A minor point, but the wording of the following bullet point in Section 5 of
Concepts [1] seems ambiguous:

    Some properties may change over time. A relationship that holds between two
    resources at one time may not hold at another time.

The first sentence can too easily be read as saying that properties
_themselves_ change, whereas: "An IRI, once minted, should never change its
intended referent".  Perhaps something like the following is intended:

    A relationship that holds between two resources at one time (i.e., a
    property) may not hold at another time.

This fits with the earlier characterization of a property as "a resource that
can be thought of as a binary relation". [2]
