[Css-csts] Describing relationships between operations

[Yves.Doat at esa.int]

Good morning John,

I have to admit, that I find quite convenient to define the generic 
interdependency between operations within the operation definitions. 
However and considering that you may have a point, I raised CCR#62 with 
your question.

I propose to discuss your point in January.

Best regards
Yves DOAT

[Css-csts] Describing relationships between operations






Members of the CSTSWG,
I have been looking at the draft document "Procedures Definition for
Cross Support Transfer Services" ("Red Book", October 2006) that was
made available to us before last month's telecon. In looking at the
definition of the operations, I see what I believe to be inappropriate
specification of relationships among operations. For example:

Under 4.6,  START operation:
4.6.1.4          All data delivered following the START but prior to the 
next
STOP (see 4.7) shall be delivered in the order in which they were
received or generated.

4.6.1.5          START is valid only after a successful BIND ...

Under 4.7, STOP:
4.7.1.3          STOP is valid only after a successful START ...

Under 4.8, TRANSFER-DATA
4.8.1.3          TRANSFER-DATA is valid only after a successful START ...

and so on.

I believe that in accordance with our separation between definition of
the operations and definitions of the procedures, these relationships
should be removed from the operation definitions and reflected instead
in the relevant Procedure specifications. 

Best regards,
John
