For example: if a feature has the following attributes:

Attribute(boolean) : `mybool' has value `Yes'

Attribute(32 bit integer): `myint' has value `12'

Attribute(64 bit real) : `myreal' has value `12.965'

the following list attributes will be added:

Attribute(string) : `attribute{0}.fme_data_type' has value `fme_boolean'

Attribute(encoded: utf-8): `attribute{0}.name' has value `mybool'

Attribute(string) : `attribute{1}.fme_data_type' has value `fme_int32'

Attribute(encoded: utf-8): `attribute{1}.name' has value `myint'

Attribute(string) : `attribute{2}.fme_data_type' has value `fme_real64'

Attribute(encoded: utf-8): `attribute{2}.name' has value `myreal'

The transformer also gives users the option to exclude certain attributes based on name or prefix, and automatically excludes all "fme_" attributes.

Input Ports

Features containing attributes for which a schema definition is required.

Output Ports

All features are output. Attributes which have been selected to be excluded are removed from the feature. The list containing the schema of the feature is added to each feature.

Parameters

Attributes to Exclude

A selected set of attributes that will be excluded from the generated schema list and removed from the feature.

Prefixes to Exclude

A comma-delimited list of prefixes for attributes that are to be excluded from the generated schema list and removed from the feature. Regular expressions are not supported. For example: "date" will exclude any attributes that start with the letters "date" e.g. date_created, dateupdated

Sort Attributes

(Ascending, Descending, None) Set this parameter to alphabetically sort output attributes.

Usage Notes

The feature based schema can be passed to any writer that it set to Dynamic Mode and used with the "Schema from First Feature" setting.
