Modify / Delete: no

An existing network attribute must not be deleted or changed. The attribute domain entries of a network attribute may also not be changed, deleted or expanded.

Justification:

•A change can cause trace configurations to no longer function as expected.

•A change can mean subnetworks can no longer be tracked or created as expected.  

Create: it is possible to create new network attributes.  

In the data model, a "NET_CUSTOM" network attribute of the type "long" is already available for all devices, lines and junctions in each utility. The attribute can be populated and used for network analysis if a customer needs another network attribute. This would avoid the need for a model extension.

However, if you still want to create a new network attribute, the following naming convention applies:

•New network attribute:  

CUS_NET_<AttributeName> 

•This then refers to a field of the same name for a feature class.

Attribute name on the feature class: CUS_NET_<AttributeName>

•If the attribute pulls values from an attribute domain, the “CUS_” prefix precedes this attribute domain. Do not forget to add/assign this attribute domain to each subtype!  

CUS_<AttributeName>
