Improved ranking in search results is the major benefit of using metadata from the point of view of the web designer, more relevant search results are the benefits for the user. However, the concerns of many metadata initiatives, like the Dublin Core Initiative, are more wide-reaching. Their aim is to develop standards that will enable the indexing, cataloguing and preservation of digital information and resources.
In 1995 the Dublin Core Initiative began to develop standards for electronic resource discovery on the World Wide Web. These standards are deliberately kept simple and flexible, so that authors can provide metadata by themselves (Simplicity of creation and maintenance), that any Internet document can be described with it (Commonly understood semantics, Extensibility, Interoperability among collections and indexing systems) and that it can be easily adapted into other languages (International scope and applicability).
The metatags are placed within the HEAD section of the HTML code of a web page. The Dublin Core element names are preceded by 'DC'. All elements are optional.
The DC metadata for this document looks like this:
<TITLE>Metadata - Dublin Core</TITLE>
<META NAME="DC.Title" CONTENT="Metadata - Dublin Core">
<META NAME="DC.Creator.Address" CONTENT="email@example.com">
<META NAME="DC.Subject" CONTENT="metadata, metatags, Dublin Core, guidelines, web design, resources, HTML authoring">
