Dev.Opera — Microdata & the microdata DOM API
IntroductionOne of the main problems HTML5 set out to solve was consistency (and therefore machine-readability) of markup, evidenced by the introduction of standard semantic elements such as <header>, <nav> and <figure>. This is all well and good, but there are times when you’ll want to add specific machine-readable data attributes to pieces of content so that they can be read consistently by some
Microdata, the Web Component Model and hybi-17 for Web Sockets « Peter Beverloo

Microdata + schema.org を実際に使ってみる
schema.org は Google、Microsoft (Bing)、Yahoo! という Web 検索の大手 3 社が共同で取り組んでいる試みで、より構造化されたマークアップのための共有の語彙集 (vocabulary) を提供しようというものです。この schema.org の語彙を利用して、実際のマークアップに Microdata を追加する具体例をいくつか考えてみました。 schema.org の アイテム型 (item type) は 階層 (hierarchy) のかたちで定義されています。型ごとに独自の プロパティ が定義され、上位の型のプロパティは下位の型に引き継がれます。最上位は Thing という汎用の型で、name、url、image、description というもっとも基本的なプロパティが定義されています。そしてその下に CreativeWork、Event、
An Uber-comparison of RDFa, Microdata and Microformats | The Beautiful, Tormented Machine
Relative Complexity Relative Complexity is a fuzzy measure of how difficult it is to achieve mastery of a particular structured data syntax. Microformats is by far the easiest to pick up and use. Microdata is a big step up and a bit more complex. RDFa is the most complex to master. There are design trade-offs, the simpler the syntax, the fewer structured data markup scenarios are supported. The mo
Schema.org and Pre-Existing Communities
I have been reading tweets and blog posts expressing various levels of disappointment and unhappiness about schema.org not using RDFa, not using Microformats or not having been developed in the open with the community. Since other people’s perspectives differ from mine, I feel compelled to write down my take. Disclaimer: I’m only speaking for myself on my own time and initiative. Expect blatant bi
Microdata - Dive Into HTML5
Microdata annotates the DOM with scoped name/value pairs from custom vocabularies. Now what does that mean? Let’s start from the end and work backwards. Microdata centers around custom vocabularies. Think of “the set of all HTML5 elements” as one vocabulary. This vocabulary includes elements to represent a section or an article, but it doesn’t include elements to represent a person or an event. If
【レポート】HTML5新機能、Microdataとは | エンタープライズ | マイコミジャーナル
Ext JS is now Sencha HTML5の策定とともに進められている機能に「Microdata」がある。2009年末ごろにHTML5本体から分離し、今はHTML5関連技術として5 Microdata - HTML 5にそのドラフトが公開されている。MicrodataはHTMLコンテンツに特定のメタデータを追加するためのもの。類似の技術にはMicroformatsやRDFaなどがある。 Microdataは名前と値をひとつの組みとする。Microdataでは名前と値の組みをアイテムと読んでいる。5 Microdata - HTML 5に掲載されているサンプルによれば、次のように記述する。 <div itemscope> <p>My name is <span itemprop="name">Elizabeth</span>.</p> </div> itemscope属性でアイテム
Getting Started - schema.org
Note: you are viewing the development version of Schema.org. See How we work for more details. Getting started with schema.org using Microdata Most webmasters are familiar with HTML tags on their pages. Usually, HTML tags tell the browser how to display the information included in the tag. For example, <h1>Avatar</h1> tells the browser to display the text string "Avatar" in a heading 1 format. How
Schema.org - Schema.org
Note: you are viewing the development version of Schema.org. See How we work for more details. Full Hierarchy Schema.org is defined as two hierarchies: one for textual property values, and one for the things that they describe. This is the main schema.org hierarchy: a collection of types (or "classes"), each of which has one or more parent types. Although a type may have more than one super-type,
