Reader Directives

The suffixes shown are prefixed by the current <ReaderKeyword> in a mapping file.

By default, the <ReaderKeyword> for the World Meteorological Organization GRIB (GRIdded Binary) reader is GRIB.

DATASET

The value for this directive is the name of a single GRIB file.

Typical extensions for this format include .grb, .grib, .grb1, and .grib2.

Mapping File Syntax

An example of the DATASET directive in use is:

GRIB_DATASET “C:\DATA\GRIB\vancouver.grib”

GROUP_BY_DATASET

When the value is set to No, the only feature type this reader will use is the reader type name.

When the value is set to Yes, the feature type of each dataset is the filename (without the path or the extension) of the dataset.

Required/Optional

Required

Values

YES | NO (default)

Mapping File Syntax

GROUP_BY_DATASET “Yes”

Workbench Parameter

Feature Type Name(s)

EXPOSED_ATTRS

This directive allows the selection of format attributes to be explicitly added to the reader feature type.

This is similar to exposing format attributes on a reader feature type once it has been generated; however, it is even more powerful because it enables schema-driven applications other than Workbench to access and leverage these attributes as if they were explicitly on the schema as user attributes.

The result of picking a list of attributes is a comma-separated list of attribute names and types that will be added to the schema features. Currently all reader feature types will receive the same set of additional schema attributes for a given instance of the reader.

Required/Optional

Optional

Mapping File Syntax

Not applicable.

While it is possible for FME Objects applications to invoke this directive, the required format is not documented.

This directive is intended for use in our GUI applications (for example, Workbench) only.
