I don't understand this.

What is "the user request"? Are you talking about the API of the CA Client Library?
Didn't we agree that DataAccess would be the interface to the channel data?

Clueless,

We have still not created the user request. In an effort to get this started can we put some thing on a wiki page let's make the categories:
Connect
Get
Put
Monitor
Any others?
First attempt - connect..... Please build on this until we have it.


Connections:

Request		Connect
Argument			channel name
Return			id, quality, data_type, number_of_elements, access
					id - channel id used as a handle
					quality - is this the IOC, a gateway, backup/primary
					data_type - one of a well know set of data types
					number_of_elements - if this is an array -
					access - do I have access or not

Request		Match
Argument			regular expression
Return			number of matches, array of: id, quality, data_type, num_elm, acc
(as in first expample)
