Hi! When creating excerpts of OSM data with Osmosis, Osmosis will (depending on flags) chop of ways, i.e. the output will contain ways with only some of the nodes in the way. But looking at the XML there is no way to tell that this has happened. The way still has the same ID and timestamp. There should be a way of recognizing theses chopped of ways, say by adding an incomplete="true" attribute or something.
This question came up on the German mailing list after somebody had used the excerpt as basis for some automated fixing of data. He (IMHO correctly) checked the Osmosis excerpt with current data from the API by comparing the timestamps which were the same. So he assumed nothing had changed and he could safely edit the data. But because of the excerpt process the data he based his decision on, was not correct. This is part of a larger problem. Say you create an extract with only some of the tags or a relation with only some members.
