The description of the parameters part_id_class_name and part_vn_id_class_name is incorrect, and these should refer to the class, not to the library which holds the class.
Comment: (Tim Turner 2007-04-04)
Corrected

There are many businesses where a part or product_as_realized is never versioned, or in at exchange, the version is either, not known, or is not significant, i.e. any version will do as the fit form and function remain the same across versions. However, the templates for representing the part and product_as_realized enforce an identification of a version. I think that we should have a convention for identifying an unkown version and this should be documented in these templates
Comment: (Peter Bergström 2007-04-12)
The capability has a section covering this, under additional usage guide. Let me know if this is not good enough. Do we really have to document this in the template as well? Or do you want a default value of "/NULL" to the version ID? And what do we do about the Part_view_definition and View_definition_context instances that this template instantiates for Parts that have no version - do the Parts ever have properties or sub-assemblies? If so, we need the p_v_d and v_d_c as well. If not, we cannot solve this in one template, and would need a template called "referencing_part_without_version" or similar.
Comment: (Peter Bergström 2007-04-13)
The basic text from the capability has been copied as a note into the description of the template.

There should be a unique constraint that ensures that only one product-category is instantiated.
Comment: (Leif Gyllstrom 2007-05-06)
MAke sure that there's only one instance of Product_category in a data set (i.e. common to all Parts, Breakdowns etc)
Comment: (Rob Bodington 07-05-08)
That is what the uniqueness constraint does.
Comment: (Rob Bodington 07-05-08)
Added uniqueness constraint.

The characterization of a part by part name is not described in the template. This is needed to make the use of correct rdl-class visible.

There should be a uniqueness constraint that force a unique part and version. E.g. Unique constraint: Unique part There shall be at most one instance of the entity (Part) within the data set uniquely identified by a combination of the following template parameters: part_id, part_id_class_name, part_id_ecl_id, part_org_id, part_org_id_class_name. The instance is referenced by the following template parameter: part. Unique constraint: Unique part version There shall be at most one instance of the entity (Part_version) within the data set uniquely identified by a combination of the following template parameters: part_id, part_id_class_name, part_id_ecl_id, part_org_id, part_org_id_class_name, part_vn_id, part_vn_id_class_name, part_vn_id_ecl_id, part_vn_org_id, part_vn_org_id_class_name. The instance is referenced by the following template parameter: version. This rule means that there can be only one version (Part_version) of a part (Part) with any given identifier.
Comment: (Tim Turner 2008-02-25)
The two uniqueness constraints mentioned above have already been provided, in addition to the definition context. However, the definition of the part should also be unique in the context given and of a specific version of the part.

The Unique constraint: Unique product_category States Product_category.name="Part" and Product_category.name = 'part'. This should only be stated once and should should be 'part'. Unique constraint: Unique product_category There shall be at most one instance of the entity (Product_category) with the attribute (Product_category.name="Part") instantiated in the data set. Product_category.name = 'part'
Comment: (Tim Turner 2008-02-25)
Constraint fixed.

The template has the reference parameter: catgy(Type='Product_category') This is not mentioned in the template path. Furthermore, the requirement for this reference parameter is not clear. It is not obvious as to why the Product_category needs to be referenced from outside the template.
Comment: (Peter Bergström 2007-08-15)
I think this ref param was added in the review of the template, because of an ambiguous statement that all entities have to have a reference parameter. I, too, think this ref param should be deleted.
Comment: (Tim Turner 2008-02-25)
The only thing that touches on this is the relationship entity product_category_hierarchy - I think until it has been deemed that this entity will not / shall not be used, we may as well leave this in. It does not add any real overhead, but does allow for other future possible uses that have perhaps yet to be identified or recognized. I have added it to the path.

Comment: (Rob Bodington 08-01-03)
In order to be consistent with referencing_part - recommend using part_id_assgn
Comment: (Tim Turner 2008-02-25)
Added ref params for the part id and version id. However, I think there will be circumstances where the view definition id will also be required.

There should be a unique constraint ensuring that there is only one Part_view of a Part_version with any given View_definition_context. See representing_product_as_realized template
Comment: (Tim Turner 2008-02-25)
I agree, but without being able to uniquely identify the Part view definition, this will be difficult. Each view definition for a Part version may be identified differently and hence need to have an identification assignment provided. I have addressed the issue consistently with the suggestion to follow the constraint in representing product as realized, but I don't think this is really accurate (it should not refer to the product as this is already handled by an other constraint - however there may be several view definitions defined for a version which is not catered for at present).

The template representing_part identifies uniquness constraints for Product_category, Part, Part_version, Part_view_definition and View_definition_context. However there is no uniqueness constraint for the entity Product_category_assignment. This can result in multiple Product_category_assignment for the same instance of Part. There should be a uniqueness constraint on Product_category_assignment that is the same as the one for Product_category e.g. Unique constraint: Unique product_category_assignment There shall be at most one instance of the entity Product_category with the attribute (Product_category.name ="part") instantiated in the data set.
Comment: (Tim Turner 2009-04-28)
It is agreed that in certain scenarios that the absense of a constraint here could present some inconsistencies. However, the constraint cannot be the same as for Product_category because this is a unique constraint against the attribute (name) which is to be constrained to the string 'part'. Product_category_assignment does not have any such local attributes - only attribute relationships. The template language is not rich enough to allow an extended reference to the Product_category entity from Product_category_assignment, so a separate uniqueness rule has been added to ensure that the Product_category_assignment that references the Part is unique.
