The source tag is included in the two Python scripts included in this thread.
All I know, is that it is very time consuming to add this data. Looking up what the address may refer to. Checking whether it's next to the street it was intended, etc. And, of course, if there are no other house numbers present yet in our data, one can never be sure that the nodes are placed correctly. It's also not clear whether these addresses are provided by the customers of these companies, or by the company owners themselves. Possibly a little bit of both?
