Use of managed_data_deleted

[Michael]

We have a need to accommodate concurrency and collaboration between
two applications and were hoping to be able to use the
managed_data_deleted entity. It appears, though, that this entity
will not be useable. Here's the scenatio:

1 Application A creates structure and export it to Application B via
the CIS/2 standard
2 Application B modifies the structure, say, adding details, and sends
it back to Application A
3. Application A reviews the changes made by Application B and finds
some unnecessary structure

How does Apllication A indicate to Application B that some members
need to be deleted?

I had thought that the managed_data_deleted entity was ideally suited
for this purpose, but that was when I thought it was part of the
managed_data_item's history. Instead, it belogs in the
managed_data_items data_item filed and it appears to dead end there.
How do I indicate that a specific
assembly_design_structural_member_linear entity is to be deleted?

Mike,

I haven't looked at managed_data_deleted in a long time, but the
intention of that entity and other similar ones are to maintain a
history of changes to a CIS/2 model. They are not intended to
indicate that status of a part, such that it might be deleted. To
assign a status to a part, you could use item_property and
item_property_assigned. You can create any property you want. Of
course you have to work things out with the receiving application and
agree on the attributes of the property.

The entity managed_data_deleted allows the item of data associated
with the managed_data_item to be declared as deleted. This allows the
meta-data associated with the data to be maintained after the item of
engineering data has been deleted by an application. In such as
event, only the meta-data is exchanged rather than the deleted data
itself. This minimizes the amount of redundant data that will be
exchanged by DMC applications.

It's saying that the data previously imported has been deleted by an
application. This entity is to be used with the other data managment
constructs described in Chapter 19 of SCI-P268.
