The Sub-Objects that have been defined in the Data Model are listed, with a '+' button trailing the name of the Sub-Object. Click on the '+' button to open the Sub-Object as a filter form. Using the 'Sub-Objects: Any' filter form you can create a filter that performs a filter on all available Sub-Objects.

Amount

Specify if a Sub-Object exists, or the amount of Sub-Objects that exist. Use the switch to select All to count all available Sub-Objects (default) or Filter to only count the Sub-Objects matched by this Sub-Object Filter.

Date

Set dates during which Sub-Objects should exist.

Range

Enter two dates in the input fields to specify a range. A date can be entered in the form of e.g. d-m-y, m-y, y, and other formats listed in Object Descriptions under 'Date'.

Chronology

Use the green 'create' button to create a Chronology Statement to be used as a filter.

Change the 'Date' drop-down menu to 'Path' to use another Filter and a Scope to create a relative chronological filter.

Click the grey 'more' button and set the option to Not Empty / Empty to find Sub-Objects that do or do not have a date specified.

Point

Use the numeral operators to find points in time.

Location

Set locations in which Sub-Objects should exist.

Reference

Specify the Type to be used for the Location Reference and select the Sub-Object of this Type used for the filtering. Search for the Object.

Click the grey 'more' button for more settings:

• Set the option to Not Empty / Empty whether a location should contain any reference of the selected Type (optional) or not.
• Specify whether this Location Reference Filter should be applied to find Sub-Objects with the specified reference Self, or should be applied to find Sub-Objects that match their resolved geometry to the resolved geometry from the specified reference Resolve.

Geometry

Paste in GeoJSON data or click the green 'create' button to use an external service to create GeoJSON data.

Click the grey 'more' button for more settings:

• Set the option to Not Empty / Empty whether a location should contain any geometry or not.
• Specify whether this Location Geometry Filter should be applied to find Sub-Objects with a stored and matching geometry Self, or should be applied to find Sub-Objects that match their resolved geometry with the specified geometry Resolve.

Point

Fill in latitude and longitude values, or use the green 'map' button to select a location on the map. Click the grey 'more' button to show an input field to specify a radius to filter on.
