SACM2 — Model uses undefined ‘date’ type.

Currently, the Artefact, and Activity classes use the type ‘date’ for some of their attributes, and the ‘date’ attribute is missing from the model and diagrams for ActivityEvent, despite appearing in the text of the specification.

Change date to string

In section 12.5.2 (Attributes of Artefact class) change “date: Date” to “date: String”. In section 12.5.4 (Attributes of ArtefactEvent class) add “date: String”. In section 12.5.6 (Attributes of Activity class) change “startTime: Date” to “startTime: String” and “endTime: Date” to “endTime: String”.

See pdf “Model uses undefined date type.pdf” for markup of proposed changes to Figure 2 and 12.1
