One @context is published per subject. Type and attribute IRIs resolve at /ns/<subject>/<term>.

Common

Shared value types referenced from other subjects: the Japanese address (JapaneseAddress) and the GeoJSON geometry (Geometry).

Disaster response

Data models for municipal disaster response. Currently shelter operation (EvacuationShelter), its own type; the local status wording (statusLabel) uses the task subject's IRI. Linking entities to a disaster-response operation is left to the application (for example refersTo from a task subject Task). Road closures and other road restrictions are RoadRestriction in the transportation subject. Generalised from the data models of Takamatsu City's flood-response application.

Task management

Common model for issue and work tracking. Task, Project, Comment, Attachment. The core holds only what issue trackers, calendar to-dos and municipal work orders share; state and priority follow RFC 8984 (JSCalendar). Location is not limited to points. System-specific terminology is handled with aliases.

• Attachment — Attachment
• Comment — Comment
• Project — Project
• Task — Task

Data models for roads and traffic, based on national standards (the National Police Agency's traffic regulation data format and MLIT's Road Information Provision System). Currently road restrictions (RoadRestriction). The local status wording (statusLabel) uses the task subject's IRI.
