Mozilla Labs as always makes us happy with new innovative ideas.
Maybe you remember post of Vasiliy Kiryanov about Mozilla Prism: with that platform we can use web-applications like regular desktop applications [http://blogs.helion-prime.com/vasiliykiryanov/2008/06/03/new-web-experience-with-mozilla-prism.html]
And now new fresh idea from Mozilla Labs: Ubiquity as a way “connecting the Web with language”.

Ubiquity way

For a long time people have idea to create a way to store and query data of any application easy.
It can give enormous flexibly like everything is already here and in appropriate format. We know this idea as W3C Semantic Web[http://ru.wikipedia.org/wiki/Semantic_Web], as we are still far from it, software developers on Internet are using mashups [http://en.wikipedia.org/wiki/Mashup_(web_application_hybrid)] to get similar effect today.

But what can we do from user side when we want to connect many different applications together, and use them in a same way. Ubiquity propose a way to describe common tasks in the Web using language-based instructions, and then you can create you own mashups with help of existing open Web APIs.

To have a better understanding how it work you can watch following video:
