The most common definition of the term 'metadata' is data about data -- information that describes other information. For example, this web page has an author, a title, a date of creation, and a unique Internet address; this information constitutes the metadata about this page.
Metadata is the key to providing services like ADAM; our Resource Officers are creating a searchable catalogue of metadata records that describe quality-assured resources in art, design, architecture & media on the Internet.
We are also keen to promote the use of metadata by resource authors; often the best person to describe a resource is the person who created it! By using simple techniques such as the Dublin Core to embed metadata in web pages, authors help services like ADAM to quickly and accurately describe the resources, and thereby help end users to find the information they really need.
This page contains some descriptive metadata, invisibly embedded in the HTML using the <META> tag in the <HEAD> section; it looks something like this:<META NAME=DC.Creator CONTENT="Tony Gill">
<META NAME=DC.Title CONTENT="ADAM Quick Guide to Metadata">
<META NAME=DC.Subject CONTENT="ADAM, Dublin Core, internet cataloguing, metadata">

General Metadata Resources
A review of metadata:
a survey of current resource description formats
Arts, Museums & Cultural Heritage Information Standards
The Dublin Core is a simple set of 15 descriptive elements that can be used to describe network resources such as web pages. It is particularly useful for web page authors, because:
There are now a number of useful Dublin Core resources available over the Internet; this selection represents a domain-specific (and personal) selection of some of the most useful:
Dublin Core Metadata Iniative
Arts, Museums & Cultural Heritage Metadata Workshop Report
Discovering Online Resources Across the Humanities: A Practical Application of the Dublin Core
Down Under with the Dublin Core
The Dublin Core 'apple core' logotype (originally produced as a joke for Tony Gill's personal web pages!), has now spread to a number of more serious sites, for example the Nordic Metadata Project.
In the light of popular demand, the logo has been cleaned up, given a web-safe 16-colour palette with a transparent background, and made available in a range of sizes; please feel free to download and reuse any of the following images from this page.
The logo below is the 'original' 1996 version.
