Format-Specific Attributes
In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Type Attributes), this format also adds format-specific attributes (Format Attributes).
|
Attribute |
Description |
|---|---|
|
xml_topic_guid |
Except for the Version, ProjectExtension, Document, and Extension (TopicLabel, TopicStatus, TopicType, User, SnippetType, Stage, Priority, this attribute should be present in all BCF feature types. The attribute represents the topic GUID. In the BCF zip archive, it is the name of the topic directory. |
|
xml_viewpoint_id |
This attribute should be present in viewpoints and snapshot features types. A topic may have one or more viewpoints. The first, default, viewpoint in a topic is composed of a viewpoint.bcfv and a snapshot.png file. Any of the following values will route the viewpoint and snapshot features to their default files:
Subsequent viewpoints and snapshot files must be identified by a unique GUID. The GUID determines the viewpoint and snapshot file names in the topic. For example, if the xml_viewpoint_id for the viewpoint features and the Snapshot feature has the GUID value A7693B7D-CFA3-4355-8E0E-5B618F497C4E, then the features were read from, or will be written to, the following viewpoint and snapshot files: A7693B7D-CFA3-4355-8E0E-5B618F497C4E.bcfv A7693B7D-CFA3-4355-8E0E-5B618F497C4E.png |
Geometry Features
The geometry features produced by the BCF reader can be identified by the xml_type attribute. The valid values for this attribute are:
|
xml_type |
Description |
|---|---|
|
xml_no_geom |
FME Feature with no geometry. Every BCF feature type except for the Snapshot feature will have its xml_type set to xml_no_geom. |
|
xml_raster |
BCF PNG Snapshot features. |
Feature Types
The feature types for the BCF reader and writer are listed below. These are FME feature representations of the various XML and PNG files in a BCF dataset.
