1. How do we
represent custom/specialized/resource-specific events
a. a specific event messaage element is declared as an
extension of the WSDM event type e.g.
<my:ResourceEvent>
<wef:eventId>...
<wef:priority>...
<my:otherInformation>...
<my:moreInformation>...
</my:ResourceEvent>
b. a specific event message element is declared and
contained in WSDM event element e.g.
<wef:BaseEvent>
<wef:eventId>...
<wef:priority>...
<my:ResourceEvent>
<my:otherInformation>...
<my:moreInformation>...
</my:ResourceEvent>
</wef:BaseEvent>
2. How do we
represent topics for these events
1. case b and wstop:messageTypes points to wef:BaseEvent element and
explanation in the text of the specification says that my:ResourceEvent must be
present in the open content
-- this is apparently not very friendly as a
baked-in undrstanding of what events are produced by the topic is necessary. No
machine-processible description available.
2. case b and wstop:messaageTypes points to my:ResourceEvent and text
explains that it must be wrapped in the wef:BaseEvent
element
-- machine-processible, but implementation semantics is
baked-in
3. case a and wstp:messageTypes points to my:ResourceEvent. no
explanation is necessary in the text
- machine-processible
4. case b and wstop:messageTypes points to wef:BaseEvent element and
wstop:MessaagePattern declares that my:ResourceEvent element must be present in
the open content
- machine-processible
- requires understanding of the dialectable query
expression
5. case b and wstop:messageTypes indicates both wef:BaseEvent and
my:ResourceEvent
- implementation approach is not
clear.
