Australian Government Locator Service (AGLS) metadata standard

The Australian Government Locator Service (AGLS) metadata standard is a set of 19 descriptive elements to improve the visibility and accessibility of services and information over the Internet (NAA 2000a). The AGLS standard is based upon the Dublin Core international online resource discovery metadata standard (OCLC 2000).

www.fed.gov.au, the Commonwealth Government Entry Point, offers comprehensive and integrated access to Federal Government information.

You will find a concentrated body of Australian Commonwealth Government information through this site. www.fed.gov.au currently signposts over 500 Federal Government web sites, indexes more than 1,000,000 pages and uses both metadata and free text indexing to ensure it is a comprehensive government portal...

The site runs on a Sparc E450 Unix server and uses the CiTR AccessPoint software suite. It is constantly updated through harvesting in accordance with our Information Governance Policy.

The topic trees are maintained by Department Of Communications, Information Technology and the Arts staff ...

The site provides an advanced search for specific metadata values.

Reg

The Distributed Systems Technology Centre (DSTC Pty Ltd), has produced a metadata tool to create AGLS and Dublin Core metadata. Reg, can be used to automatically generate AGLS metadata using an approved form of syntax. This is also a useful way to learn about the syntax.

... Reg allows you to:

Reg uses metadata schemas to customize itself for different metadata element sets. Some samples are provided below, or you can write your own by following the schema documentation and using the example schemas as a guide.

Reg can extract metadata from HTML documents (as is done for the Commonwealth Government Entry Point):
