Introduction

• What is FREMA?
• JISC funded Project between Southampton,
  Strathclyde and Hull
• Part of the e-Learning Framework (ELF) effort
• What is the ELF?
• Service Oriented Architecture for e-learning
  systems
• Layered (Domain services over Common Services)
• Dynamic and evolving
• What is a Reference Model?
• A description of how services behave within a
  particular domain
• A community resource

What is a Reference Model?

• Domain Definition
• Overview of the domain, and how projects and
  standards fit within it

• Identifying Common Usage Patterns
• Scoping the FREMA Project

• Developing Use Cases
• Formal descriptions of usage patterns

• Gap Analysis
• Mapping of Use Cases to the Services in ELF

Reference Impl

• Service Profiles
• Formal descriptions of those services

Service Profiles

• Reference Implementation
• Of key/core services
• Examples
• Validation
• Resource

Assessment Domain Definition

What does it look like?

• An evolving, cross-referenced, searchable web
  site
• Indexed resources and narrative descriptions of
  the domain
• UML Use Cases and Scenario documents
• Service descriptions, narrative and WSDL
• Service implementations to download (Java/.NET)
• Different gateways into the model
• according to how you want to use it

How might you use it?

• Use the Reference Implementation
• Build on some or all of the developed services
• Use the Service Profiles
• To develop your own services that will fit into
  the framework
• Use the Use Cases
• To help understand usage patterns within the
  domain
• Develop new Service Profiles and thus Services
• Use the Domain Definition
• To develop a context for your own work
• Understand how existing work fits together
• Identify standards
• Locate experts

Road Map to a Reference Model

• Incremental
• Evolutionary
• Agile
• Community Open Source
• Components
• Using existing open source infrastructures and
  web services, e.g.
• Web servers, authentication services
