The aim of this tutorial is to get you familiar with Metadata and Electronic Document Management. You can attempt these in your assigned tut/lab time, or at a time convenient to you. You are encouraged to discuss the questions, and solutions to them, with your fellow students. Sample solutions, or leads to solutions, will be provided at a later date. You are also strongly encouraged to initiate discussions on the newsgroup teach.comp3410.talk if you get stuck. You can also send email to firstname.lastname@example.org. A reply will either be sent to you, or will be posted to the newsgroup (if the same question is asked by many students). Any feedback is always welcome.
You can use the Mozilla browser to view Metadata and XML material. You need to log on to challender for this to work. For both browsers, set the HTTP proxy (in manual mode) to wwwcache.anu.edu.au with the port number being 80.
Write a Dublin Core metadata description with HTML 4.0 Meta-tags for the for a document that stores the following information:
URL: http: //www.naa.gov.au/recordkeeping/gov_online/agls/summary.html
Creator: National Archives of Australia
Rights: Copyright © Commonwealth of Australia 2000
Title: Australian Government Locator Service (AGLS) introduction
Subject: information management; information retrieval; business records
Description: This page provides access to information about AGLS, including the AGLS manual and advice on implementing AGLS for Commonwealth agencies.
Use DSTC's Reg or Reggie metadata tools to create AGLS metadata for the above. Add at least one AGLS qualifier (such as a Scheme) to refine the semantics of the element set. Save the metadata in both HTML 4.0 and RDF formats.
Compare the metadata generated with that in the actual document URL: http: // www.naa.gov.au/recordkeeping/gov_online/agls/summary.html

What elements have been added to the AGLS metadata to form the Commonwealth recordkeeping metadata set? Why?
The front part of the thesis " THE PERSONAL COMPUTER AND THE PUBLIC LIBRARY: A STUDY OF THE ABSORPTION OF NEW TECHNOLOGY AND AN ANALYSIS OF LIBRARIAN'S OPINIONS ABOUT THE PRESENT AND FUTURE IMPACT ON AUSTRALIAN PUBLIC LIBRARIES" is 745.5 kbytes, which is large for a 13 page text-only document. Why is the document so large? What PDF options could be used to reduce the size and improve readability?
Run the Bobby or WAVE automated test tools to see if the Department of Computer Science home page conforms to standards. What changes are needed to comply with recommendations World Wide Web access, from the use of the Human Rights and Equal Opportunity Commission?
