In addition to the generic FME feature attributes that FME Workbench adds to all features, this format adds the format-specific attributes described in this section.
The Azure Table feature attributes consists of the columns that were in the Microsoft Windows Azure Table. All features contain an azure_table_type attribute, which is always set to azure_table_none as there is no geometry to Windows Azure Table features.
The following table summarizes the attribute types supported:
|
Parameter |
Contents |
|

Text attributes store variable length strings. This type is also used to store date values. |
|

Integer attributes store integer numbers in contrast to floating point numbers. |
|
boolean |
Boolean attributes store true or false values. |
|
