Semantic is a set of specifications for sharing UI elements between developers. Semantic is also a UI library to make front end development simpler and easier to learn.
For developers, this means defining class names for UI elements, outlining states that an elements can exist, and describing common variations of that element.

## A More Semantic Web
### Based on class
Semantic is based on class names, instead of tags. This means, except for links, tables and forms, you can use semantic with tags like ``<div><article><nav>`` without any difference.
In Semantic, variations maintain context based on the element they modify, but keep the same vocabulary between elements. Just like how in English, the adjective 'big' may describe a different scale for a big planet versus a big insect.
UI Elements are interface elements which do not contain other elements inside themselves. This can be thought of as similar in definition as an "element" in chemistry.
UI Collections are groups of heteregeneous UI elements which are usually found together. Carrying the chemistry metaphor, these can be thought of as molecules.
UI collections have a definition of elements that exist, or could exist inside of them. They do not usually require all elements to be found, but they describe a list of the "usual suspects". Unlike elements, collections are not typically useful to define in plural.
UI modules are elements where it's behavior is a fundamental part of its definition. UI Modules are dependent on the javascript which carry their definition. They also may be more complex, and have a variety of different functions. Further abusing the scientific analogy: These can be thought of as "organs".
UI Views are common ways to structure types of content so that it can be understood more easily. A view's definition in semantic only describes the content which typically occupies the view.
Semantic is very new standard, and we need a community to become truly useful. We're working currently to determine the best ways to engage the community for contribution. If you'd like to participate feel free to reach out by e-mail [semantic@quirky.com](mailto:semantic@quirky.com)
