Glossary

Project : One self-contained world with its own graph, types, Scopes, 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. Scopes and layouts refer to this shared data, but spatial manifestations are not graph relationships.

Scope : A view of graph nodes, independent of how those nodes are represented. Global contains the whole graph; additional Scopes contain selected nodes.

Global Scope : The fixed, non-deletable default Scope that always includes every current project node.

Canvas : A freeform node-and-connector representation of a Scope. Each Canvas keeps its own positions, routes, and viewport.

Layout : A saved Canvas or spatial view of graph data.

Spatial layout : An owner-linked local coordinate space with geometry, images, styling, manifestations, navigation links, and manifestation validity.

Project space : The Atlas coordinate system into which local spatial layouts are translated.

Atlas placement : The project-space position of a spatial layout’s local origin. Moving it translates the whole layout without changing local geometry.

Atlas detail scale : The units-per-screen-centimetre threshold at which a spatial layout appears on Atlas. Smaller values appear closer in.

Spatial unit : The project-wide meaning of one integer coordinate step.

Spatial grid : A spatial layout’s square, pointy-top hex, or flat-top hex reference grid. Its cell edge size is measured in the project’s spatial unit, and its lines can appear below or above layout content.

Spatial manifestation : A point, line, polygon, rectangle, or image on a spatial layout. It may bind to a node and manifestation type, link to a relationship or layout for navigation, or remain unbound as decoration.

Manifestation type : A project-defined spatial meaning for a manifestation, such as Representation, Habitation, Political control, Vegetation cover, or Species distribution.

Decoration : A spatial manifestation without a node, relationship, or layout binding. It remains visible but adds no node to graph queries.

Owner : The node a spatial layout belongs to. The owner’s start controls when a Follow project layout becomes available.

Temporal mode : Whether a Canvas or spatial 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 : A period during which a relationship, spatial manifestation, property value, or text version applies. Nodes have a start only.

State : The set of property values and text versions that apply to an element at the viewed time. Death and other states use ordinary properties.

Version : One value or text block revision with its own period. Corrections edit a version; dated changes add another.

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.
