Feature Representation

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).

The TELEATLASCSV feature attributes consists of the values that were in the schema definition file. All TELEATLASCSV features contain a teleatlascsv_type attribute, which is always set to fme_no_map as there is no geometry to TELEATLASCSV features. This represents that the feature was generated from a TELEATLASCSV dataset.

Attribute Name

Contents

teleatlascsv_type

The CSV geometric type of this entity.

Range: fme_no_map

Default: fme_no_map

The schema definition file, which is in a CSV-like format, will always contain one line. The first value of the line is the feature type name. Subsequent values are the attribute names for the corresponding values in the data file.

An example of a line of a schema definition file is:

4110,2C,[LS,6I]

Here, 4110 is the feature type name. 2C is the attribute name of the first data value in the data file. [RS,6I] is a composite structure with two elements.

An example of a corresponding line in the data file is:

85504,1,[2,65,2651,66,2652]

The first value of the line is the identification number of the feature. This attribute will have an attribute name of ID.

The next value of the line will become an attribute on the feature with an attribute name of 2C and a value of 1. The square brackets delimit a composite structure. The first value, 2, denotes the numerosity of composite structure outlined in the schema definition file as [RS,6I]. These composite structures will be represented by structured list attributes.

The FME feature representation of the example data line together with the example schema definition line, is as follows:

FeatureType: 4110

// Attributes
ID = 85504
2C = 1
LS{0}.LS = 65
LS{0}.6I = 2651
LS{1}.LS = 66
LS{1}.6I = 2652

If the composite structure described in the schema definition file matches the definition of a GDF composite type as defined by the MultiNet Data Model specification, then the name of the composite structure will be assigned a predefined code.
