Definitions
A generic class for defining (planned or executed) construction tasks. Instances of this class are connected with the construction element(s), spatial zone(s) or construction damages they operate on (cto:isSubjectOfTask). In addition, they might also be linked to a (planned or executed) moment or time span of performance (prov:atTime/prov:startedAtTime/prov:endedAtTime) and one or more task contexts (cto:hasTaskContext), task methods (cto:hasTaskMethod), assigned persons and/or organizations (prov:wasAssociatedWith), other tasks that must be finalized before the task can start (cto:afterFinishedTask) and reified statements that are added or deleted (cto:resultsInAddedStatement or cto:resultsInDeletedStatement).
