Based on internal discussion, change:

• hasPart to isPartOf (also hasDirectPart to isDirectPartOf)
• hasMember to isMemberOf
• Check for others

Some of us think that we made the wrong decisions in some cases when selecting which member of a pair of inverses to keep and which to remove. In general, we believe that the child-to-parent principle should be the determining factor in all cases, whereas in the initial implementation we brought in other considerations. This will also make our policy uniform and coherent.

The old properties can be deprecated or deleted, depending on whether this gets done in a minor or major version.
