Hi
Tim
I’m a bit confused as
to which capability you are talking about (numbers always do
that)
C076:assigning_product_properties
C087: is what? It does
not seem to have been checked in.
Are you proposing a
new capability for document properties or are you proposing to extend
“representing_documents”

properties issues?
Hi All, thanks for
the feedback.
i) I guess I wasn't
party to the other discussions but I agree with you that the subtyping does
indicate a difference in how properties are handled.
I can re-use &
reference C076 in C087 and make the distinctions clear. For example, I presume
that we will not need qualifiers such as "predicted" or "required", but would
keep "actual" (e.g. when talking about file-size, page-length etc.,).
However, if we make
changes to C076 in the future this will probably mean changes downstream
also.
ii) Another thing I
just noticed in the module (1126- document_properties), is that it states
A Document_property_representation is a
type of id that conveys the parameters of a
particular aspect of an Assigned_document_property. In fact, a Document_property_representation
is a type of
representation. Is/was this is another
issue?

Hi
Tim
My inclination is
still to have a separate capability for document properties – either as a
separate capability or part of the representing_documents
capability.
We had exactly the
same discussion for process and resource properties and it was concluded
that we should split the properties capability into separate
capabilities:
assigning_process_properties
assigning_resource_properties
Agreed that document
is a subtype of product, however, if you look at the module, you will see
that subtyping has been used to indicate that the document propeorties are
different.
So if we include the
document properties in with product properties then any DEX that is just
dealing with parts will get the document properties as well. Not sure that
this is a good idea.
What does everyone
else think?

1. Module ISO/TS 10303-1126:2004
(Document properties) states;
The document_property_item type is an
extension of the property_assignment_select
type. It adds the data types Document_definition
and File
to the list of alternate data types. However, this type is actually not
present in the PLCS longform as on stepmod at present, or in any previous
version I can find. The document_definition and file entity objects required
for document properties are present in the parent object
though.
Has the former now
been dropped from PLCS? Which is supposed to be
used?
I presume this
is/was either an issue against the module or against the PLCS model.
2. With respect to
the ongoing discussion; if document properties are not to be included in
C076
assigning_product_properties, then can I
suggest that the introduction is misleading as it states
"The purpose of the "Assigning
Properties to Products" capability is to describe how properties are
assigned to products and their subtypes". It then
gives two examples, but is clearly not definitive as to what subtypes are or
are not within scope.

Apologies for the
late reply Rob,
From another
view, document is a type of product and as such should therefore, be
handled by this capability rather than creating or enlarging the scope of
other capabilities that are already becomming too
large.
Also document
properties do not apply to files (digital/hardcopy files) since they are
not subtypes of product & do not have am associated definition, but
cannot use the existing capability because the property_assignment_select
type does not include files. In fact it only includes one of the 18
possible types, which means potentially another 17 capabilities to cover
all!
Documents could
be covered by adding one subtype to the existing capability
(assigned_document_property) & adding two items to the above
mentioned select type (since document_definition is not a subtype of
product_view_definition & files are independantly
defined).
I can create a
new capability or add to existing ones but it would mean repeating a
large amount of information already within
assigning_product_properties.

properties
Hi
An issue was raised against
the capability: Capability
(C076):— assigning_product_properties
that we should include
document properties in it.
Given that we decided to
treat product properties, resource properties and activity properties as
separate capabilities, and given that the document property module
subtypes the generic property model,
it seems to me that
document properties should not be part of
assigning_product_properties
Rather it should either be a
separate capability or part of representing_documents
capability.
Given that you nearly always
want to represent a documents properties whenever you represent a
document and given that document properties will never be used with
anything other than documents, I think that document properties should
form part of the representing_documents capability
Any
thoughts?
Regards
Rob
