Perl and any of the Java web application technologies can be used.

Xdime
Xdime is a 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 Xdime rather than just read about it. In short: XDIME is an xHTML Device Independent Markup Extensions. The acronym originally stood for XHTML with Device Independent Markup Extensions.
Key takeaways
- Xdime belongs to science; place it in that map before memorising details.
- Learn the definition first, then one example that makes the definition concrete.
- Connect Xdime to a quantity you can measure, compute or draw — that is where exam questions come from.
- Reproduce the core statement of Xdime from memory before moving on to harder problems.
Reference excerpt
Worked examples
Example 1 — a first encounter with Xdime
Start with the simplest possible case. Write down what Xdime claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 Xdime 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 Xdime 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 Xdime
- In research
- Xdime appears in 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 Xdime 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
- Xdime is common in secondary-school and first-year university syllabi. It links to neighbouring topics Markup languages, so understanding it makes those chapters shorter.
- In everyday life
- Look for Xdime 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.

Frequently asked questions
What is Xdime in simple terms?
XDIME is an xHTML Device Independent Markup Extensions. The acronym originally stood for XHTML with Device Independent Markup Extensions.
Why does Xdime matter?
Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.
How should I study Xdime?
Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
What does this page cover?
It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on Xdime.
