Subject: [wsia] [wsia-glossary] Consumer
Title: Message
On our Friday meeting, we discussed the role of the
"Consumer" in a bit more depth, and tried to come up with a few
definitions.
Below I tried to summarize the roles we discussed, I
hope I captured them accurately.
A Consumer may have multiple
roles:
1. Serve as a (visual) container for the
Producer
With the purpose of presenting the Producer to an
end user in a larger "container" page.
2. Customize and adapt the look-and-feel of the
Producer
With the purpose of offering seamless integration with the
"container" page.
3. Augment Producer functionality
With the purpose of presenting an integrated application that
leverages the Producer functionality (e.g., a bank offering Travelers Checks
adds the ability to pay with account debit).
4. Orchestrate multiple
Producers
With the purpose of aggregating multiple producers into
a compound application (e.g., an Address Book Producer and a Mapping Producer
are bound to visually display a person's location).
A few notes:
* Naturally,
a Consumer may also (coincidentally) turn back and become a
Producer of a larger Web Service, however - this seems to be independent of the
basic Producer/Consumer model.
* Although a Consumer typically acts as a
"container" for the Producer WSIA Web Service, this is only one aspect of its
behavior.
