element

Semantics?What does “og:description” mean?

And how would my browser know?

What does it relate to?

A first step:

Microdata<div id="watch7-container" class="transition-content" itemscope="" itemid="" itemtype="http://schema.org/VideoObject"> <link itemprop="url" href="http://www.youtube.com/watch?v=6qsH_LFRr6k"/> <meta itemprop="name" content="Despicable Me 2 - Teaser (HD)"/> <meta itemprop="description" content="http://despicable.me"/> <meta itemprop="duration" content="PT0M54S"/> <meta itemprop="unlisted" content="False"/> <meta itemprop="paid" content="False"/> <span itemprop="author" itemscope="" itemtype="http://schema.org/Person"> <link itemprop="url" href="http://www.youtube.com/user/DespicableMeMovie"/> </span> <link itemprop="thumbnailUrl" href="http://i3.ytimg.com/vi/6qsH_LFRr6k/hqdefault.jpg"/> <span itemprop="thumbnail" itemscope="" itemtype="http://schema.org/ImageObject"> <link itemprop="url" href="http://i3.ytimg.com/vi/6qsH_LFRr6k/maxresdefault.jpg"/> <meta itemprop="width" content="1280"/> <meta itemprop="height" content="720"/> </span> <link itemprop="embedURL" href="http://www.youtube.com/v/6qsH_LFRr6k?autohide=1&version=3"/> <meta itemprop="playerType" content="Flash"/> <meta itemprop="width" content="1280"/> <meta itemprop="height" content="720"/> <meta itemprop="isFamilyFriendly" content="True"/> <meta itemprop="regionsAllowed" content="AD,AE,AF,AG,AI,...,ZA,ZM,ZW"/></div>

METADATA

We’re stuck with

this...

HYPERDATA...until we manage to make the

metadata machine-comprehensibleand inter-linked.

Metadata’s Main Building Blocks:

Data Models

Classification Schemes

Data Modelstitle

authordirector

descriptionimage

actor

synopsis

genre

Data models tend to be:static well structured documented

The Easy PartXier

somewhatmore or less


Are basically lists of stuff

CS-es tend to be:dynamic poorly structured undocumented

The Tough Part


The worst case:

Inline Classifications

<xs:simpleType name="GenreType"> <xs:restriction base="xs:string"> <xs:enumeration value="Action"/> <xs:enumeration value="Drama"/> <xs:enumeration value="Romance"/> </xs:restriction></xs:simpleType> Bad!


Legacy!
