THE WHOLE PICTURE
3
Introduction

• The general idea of the Resource Management
  system is to enable sharing of many different
  resources between as many users as possible.
• The idea of the resource is not limited to some
  laboratory equipment. It can be some software
  application or some interface to data stored in a
  remote database for example.

Principles

• object-oriented approach
• the object communication is standardized
• stationary agents as entities that work on
  different tasks in the system
• all communication protocols within Resource
  Manager are defined using XML

Experimental Results

• We involved end users (students) in functionality
  testing and used feedback from them to add all
  requested functionality
• We involved 38 users from Macedonia and Italy in
  the usability and education efficiency analysis.
• In general, users are satisfied with the RM
  usability

Conclusion

• We extended the concept of distance education
  with adding a new service, that we call Resource
  Manager
• By combining object-oriented design and
  definitions of common interfaces for the
  different types of agents for different types of
  resources, we designed extensible system, in
  which resources are added in an easy way.
