If we want to make queries over quantities and units, we need a way of handling units in an uniform way so we can handle, say "miles per hour" and "km per hour" in the same way.

Also, see also an attempt at an OASIS Stantard that didn't take: https://www.oasis-open.org/committees/tc_home.php?wg_abbrev=quomos -- a very simple analysis of the failure of that TC to reach critical mass is shown https://lists.oasis-open.org/archives/quomos/201408/msg00000.html.
