Glossary

Project : One self-contained world with its own graph, types, layouts, calendars, and time.

Node : A thing in the world, such as a person, place, faction, item, or idea.

Edge / relationship : A directed connection from one source node to one target node.

Type : A reusable classification for nodes or relationships. Types can attach properties.

Property : A named, structured value on a node or relationship.

Data type : A reusable schema for a structured or enumerated property value.

Graph : All project nodes and relationships. Tables and layouts are views of this shared data.

Layout : A saved visual arrangement or spatial view of graph data.

Relational layout : A freeform node-and-connector diagram.

Spatial layout : An owner-linked layout with geometry, images, styling, layers, links, and feature validity.

Owner : The node a spatial layout belongs to. Owner validity can control layout availability.

Geometry feature : A point, line, polygon, rectangle, or image on a spatial layout.

Temporal mode : Whether a layout shows All time or follows the project’s viewed time.

Viewed time / tick : The current internal moment used to project time-aware data. Calendars format ticks as dates.

Validity : The interval during which a node, relationship, or geometry feature is active.

Anchor : A starting node matched by the FIND portion of a query.

Connected node : A target reached by traversing relationships from an anchor.

Hop : One relationship traversal in a connected query.

Epoch : The named origin used by a calendar definition.

Unit and span : Calendar building blocks. A unit can be a fixed multiple or an ordered set of named spans.

Overlay : A repeating label cycle, such as weekdays, that does not change unit lengths.

Leap rule : A conditional adjustment to a calendar span’s length.

Calendar event : A recurring occurrence calculated from ordered recurrence steps.
