Metadata

Metadata is data about data

Where you have content, including grapics, illustrations, flash movies, text, you can also have descriptions of attributes of that content. This page has content, of which this paragraph is one part. The metadata for this content includes its page title (“MetaData“), the date of last modification, the size of the page, the category the content is classified into, etc.

Metadata falls into five categories: administrative, descriptive, prescriptive, technical and use. It is descriptive metadata that we most often use in controlled vocabulary creation efforts. So once the descriptive metadata is harvested through indexing efforts, the classification can begin.

For non-metadata-ites here are some notes TomWorthington? did for e-commerce students at The Australian National University:


JoDI, the Journal of Digital Information, has a new issue out dedicated to the topic of MetaData.

The UK Government’s Office of the e-Envoy has released their e-GovernmentMetadata? Set for comment:

This metadata set, based closely upon the Dublin Core, is intended to meet the needs of e-Government in the UK, but is already attracting significant interest overseas.

It mentions AGLS (Australian Government Locator Service), but is more akin to the Recordkeeping Metadata Standard for Commonwealth Agencies (RKMS?). RKMS? extends AGLSfor record keeping purposes with items such as “Disposal” (also in the UK standard):

MappaMundi? has an excellent and [meaty introduction to MetaData]


http://bitzi.com/about/intro – a kind of distributed metatagging effort for all types of files – seems focussed on adding metadata to P2P filesharing.

Label Design

“Labels are the words and phrases throughout your site that identify content. Employing a labeling scheme and applying effective, coherent labels can make the difference between a site that’s a pleasure to navigate and one that doesn’t get bookmarked because it’s too much trouble to use. “
