Esri Knowledge Graph Writer Parameters

• UPPERCASE – Change all feature type names to uppercase text.
• lowercase – Change all feature type names to lowercase text.
• None – Do not make changes to any feature type names.

• UPPERCASE – Change all attribute names to uppercase text.
• lowercase – Change all attribute names to lowercase text.
• None – Do not make changes to any attribute names.

Coordinate systems may be extracted from input feature data sources, may come predefined with FME, or may be user-defined. FME allows different output and input coordinate systems, and performs the required coordinate conversions when necessary.

For systems that know their coordinate system, the Coordinate System field will display Read from Source and FME will read the coordinate system from the source dataset. For most other input sources, the field will display Unknown (which simply means that FME will use default values). In most cases, the default value is all you'll need to perform the translation.

You can always choose to override the defaults and choose a new coordinate system. Select More Coordinate Systems from the drop-down menu to open the Coordinate System Gallery.

Changing a Reprojection

To perform a reprojection, FME typically uses the CS-MAP reprojection engine, which includes definitions for thousands of coordinate systems, with a large variety of projections, datums, ellipsoids, and units. However, GIS applications have slightly different algorithms for reprojecting data between different coordinate systems. To ensure that the data FME writes matches exactly to your existing data, you can use the reprojection engine from a different application.

To change the reprojection engine, Select Workspace Parameters > Spatial > Reprojection Engine. In the example shown, you can select Esri (but the selection here depends on your installed applications):

ArcGIS geometry has to satisfy certain constraints to be considered valid. For example, polygons must have more than 2 vertices. This parameter allows you to specify whether geometry that breaks those constraints will be simplified to ensure only valid geometry is written.

Note that simplifying geometries can be resource-intensive.

For details on the conditions for invalid geometry and how it is simplified, please refer to ArcGIS documentation: Simplifying a Geometry and Calling the Simplify Method.

The number of features written in each Edit Operation of an Edit Session. Data is sent to the server when each edit operation ends.

Default: 1000

This parameter tells the writer whether it should ignore features that would usually cause the translation to fail. This includes features that are topologically incorrect, are not supported by the writer, or conflict with the definition of the table to which it is to be inserted (that is, they are outside of the geometry envelope specified by the feature class). Additionally, the writer will also ignore polygons, donuts, or aggregates of polygons/donuts that cannot be reoriented.

The default setting is No, which means that failed features are not ignored and will cause the translation to fail when encountered.

This parameter sets the number of features to ignore before causing a translation to fail due to a problematic feature. (However, the translation may still fail for other reasons.)

Values: To ignore all failed features: -1; otherwise 0 or a positive integer.

This parameter allows you to store the failed features to an FFS file for later viewing.

This parameter allows you to specify an FME Feature Store (FFS) file to store any failed features.

This file will be created automatically, but will only be created if there is a failed feature.

This parameter is required when Dump Failed Features to File is set to Yes.

Values: path and filename

If either the path or the filename contains a space, the value must be enclosed in double quotation marks. The filename must end in the extension .ffs.

Enables fast deletes when feature operation is set to Delete.

• Yes – Combines WHERE clause predicates up to a limit of 32K characters at a time. If the limit is exceeded, a new query to the table is created.
• No – Slower deletes by creating a query to the table for each feature.

Determines whether to copy the GlobalIDs from the source table to the destination table, or generate new GlobalIDs for the destination table. The feature operation must be set to Insert.

• Yes – Preserves the existing source feature type GlobalID attributes.
• No – Auto-generated GlobalIDs are assigned to features that do not have one.

Specifies whether to create a connection to an Esri Knowledge database that persists and can be shared by other readers, writers, and transformers.

When set to Yes, the connection will remain open until FME shuts down, even if this writer is finished using it. Otherwise, the connection will be closed when the writer is shut down (unless another reader, writer, or transformer is still using the connection).

Creating a new connection is a resource-expensive operation. Depending on how FME is being used (for example, if there are multiple instances of the reader/writer being used), performance may improve by setting this parameter to Yes.
