How to create a dynamic attribute schema in FME?
This scenario is a way to construct an attribute schema using lists in FME. The schema is defined by using attributes in the list, for example: When a feature with such attributes is sent to a dynamic Writer, then this schema is used in preference to any other.
How are FME attributes turned into format attributes?
When writing data, FME attributes are turned into format attributes that reflect the data as it is supposed to be written. However, you can override this process by predefining the value of these attributes before they are sent to the writer. In other words, setting a format attribute may cause a transformation in the data to take place.
What is the definition of data transformation in FME?
Data Transformation is FME’s ability to manipulate data. The transformation step occurs during the process of format translation. Data is read, transformed, and then written to the new format. FME Workbench provides many options to control data transformation.
Where does the dynamic translation schema come from?
In general, the schema for a dynamic translation will come either from the source dataset itself, or from a different dataset (such as the database table the data is being written to).
How does FME fill in the schema mapping?
In most cases, FME automatically fills in basic schema mapping in a new workspace. The schema mapping can then be edited as required. In Workbench’s intuitive interface, feature type and attribute connections are made by dragging connecting lines between these parts of the schema.
How are attributes defined in schema safe software?
Click the Parameters tab to view the feature type name, the name of the parent dataset for the feature type, and permitted geometry types. Above: The User Attributes tab shows a list of attributes present on the feature type. Each attribute is defined by its name, data type, width, and number of decimal places.
When to change feature type in schema mapping?
Change a Dataset (Move a Feature Type): When more than one destination dataset is defined, you can switch a feature type from one destination dataset to another, using the drop-down list under the Parameters tab. Schema Mapping is the means by which a datasets structure can be transformed. What is Schema Mapping?
