Bicycle racks would certainly be a welcome addition. I look at the
number around UVic and shudder.

However, who holds copyright on the data? They need to sign off on
importing it into OSM if it isn't licensed under fairly liberal terms.
If you don't know then it is likely all rights reserved. Plant Ops may
not have the ability to do this. Likely you are going to need to clear
it through Legal, which can add time and headaches.

On all the nodes, so that we can see where they come from

Check the datum and projection. They need to match what OSM uses,
which I currently cannot remember.
