My motivation for
writing the comment was that I want to represent the fact that a version of a
part follows on the previous version.
Initially this has
nothing to do with an assembly of parts - it is just about the
part.
Similarly if a Part
is derived from another part, I want to relate the two. Again, this has
nothing to do with an assembly. Hence my suggestion that these representations
should be in the rep_part capability.
Regards
Rob

The relationship between different
version(s) should be described in this capability, not
"representing_assembly_structure" (C003). The product_version_relationship
should be treated in the same way as in representing product as individual,
and use the same classification. I propose: Derived_version_relationship
Sequential_version_relationship Hierarchical_version_relationship as defined
in the PDM Schema usage guide.

Response: Relationships between parts, part
versions and view_definitions are not currently described within
Representing_parts. They are described within representing_assembly_structures
as these relationships are used to define the assembly structures and how
those structures might change if different versions of a part are used.
However, it is possible to include product_version_relationship in this
capability, but it would then exist in both. This is because
supplied_part_relationship (a subtype) would & I believe should, stay
within C003. Though I could be persauded.
I agree with the use of the
classification and the ref data derived from the PDM schema.
Comments?

Tim
