Appendix G: Handle System Attributes
- Last UpdatedNov 04, 2025
- 2 minute read
The Gateway creates "System Attributes" that are used to store metadata about the input source and control the behavior of the EIWM Loader. Transformation prevents modification of many of these system attributes. However, transformation can also use these values in filters or update other attributes with their values.
The system attributes can be either of the following:
-
R – The attribute is read only. It is not possible to modify its value.
-
R/W – The attribute can be modified in transformer configuration.
During processing, the Gateway uses these system attributes, as listed in the following table:

Example – Copying of System Attribute to Normal Attribute:
In this example, the attribute #GRAPHICS_FORMAT# is not exportable to EIWM. To include the attribute’s value in EIWM, you can create or re-use a non-system attribute and set its value to the value of the system attribute.
<Attribute>
<Conditions>
<Attribute name="#GRAPHICS_FORMAT#" pattern="^.*$"/>
</Conditions>
<Name value="GRAPHICS_FORMAT" />
<Value value="[#GRAPHICS_FORMAT#]"/>
</Attribute>
The above example will add the engineering attribute named GRAPHICS_FORMAT.
