The difference among event source, event source type, event type, event ID is not explicit

[cathyhongzhang]

Suppose the event comes from a AWS S3, what is the event source, event source type, event type, event Identifier? From current definition, it is not very clear.

Can we discuss this in the meeting? I can own and resolve this issue. But I prefer to get other people's input on this first

[duglin]

ok I'll add it to the agenda

@duglin This partially covers what I meant by examples in in the discussion of #41 .
@cathyhongzhang I think similar questions may occur for the other attributes. It might help a lot to create sample flows, where an event travels through a certain system, and for each hop it is described what the values for the attributes are. What do you think?

[duglin]

yep I agree. We ran out of time last week, I'm hoping we can get to it today, but I wanted to ask a similar question about “event-type”, “event-type-version” and “schema-url” since it feels like there might be some overlap between these three things and I wonder if schema-url alone couldn't convey all of the info needed. And if not then we need a very clear definition so there's no confusion about when, and how, to populate them - otherwise we won't get the interop we need.

[cathyhongzhang]

Good idea. A sample flow will help to illustrate issues in our current definition, such as overlap or gap. We may find out that some new attributes, such as correlation-token, need to be defined to really get the interop we need. I will try to draw the flow, show the boundary, and identify issues that need to be discussed. I can probably get this ready for discussion in the 2/22 meeting.

@cathyhongzhang given the PRs we resolved on today's call, I wonder if we can close this one and then if you still think we need more clarity on event-* attribute you can open a new issue that just focuses on those?

[cathyhongzhang]

Ok.
