Subject: [obix-xml] Draft document
0.3
I think it is great there is some energy in
this group. I took a brief look at the proposal we have discussed here
and wanted to toss some things out before the meeting :
http://www.oasis-open.org/apps/org/workgroup/obix-xml/download.php/8995/wd-obix-0.3.doc
I suggest that the SysService use
cases have not been elaborated sufficiently in section 3 to evaluate the
material of 3.1 and on.
Here are some example use
cases:
Get the status of all the fans in the
hvac system.
Get the history
of all the fans status.
Get the lighting
systems status
Get the all dates nighting
building access
Put the lighting system
in conservation mode for 90 minutes
Discover the objects of interest, take the specs home, code and test
against mock objects in the office, then deploy in the field.
Get the history of the lighting system.
This might take 5 years.
Find the obix-compatible systems within the
enterprise
Report on hvac system and security system
histories. It might take 20 minutes to get a response.
I will attempt to comment on sections 3.1 and
on.
<readReq> and <readResp> looks like
messages. Are these going to be soap services (i.e. specified in
wsdl?). In that case, do we need these elements at all? They would
be part of the soap stuff and not the payload.
Do the facets have anything to do with XML Schema
facets?
Should all ids should be URIs?
Can xpath, xquery, or xslt be leveraged to
replace some of the methods of the service? Why not send an xpath as a
service argument? I could see this easily replacing the include
element?
Should we seperate the service from the data
model, define a data model the service queries, then define the
service?
