Good grief - the wiki has no indication that this is the case; <a href="http://wiki.openstreetmap.org/wiki/Key:source" target="_blank">http://wiki.openstreetmap.org/wiki/Key:source</a> . Could someone please confirm that source is a deprecated tag and that it should no longer be used? --ceyockey<br>
<br>
</div>You're right; the documentation didn't reflect that.<br>
<br>
The source tag is one of those things which has changed. We used to<br>
stick a ton of information on the object, but as time has gone on,<br>
we've moved metadata to the changeset.<br>
<br>
Another example of this would be "created_by". Older objects in OSM<br>
have a created_by tag that indicates the editor used to create the<br>
object. Modern editors put that information on the changeset. The<br>
editor community has discussed making "source" a default tag in the<br>
editor when a secondary source is used, for example if you were to<br>
have a Bing imagery layer, "source=bing" would be automatically filled<br>
in.<br>
<br>
"source" has been generally deprecated by use. Editors no longer use<br>
them by default, and most mappers don't use them on objects.<br>
<br>
The fact the documentation didn't reflect that is frustrating and<br>
confusing, but not surprising. I've fixed the documentation and added<br>
a section about the old use.<br>
