Name

A descriptive name for the input connector used for reference in GeoEvent Manager.

Input Folder Data Store

The registered system folder under which files will be found.

Input Directory

A subfolder directly under the registered system folder. Input Directory should be left blank if a subfolder under the registered system folder does not exist.

Input File Filter

A regular expression pattern used to identify files appropriate for this input to ingest and adapt to create event data records for processing. The default is .*\.json, which matches any filename (.*) ending with the literal suffix (.json).

While this parameter is not required and can be left blank, it is recommended you specify a pattern which matches the file name of any file whose schema matches the GeoEvent Definition this input has been configured to use and exclude files (by name) which you do not want the input to ingest.

Default Spatial Reference

The well-known ID (WKID) of a spatial reference to be used when a geometry is constructed from attribute field values whose coordinates are not latitude and longitude values for an assumed WGS84 geographic coordinate system, or geometry strings are received that do not include a spatial reference. A well-known text (WKT) value or the name of an attribute field containing the WKID or WKT may also be specified.

Include Subfolders

Specifies whether subfolders under Input Folder Data Store and Input Directory (optional) are used for files. The default is Yes; however, organizing data with different schemas into different folders and changing this parameter to No, to disable recursive search, allows a simpler configuration.

• Yes—Recursively search for files whose content will be ingested and adapted to create event data records.
• No—Only the Input Folder Data Store and Input Directory (optional) subfolders will be searched for files.

Delete Files After Processing

Specifies whether the files in the registered system folder will be deleted after their content has been processed. Note that even if a file's content cannot be adapted, no event records are created, and no real-time event processing occurs, the inbound transport will still delete a file whose contents were successfully read. The default is No.

• Yes—Files will be deleted from the registered system folder after being processed.
• No—Files will not be deleted from the registered system folder after being processed.

Files not deleted will be reread, from the beginning of the file, if the input connector's properties are changed and saved or if the input is stopped and restarted, for example, if the ArcGIS GeoEvent Server service is restarted.

Create GeoEvent Definition

Specifies whether a new or existing GeoEvent Definition should be used for the inbound event data. A GeoEvent Definition is required for GeoEvent Server to understand the inbound event data attribute fields and data types.

• Yes—A new GeoEvent Definition will be created based on the schema of the first event record received.
• No—A new GeoEvent Definition will not be created. Select an existing GeoEvent Definition that matches the schema of the inbound event data.

GeoEvent Definition Name (New)

(Conditional)

The name assigned to a new GeoEvent Definition. If a GeoEvent Definition with the specified name already exists, the existing GeoEvent Definition will be used. The first data record received will be used to determine the expected schema of subsequent data records, a new GeoEvent Definition will be created based on that first data record's schema.

The parameter is shown when Create GeoEvent Definition is set to Yes and is hidden when set to No.

GeoEvent Definition Name (Existing)

(Conditional)

The name of an existing GeoEvent Definition to use when adapting received data to create event data for processing by a GeoEvent Service.

The parameter is shown when Create GeoEvent Definition is set to No and is hidden when set to Yes.

Expected Date Format

The pattern used to match expected string representations of date/time values and convert them to Java Date values. The pattern's format follows the Java SimpleDateFormat class convention.

While GeoEvent Server prefers date/time values to be expressed in the ISO 8601 standard, several string representations of date/time values commonly recognized as date values can be converted to Java Date values without specifying an Expected Date Format pattern. These include the following:

• "2019-12-31T23:59:59"—The ISO 8601 standard format
• 1577836799000—Java Date (epoch long integer; UTC)
• "Tue Dec 31 23:59:59 -0000 2019"—A common web services string format
• "12/31/2019 11:59:59 PM"—Common format used in the United States (12-hour clock)
• "12/31/2019 23:59:59"—Common format used in the United States (24-hour clock)

If the date/time values received are expressed using a convention other than one of the five shown above, you will have to specify an expected date format pattern so GeoEvent Server knows how the date/time values should be adapted.

Construct Geometry from Fields

Specifies whether the input connector should construct a point geometry using coordinate values received as attributes. The default is No.

• Yes—Values from specified event attribute fields will be used to construct a point geometry.
• No—A point geometry will not be constructed. It is assumed an attribute field contains a value that can be interpreted as a geometry or the event record is nonspatial (does not have a geometry).

X Geometry Field

(Conditional)

The attribute field in the inbound event data containing the x coordinate part (for example horizontal or longitude) of a point location.

The parameter is shown when Construct Geometry from Fields is set to Yes and is hidden when set to No.

Y Geometry Field

(Conditional)

The attribute field in the inbound event data containing the y coordinate part (for example vertical or latitude) of a point location.

The parameter is shown when Construct Geometry from Fields is set to Yes and is hidden when set to No.

Z Geometry Field

(Conditional)

The name of the field in the inbound event data containing the z coordinate part (for example depth or altitude) of a point location. If left blank, the z value will be omitted and a 2D point geometry will be constructed.

The parameter is shown when Construct Geometry from Fields is set to Yes and is hidden when set to No.

JSON Object Name

The name of a JSON element that can be used as the root node of a substructure within the received JSON data. When JSON Object Name is used to specify a JSON element by name, the adapter will search for substructures whose object name matches the specified element name. Only data within the identified substructure will be considered. When left blank, which is the default, the uppermost JSON object is used as the root of the entire JSON structure.

Learning Mode

Specifies whether Learning Mode is active or disabled. When Learning Mode is set to Yes, the inbound adapter will append new fields to a GeoEvent Definition it has created and is maintaining.

• Yes—Learning mode will be enabled. The GeoEvent Definition will be updated with new fields from event records sharing different schemas.
• No—Learning mode will not be enabled. The GeoEvent Definition will not be modified.

Learning Mode can be useful when you need to allow the input connector to modify a GeoEvent Definition it has constructed. The purpose of this parameter is to temporarily accept that event data received will have a variable schema or data structure. The input connector will use a sample of received data records to learn more about the variable data structure and append new, previously unobserved, attribute fields to an existing GeoEvent Definition.

Read File as Text Lines

Specifies how the content of the file should be read and parsed. The default is Yes.

• Yes—The contents of the file will be read and parsed as individual lines of text.
• No—The entire file will be read and parsed as a complete document.

When working with a text file with one or more JSON array objects, it is recommended that you read the entire file's content rather than read the file's individual lines of text. JSON documents are best read as a single document.

Max Number of Lines per Batch

(Conditional)

The maximum number of lines to read from the file in each batch or interval. The default is 1000 lines. Reduce this value if each event record contains many attributes to limit the amount of data sent to the Text adapter as a batch.

The parameter is shown when Read File as Text Lines is set to Yes and is hidden when set to No.

Batch Flush Interval (milliseconds)

(Conditional)

The number of milliseconds to wait before reading another batch of lines from the file. The default is 500. Reduce this value if file size is expected to be very large or if additional time is necessary to process each batch of lines retrieved from a file.

The parameter is shown when Read File as Text Lines is set to Yes and is hidden when set to No.

Number of Lines to Skip from Start of File

(Conditional)

The number of lines to skip from the start of the file. The default is 0. Increase this value if you want a skip a specific number of lines—for example, header lines specifying attribute field names or data types, because they do not contain actual data for processing.

The parameter is shown when Read File as Text Lines is set to Yes and is hidden when set to No.

As GeoJSON

Specifies whether to parse the incoming geometry as a GeoJSON geometry object rather than as feature JSON. The default assumes that when a geometry is received as a string, the value will be feature JSON as described in Geometry objects.

• Yes—The incoming geometry will be parsed as GeoJSON rather than feature JSON.
• No—Received string representations of a geometry are assumed to be feature JSON.

Refer to the GeoJSON specification for valid and complete examples of GeoJSON geometry object formats. A single GeoJSON geometry object is assumed to have a member with the name coordinates whose value is an array. The structure of the array is determined by the type of geometry.
