Ort-merge: What does "ort" mean?

It's now been quite a few weeks, probably months, since the "ort-merge" work has been going one.  However, I don't think I've ever seen an explanation of what "ort" means.  I know it means "place" in German, but that seems an unlikely usage because git project generally works in English.  I don't know of it as a word in English.  So maybe it's an acronym - ORT.  But what does that mean?

So, can someone please say what "ort" means?

Regards,
Richard.
