ArcGISAttachmentConnector

Connects to an ArcGIS Feature Service to manage attachments.

Jump to Configuration

Typical Uses

  • Attaching images, PDFs, or other files to ArcGIS Feature Service features
  • Updating or deleting existing attachments
  • Listing attachment metadata for validation or logging
  • Downloading attachments for local storage or further processing

How does it work?

The ArcGISAttachmentConnector connects to an ArcGIS Feature Service to perform various tasks:

Action Task

Add

Upload a new attachment.

Delete

Delete a feature’s attachments.

Download

Download an attachment.

List

List attachment details.

Update

Replace an attachment.

Feature URLs

Feature URLs follow this form:

https://<feature_service_url>/<layer_id>/<object_id_of_feature>

They may be obtained with an Esri ArcGIS Feature Service reader (also available in the FeatureReader transformer) and are stored in the arcgisfeatureservice_feature_url format attribute. These may be used to provide values for the Feature URL parameter.

Note that the object ID (not the global ID) is required.

Usage Notes

  • When accessing branch-versioned feature services, the ArcGISAttachmentConnector will only download or modify attachments on the default branch of the feature service. See ArcGISBranchVersionManager.

Configuration

Input Ports

This transformer accepts any feature.

Output Ports

Features with added attributes, as specified in parameters and according to Action:

Action Output

Add

Input feature with details about the new item.

Delete

Input feature with details about deleted attachments.

Download

Input feature with details about the downloaded attachment.

List

Multiple features, one for each attachment on the specified feature, with details about the attachments.

Update

Input feature with details about the updated attachment.

Input features are output here unmodified, in addition to any other output locations (Output or <Rejected>).

Features that cause the operation to fail are output through this port. An fme_rejection_code attribute describing the category of the error will be added, along with a more descriptive fme_rejection_message which contains more specific details as to the reason for the failure.

If an Input feature already has a value for fme_rejection_code, this value will be removed.

Rejected Feature Handling: can be set to either terminate the translation or continue running when it encounters a rejected feature. This setting is available both as a default FME option and as a workspace parameter.

Parameters

Connection

Select or create a Web Connection, connecting to the appropriate Web Service:

  • Esri ArcGIS Enterprise OAuth (Template) - for Esri ArcGIS Enterprise sites

If File Exists

When Download as is File, select a method for handling existing files:

  • Reject: Leave the existing file intact and output the feature via the <Rejected> port.
  • Overwrite: Overwrite the existing file.

Download to Attribute

When Download as is Attribute, specify the attribute to contain the contents of the downloaded item.

Added Attributes

These attributes will be added to the output features:

_downloaded_path

The local path where the downloaded attachment is saved, when Download as is File .

_filename

The filename of the downloaded file.

_file_size

The size of the downloaded file in bytes.

_content_type

Editing Transformer Parameters

Transformer parameters can be set by directly entering values, using expressions, or referencing other elements in the workspace such as attribute values or user parameters. Various editors and context menus are available to assist. To see what is available, click beside the applicable parameter.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters.

Using the Text Editor

The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.

Text Editor

Using the Arithmetic Editor

The Arithmetic Editor provides a convenient way to construct math expressions from various data sources, such as attributes, parameters, and feature functions, where the result is used directly inside a parameter.

Arithmetic Editor

Conditional Values

Set values depending on one or more test conditions that either pass or fail.

Parameter Condition Definition Dialog

Content

Expressions and strings can include a number of functions, characters, parameters, and more.

When setting values - whether entered directly in a parameter or constructed using one of the editors - strings and expressions containing String, Math, Date/Time or FME Feature Functions will have those functions evaluated. Therefore, the names of these functions (in the form @<function_name>) should not be used as literal string values.

String Functions

These functions manipulate and format strings.

Special Characters

 A set of control characters is available in the Text Editor.

Math Functions

Math functions are available in both editors.
Date/Time Functions Date and time functions are available in the Text Editor.

Math Operators

These operators are available in the Arithmetic Editor.

FME Feature Functions

These return primarily feature-specific values.

FME Parameters

FME and workspace-specific parameters may be used.
Creating and Modifying User Parameters Create your own editable parameters.

Table Tools

Transformers with table-style parameters have additional tools for populating and manipulating values.

Row Reordering

Enabled once you have clicked on a row item. Choices include:

  • Add a row
  • Remove a row
  • Move current row up one
  • Move current row down one
  • Move current row to top
  • Move current row to bottom

Cut, Copy, and Paste

Enabled once you have clicked on a row item. Choices include:

  • Cut a row - delete and copy to clipboard
  • Copy a row to the clipboard
  • Paste a row from the clipboard

Cut, copy, and paste may be used within a transformer, or between transformers.

Filter

Start typing a string, and the matrix will only display rows matching those characters. Searches all columns. This only affects the display of attributes within the transformer - it does not alter which attributes are output.

Import

Import populates the table with a set of new attributes read from a dataset. Specific application varies between transformers.

Reset/Refresh

Generally resets the table to its initial state, and may provide additional options to remove invalid entries. Behavior varies between transformers.

Note: Not all tools are available in all transformers.

For more information, see Transformer Parameter Menu Options.
