Microsearch debuted at ETech today

Decentralization, Event Driven Architectures, Semantic Web By: ams

We showed off a re-skinned version of our Ångströ project at in San Diego that I hope makes a bit more sense as microsearchyou know, for . 🙂

We pointed at a live instance at http://tpd.angstro.net:19988/ — go search, grab the miffy bookmarkley, and start adding microformats to our big shared pile of bits!

Congratulations for an applause-winning demo to Ben Sittler, as the mad Javascript genius behind the whole system, and Elias Sinderson, who added semi-structured XQuery to the system!

Herewith, some notes from our slides…


What is “Atomic-Scale”?

Web pages contain chunks of information

A natural consequence of growing adoption of template languages & content management tools

Feeds create the illusion of immediacy

As chunks of information change, we can expect notification (in the form of updated feed files)

Microformats create the illusion of structure

Even if it’s HTML all the way down, we can read it

… so maybe REST will make more sense for atoms than for pages

How miffy works

walks through the document looking for the ‘root classes’ of the µfs it knows about

places green anchor boxes in front of them
using css — no graphics, since we want it to work offline

‘capturing’ clones those DOM nodes, then walks the tree to “reformulate” it

the only data structure that can represent all future µfs is the DOM itself

For More Information

Is Open Source —
but not yet an open-repository
