On HTML5's extensibility: how does microdata work in HTML5?
2009 Oct 30, 10:33
"What does a Uniform Resource Identifier (URI) mean? Does it have a sense, and can it refer to things?" I hope it will cover some of the new scheme vs always HTTP scheme and distinct vs not distinct
URLs for a real world object and its web page perma-arguments.

"Each unit has a stable URI, making it possible to link to it from your own domain models in a reliable way. For each unit, the ontology defines some useful metadata including abbreviation, a link to
DBpedia and a categorization of units into groups, such as length units."

A sort of vertical cross section of an overview of what the web should look like from HTTP & URIs to GRDDL & RDF. Oh, and there's a pretty graph at the bottom. "This finding describes how document
formats, markup conventions, attribute values, and other data formats can be designed to facilitate the deployment of self-describing, Web-grounded Web content."

I've made another extension for IE8,
Outline View, which gives you a side bar in IE that displays an outline of the current page and lets you make intrapage bookmarks.
The outline is generated based on the heading tags in the document (e.g. h1, h2, etc), kind of like what W3C's Semantic data extractor
tool displays for an outline. So if the page doesn't use heading tags the way the HTML spec intended or just sticks img tags in them, then the outline doesn't look so hot. On a page that does
use headings as intended though it looks really good. For instance a section from the HTML 4 spec shows up quite nicely and I find its
actually useful to be able to jump around to the different sections. Actually, I've been surprised going to various blogs how well the outline view is actually working -- I thought a lot more
webdevs would be abusing their heading tags.
I've also added intrapage bookmarks. When you make a text selection and clear it, that selected text is added as a temporary intrapage bookmark which shows up in the correct place in the outline.
You can navigate to the bookmark or right click to make it permanent. Right now I'm storing the permanent intrapage bookmarks in IE8's new per-domain DOM storage because I wanted to avoid writing
code to synchronize a cross process store of bookmarks, it allowed me to play with the DOM storage a bit, and the bookmarks will get cleared appropriately when the user clears their history via the

Lots of neat web APIs. Added to Delicious network. "Over the past year, I've been tagging interesting data I find on the web in del.icio.us. I wrote a quick python script to pull the relevant links
from my del.icio.us export and list them at the bottom of this post. Most of these datasets are related to machine learning, but there are a lot of government, finance, and search datasets as well."

"This is an experimental service that makes the Library of Congress Subject Headings available as linked-data using the SKOS vocabulary. The goal of lcsh.info is to encourage experimentation and use
of LCSH on the web with the hopes of informing a similar effort at the Library of Congress to make a continually updated version available. More information about the Linked Data effort can be found
on the W3C Wiki."

Interview with Ben Adida on RDFa: "...RDFa is ready. It has just been approved by the W3C as a Candidate Recommendation, with the specific text of the specification and a brand new Primer published
on June 20th. Y!: What can I do with RDFa? BA: You can tell the world what various components on your web page mean by marking up things like: The title of a photo Your name and contact information
The license under which you're distributing your latest MP3 The ingredients of a cooking recipe The price of an item A gene on which you recently wrote a paper ... Anything that you want to make more
