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.
