Esri ArcGIS Feature Service Reader Parameters

Web Connection

If the Authentication Type is Web Connection, specify the Web Connection to use.

Authentication Type

Site URL

The host URL of the ArcGIS Enterprise Installation. This is expected to include the Web Adaptor name. For example:

https://YOUR_HOST_NAME.com/portal

Authentication Type

URL

Specify the fully-qualified URL for the Feature Service to read. For example

https://services1.arcgis.com/organizationID/arcgis/rest/services/featureservicename/FeatureServer

Item Source

Determines whether the feature service to write to will be specified using a user folder or a group:

• User Content (default) – Select this option when selecting this feature service from a user folder.
• Group – Select this option when selecting a feature service from a Group.

Folder

Specifies the name of the folder in which the feature service is contained.

The default value of / (forward slash) represents the root user folder. Clicking the Browse button will display a list of a user’s folders.

Group

Specifies the ID of a group for an existing feature service. Clicking the Browse button will display a list of the groups a user belongs to, as well as all the groups in their organization.

Feature Service

This parameter is used to specify a single feature service. Clicking the Browse button will display a list of all the feature services in the selected group or user folder. Once selected, the Feature Service Item ID will be appended to the name of the feature service.

Assuming the correct user folder is selected, these are all valid ways to specify an existing feature service with name My Feature Service and ID 567aba67c25cb60ee159d3fbe2b16eff:

• My Feature Service(567aba67c25cb60ee159d3fbe2b16eff)
• (567aba67c25cb60ee159d3fbe2b16eff)
• My Feature Service

After you have entered a valid Feature Service, click the Browse button to select layers or tables for import. A connection window appears while the system retrieves a list of layers and tables from the selected Feature Service.

Once the list appears, you can select one or more layers or tables, and then click OK to dismiss the window. Their name(s) will appear in the Layers parameter.

Specifies whether to add a label attribute for each coded domain attribute on the layer. For instance, the coded domain attribute foo would result in an extra attribute foo_resolved that contains the label corresponding to the coded value of the foo attribute. Coded domains defined as part of layer subtypes are supported.

Esri ArcGIS Feature Service writers automatically recognize label attributes when working with existing Feature Services. If a valid label value is provided, and no value was provided for the corresponding coded domain attribute, then the coded domain attribute is set based on the label value. If there is no corresponding coded domain attribute, then the label attribute is treated as a regular attribute.

Values: Yes or No

Default: No

Specifies the maximum number of features that may be present in a single response from the server. Reduce this value if reads are failing due to timeouts.

The value for this parameter is capped to the maxRecordCount property on the Feature Service.

Default: 1000

Specifies whether the reader should verify HTTPS Certificates:

• Yes
• No
• Use Web Connection Value – The parameter uses the Verify SSL Certificate parameter defined in the web connection.

Additional Attributes to Expose

Use this parameter to expose Format Attributes in FME Workbench when you create a workspace:

• In a dynamic scenario, it means these attributes can be passed to the output dataset at runtime.
• In a non-dynamic scenario, this parameter allows you to expose additional attributes on multiple feature types. Click the browse button to view the available format attributes (which are different for each format) for the reader.

Alias Mode

This parameter controls how field aliases are used.

• None – (default value) Field aliases are ignored.

• Replace Attribute Names with Aliases – (only applicable when adding a Reader) Attributes on feature types will be named for their aliases rather than their official names. An arcgisfeatureservice_feature_type_alias attribute will be included on each feature. Use this mode when the target format should create feature types using the aliases as attribute names.

  Note  

  To change the alias mode after you select Replace Attribute Names with Aliases, remove the reader from the canvas and re-add it with your preferred alias mode setting.

• Expose Aliases as Metadata Attributes – For each attribute read, a second <name>_alias attribute will be added that stores the alias for the attribute in question. An arcgisfeatureservice_feature_type_alias attribute will also be included on each feature. Use this mode when the target format is a Feature Service format and the aliases should be preserved during feature type and table creation.
Note  

If you want to make changes after you select Expose Aliases as Metadata Attributes, you can only change the setting back to None. To change the alias mode to Replace Attribute Names with Aliases, remove the reader from the canvas and re-add it with your preferred alias mode setting.
