RE: [plcs-dex] USe of /IGNORE

[Tim Turner <tjt@lsc.co.uk>]

I think this is the same interpretation as the PDM schema - with which we should be consistent unless there are good objections.

 

We then need to reflect in the templates also - where I'm sure there are some typos...

Tim

Subject: [plcs-dex] USe of /IGNORE

Hi

There has been some confusion about the use of /IGNORE (certainly in my mind).

 

My understanding is:

In general, attribute values are set to '/IGNORE' when the information that could be held be the attribute is instead assigned to the instance of the entity.

 

So any OPTIONAL attributes that do not have a value assigned (by identification_assignmnet or classification_assignment for example) should be set to $.

 

Does everyone agree?

 

BTW – this is documented in the help files

 

Value	Description
''	indicates user data managed by the sending system but not provided for data exchange.
'/NULL'	indicates user data in a mandatory attribute that is not managed by the sending system or currently not known.
'$'	$ is used in the physical file, if an optional attribute is not instantiated.
'/IGNORE'	Attribute values are set to '/IGNORE' when the information that could be held be the attribute is instead assigned to the instance of the entity.

Table — Attribute values

 

Regards
Rob
