Stephen,

Did you mention property chains in our telecon?

If so, would you mind adding an example to the collection [1] that illustrates your concern for the "directionality" of the current properties?

I added a new section [2] to the directory conventions to handle applying inference and querying their results.

Thanks,
Tim

Although "anyone" can define their own inverse of a prov-o property to achieve their property chains, this will inhibit interoperability.
