Number

A numeric value, like the size of a piece of land, or the value of a contract. Since all property values in FtM are strings, this is also a string and there is no specified format (e.g. 1,000.00 vs. 1.000,00).

In the future we might want to enable annotations for format, units, or even to introduce a separate property type for monetary values.

Matchable types allow properties to be compared with each other in order to assess entity similarity.

Pivot types are a stronger form of matchable types and can be used to find similar entities based on simple value lookups.
