BTW, a CONOPS isn't provided to fix REST vs RPC like
problems. One assumes those decisions are made or that
the CONOPS absolves that by specing the format of the
message.
CONOPS can solve the problems of having multiple events
or transmissions that must aggregate into some kind
of whole based on the history. For example, multiple
transactions to assemble the history of a given
person such as a background check. There are multiple
sources, multiple requests, multiple receipts, response
latency, and no particular order, but the assembly
must be chronological. You can need contracts for:
o Specified receipt format regardless of origin OR
method of request
o Specification of who/where assembles the aggregate
o Contract for who delivers the aggregate and in
what format if multiple formats are acceptable,
and the destination of the receipt
Parties who sign up for this have a concept of
operations for a sharable service. Beyond the above,
there will be privacy contracts as well. This isn't
operational per se, but part of the contracting
required to use the service. One flaw in the
descriptions of web services as I've noted before
is the idea that they are available to anyone
anytime anywhere. That won't work.
1. Some services and kinds of information can
only be used by qualified and authenticated users.
Note "qualified". You have to be an approved member.
2. Some services for the same types of information
do not share the same CONOPS. Again, if you live
in the UK, you may not want a Chinese service for
using your checking account. Different governments
have different regulations. Same for elections.
Some countries don't have them or if they do, won't
sign up to services that audit them.
This is why the name "Web services" may be inappropriate.
If "the Web" is defined by the principles of that application's
designers, then many of these services are Internet services
and inappropriate for services that would run according
to those principles. Openness, ubiquity, and anyone/anywhere/anytime
are not qualities that can be sustained in some business transaction
types. It sells well but isn't reality.
Balmer needs to pay attention to that.
