*Discussion*

  • SOA WG update - Leo
    Survey responses are starting to come in, 4 completed to date.
    Follow-on interviews are being arranged. More info forthcoming as a available.
  • Pub/Sub Architecture Discussion - Jim
    Jim has a useful diagram he will post in the wiki. Leo will share some diagrams illustrating what is being done at UBC.

Systems of record are authoritative for what they say, but don't have control over what is done with the data they provide. How do we manage the queue, messaging, and service calls in an effective manner?

What are acceptable levels of latency for various systems, how and when do they change, and how are they determined? How are messaging systems and brokers evaluated?

U. Washington is evaluating Amazon Simple Notification Service (Amazon SNS) and Amazon Simple Queue Service (Amazon SQS).

It was suggested that it would be useful to codify requirements for an operational datastore.

Given the breadth of the space, this would be a useful undertaking to knit together the various threads.

Q: What about higher-ed warrants its own reference architecture?
A: Distinct vertical, focused on learning and research; and unique porous/fluid set of communities being served, different from gov't and private sector.

Industrialization of research and learning were cited as long term trends affecting higher ed and EA, e.g. organizing research in a systematic way to achieve defined goals, and research as a funding source. This has implications in how supporting systems can and should be structured.

Soliciting the involvement of an established EA group (e.g. OpenGroup?) was proposed, as was talking to JISC about some related work under their umbrella.

Feedback on the call was positive. This may be a good topic for the F2F.
