1. TT-eWIS/2018: Technology and Architecture (#5)
Jeremy Tandy (Chair)

2. Session aims:
Agree on what the big technological changes in WIS 2.0 are (the agenda includes a proposed list - but we can amend as we see fit),
Decide which of those elements will require changes to Technical Regulation / WIS Tech Specs (e.g. use of Internet, real-time messaging) and those that can evolve as recommended practices for inclusion in the Guide (the implication is that only Tech Regs are required changes- the rest can happen when/if Members are ready to implement and only then because they see benefit in doing so), and
Take an in-depth look at those elements that we think will require changes to Tech Regs (because these are the changes that will result in changes to systems with associated financial/resource implications).

3. Key questions to consider:
Where is controlled change required and where can change emerge?
What level of detail can we include in the WIS 2.0 Implementation Plan?

4. Candidate topics for discussion:
Decentralized / federated architecture
Telecommunications networks
Real-time messaging
Web services
Cloud
WIS Catalogue
Search engine integration
Data supply chains (distributed data policy enforcement)
