When defining the value lists or the content of the attribute domains, the following is used as a guideline:

- Code value "0" is reserved for "unknown" value

- Code value "1" is reserved for  "other" value

Coding within the feature class must remain unique for the AssetEntity attribute field, which is used to provide a subcategory or more details for the asset type. As a result, the following schema is used to define the code values:

  <Asset type or asset group code>Enumerated 2-digit number

Example

FlowControlDevice (Assetgroup 300), Valve (Assettype 302)

 30202 Flap Valve

 30403 Gate Valve

 30204 Ball Valve

 30205 Valve
