RepoMMan
• Workflow
• Automated metadata
• Surface in portal/C & LE (Sakai)
• Informed by user requirements analysis
Service Oriented Architecture
• Standards based
• Flexible
• Breaking down the monoliths– reuse and recombination
• Web Services
What are we doing?
• Generic workflow tool– flexible enough to provision research, learning
and admin
• Connect to Fedora functionality over WS
• Future reuse of the tool
• 3 tier architecture– Presentation - MVC - Orchestration
How are we doing it?
• Addressing the SOA challenge of orchestration
• Building on the success of a previous JISC project - Assis– coordinating 3 external learning services
• Using Business Process Execution Language from OASIS– Based on earlier specs from Microsoft and IBM
BPEL
• XML based workflow language
• Enables the orchestration of Web Services
• Synchronous and asynchronous processes
• Fault handling and rollback
• Loose coupling via aliases
User requirements
• Face to face interviews
• On-line survey (Hull University)
• On-line survey (international)
