I'm trying to follow the directions to recreate the diagram in Lab 4, slide 24
In the model notes there is a textual constraint:
For each Project: existing completionDate >= startDate
I believe startDate and completionDate are supposed to be role names. in the PPT, these are shown as bracketed blue text by the respective FactTypes. I can't get these labels to display on the diagram. For both fact types, I set DisplayRoleNames to On, and set their respective Note properties to startDate and completionDate.
Also the fact types are named ProjectStartedOnDate and ProjectCompletedOnDate. Is there a way to rename them so that they are startDate and completionDate ?
The PPT shows footnote numbers refering to the textual constraint in the model note; I don't expect to recreate them since it is stated on the previous slide that footnoting is not yet supported. Likewise for the * in the derivation rule for 'is completed'
However, it concerns me that there are boldface keywords shown that do not display in the text that I added to the notes. Does this mean I am doing something wrong?
Thanks,
Joe
