Hi Bill,

 

I prefer the last format as well.

 

One of the things I just learned from Pete, when he was briefing me on what
I need to know for validating the Schema diagrams in section 5 (System
Configuration) of the draft SM 2.0 document, was that Inter-elemental
Constraints cannot be shown in the XML and the text representation in the
tables is used to describe the constraints.

 

I don't know whether we might want to consider creating a specific section
in the SM 2.0 document for describing the constraints or not.

 

Best Regards,

 

/Paul

I prefer the last format (what was used in the MFD Common Semantics and
Model)...

The Imaging System Semantics and Model V2 will include and update
information from MFD Common Semantics and Model and  the previous Service
specifications. Much of the contents of these documents consists of showing
hierarchical Schema graphics followed by detailed descriptions of the
elements in the diagram.  The earlier documents used three different
approaches for these descriptions, as indicated in the discussion document
posted at

 <ftp://ftp.pwg.org/pub/pwg/mfd/white/table_format_examples.pdf>
ftp://ftp.pwg.org/pub/pwg/mfd/white/table_format_examples.pdf

Each approach had its proponents and detractors. The most common format was
the single row per entry table used in the MFD Common Semantics and model.

 

The Imaging System document should  use a consistent approach for this
explanation of schema elements. Although difficulty in implementing the
format should be considered, it is also important that the approach be
useful and effective in describing the schema.  The three formats are
described to allow a working group consideration and decision, hopefully by
the next Semantic Model WG conference call.

Thanks,

Bill Wagne
