Although Weller applies this thinking to VLEs the same must apply to e-portfolios.

KEY ISSUES

• Exchange of learning resources
• Passing of data between institutions
• Multiple platforms
• Software applications that communicate with other students

'Agnostic’

Interoperability

The argument for standardisation is made in relation to electricity plugs.

• platform agnostic
• language agnostic
• IPR terms to share

Modularisation – like music through Napster and the commercially through iTunes.

Problems

• semantic
• modularisation
• security
• quality
• licensing
• development tools

Standards

Is interoperability in relation to the transferability of data and resources like issues of access for disabled people?

Transferability adds a dimension from a point moving forward, as well as going back, and weaving across.
