Figure 1: Relation between HistoricalLocation, Thing(s) and Location(s)

[hylkevds]

In SensorThings API v1.0 (15-078r4) (is that the latest version?) Figure 1, page 21:

• The link between Thing and HistoricalLocation is labeled +things, but a HistoricalLocation can only have 1 Thing. The count (1) is correct, just the word is plural. +thing would be clearer
• The link between HistoricalLocation and Location is labeled +location, but a HistoricalLocation can have many Locations. The cound ( 1..* ) is correct, just the word is singular. +locations would be clearer.
