Interoperability - a wider view

• Interoperability isn’t just metadata, APIs and wire protocols

• It’s policies, comparability and markets

• People want to compare services

• We need trust in transferability

An external perspective

• None of us are perfect

• Without oversight, standards can slip

• External perspectives encourage improvement

• Audit formalises this

But what about interoperability?

• Easier to please auditors when using standards

• Easier to compare A with B

• Audits themselves - in standard form - allow consumers, depositors to compare

• Is A better value/more trustworthy/more secure/more open than B?

An trivial example

• What is the likelihood that you will lose 1 bit in X years ?

• What confidence limits apply to that number ?

15

Not so trivial

• What is the energy cost of preserving X bits over Y years ?

• Do you do an environmental audit ?

• Are you certified against recognised standards ?

Interoperable policies

• I give you content - we have an agreement

• Content is later transferred - merger, takeover, change of collection policy

• Is my agreement transferred ?

• Who do I sue ?

How does it help

• Contracts, service level agreements, performance measures

• Comparability is desirable

• Interoperability - of a form - follows

• Customers don’t like lock-in

• Intelligent ones design it out - exit plans
