Metadata

Non-visual information added to geometry in the dataset's file. The metadata can come from the source and/or workflow or it can be added by the user later on.

Metadata owner

The unique piece of geometry in the dataset that contains the metadata.

Owner ID

Used to uniquely identify a metadata owner in the dataset.

Query

A set of conditions on metadata that owners need to match to end up in the query response.

Metadata key / value

This pair makes a single metadata entry.

• Key is a string.
• Value is an object (meaning it can be anything - string, number, object containing other metadata entries…)

Metadata root key / root value

This pair makes a metadata root entry, and is located at the root of the metadata.

Metadata sub-key / sub-value

This pair makes a metadata sub-entry, and is located inside a parent metadata value.

• The number of parent metadata makes the level of the sub-entry (e.g: “group” is at level 1)
• Technically, a sub-entry is an entry.
