Writer Feature Type Properties: User Attributes

For information on the parameters in this dialog that are specific to all formats, see About Writer Feature Types: User Attributes

The file names of the physical IFF files are constructed by using the folder specified in the Reader Dataset, the basename specified in the IFF feature type properties, and the .iff extension.

The following table shows the attribute types that are supported.

Name

The name of the IFF file to be written.

Type

Choose one of the following field types.

Width

The width parameter controls the maximum characters that can be stored by the field. For the number type, the width parameter is the total number of characters allocated to the field, including the decimal point.

 

Index

Writing Attribute Indexes

The Shapefile writer can index shape data by attribute and produce attribute index files. These files are named as <featureClass>.<attributeName>.atx. FME attempts to index all attributes that are flagged as INDEX in the user attributes tab of the Shapefile Feature Type Properties.

Any attribute of type char or number that is indexed must be maximum 80 characters wide. Additionally, attribute names cannot contain characters that are illegal in Windows filenames.

If any attributes are flagged for indexing, FME automatically produces spatial index files for the feature type, regardless of the Write Spatial Index setting in the writer parameters dialog. For more information, see the writer parameter Write Spatial Index.

Writing attribute indexes requires that FME is running on a machine with ArcGIS installed.
