String

DSID

(Solo lectura)

The dataset ID.

Integer

extent

(Solo lectura)

The Extent object.

Nota:

extent is available for spatial datasets only.

Extent

isArchived

(Solo lectura)

Specifies whether the dataset has been archived. isArchived is only supported for an enterprise geodatabase.

Boolean

isVersioned

(Solo lectura)

Specifies whether the dataset is versioned.

Boolean

isTraditionalVersioned

(Solo lectura)

Specifies whether the dataset is traditional versioned.

Boolean

isBranchVersioned

(Solo lectura)

Specifies whether the dataset is branch versioned.

Boolean

MExtent

(Solo lectura)

A space-delimited string (minimum m-value, maximum m-value).

Nota:

MExtent is available for spatial datasets only.

String

minimumRequiredClientVersion

(Solo lectura)

Specifies the minimum version of ArcGIS Pro required to open the dataset.

Nota:

This property represents the minimum client version to access the dataset. For example, a value of 13.4 represents version 3.4 for ArcGIS Pro and version 11.4 for ArcGIS Enterprise.

The default value of 10.0 is used for unregistered datasets.

String

spatialReference

(Solo lectura)

Returns the SpatialReference object for the dataset.

Nota:

spatialReference is available for spatial datasets only.

SpatialReference

workspace

(Solo lectura)

Returns a Describe object with the properties of the input dataset's workspace.

See Workspace properties for specific workspace-related Describe details.

Nota:

Use this property to determine workspace properties for many data types including layers, and feature classes in a geodatabase that may or may not be in a feature dataset.

Dataset properties example

The following stand-alone script displays dataset properties for a shapefile.

import arcpy

# Create a Describe object from the shapefile
desc = arcpy.Describe("C:/temp/xy.shp")

# Print dataset properties
print(("Dataset Type: {0}".format(desc.datasetType)))
print(("Extent:\n  XMin: {0}, XMax: {1}, YMin: {2}, YMax: {3}".format(
    desc.extent.XMin, desc.extent.XMax, desc.extent.YMin, desc.extent.YMax)))
print(("MExtent: {0}".format(desc.MExtent)))
print(("ZExtent: {0}".format(desc.ZExtent)))

print(("Spatial reference name: {0}:".format(desc.spatialReference.name)))
