Capabilities: Create custom data transformations that are automatically applied to source data
as it is read
Benefits: Save time when performing routine data transformations
FME’s Custom Format feature provides functionality that enables users to effectively define new
formats that consist of existing FME formats and transformation operations.
Custom Formats are often used to combine data from multiple sources, or to create a new view of
frequently-used source data by remodeling the dataset. Since the transformation is applied as the
data is read, the original source data remains unmodified, and no copying, translation, or subsequent
storage of source data is performed.
The required data transformation workflow for a specific source dataset(s) is created once in FME’s
Workbench application, then saved as a Custom Format. The transformation workflow (Custom Format)
can then be selected from the FME Formats Gallery or data import menu and used just as any other
A Custom Format can also be described as a virtual format, a user-defined format, a view, or a skin.
Creating a Custom Format allows you to streamline your work process when the same source
datasets are used consistently, and when the same processing is consistently performed to
remodel the source data into the structure required by the destination system or end user.
Creating a Custom Format allows you to resolve schema mismatches between different
datasets by defining a remapping for each dataset into a consistent schema. A user, for
example, may obtain road data from several sources, each with a different schema. Using
FME’s Custom Format capability they are able to resolve the schema differences and present
a consistent schema to users.
A Custom Format provides a convenient way to package and deliver data to an end user who
simply needs to view the data, without understanding how the data has been processed.
