[OSM-talk] About attribution to authors

[Mike]

Let's say, someone prepares data by recording it in the field, and then 
adds another value to data by sorting it out, fixing it and adding more 
information and details. And then he wants to include that data to 
OpenStreetMap.

What is mean of giving proper author attribution? All I can see is that 
OpenStreetMap is presented in copyright notes, not actual authors. The 
only way I found out to see author attribution is to download openstreet 
data and then search there.

I understand that making attribution to all authors at once is problem 
due to large number of involved authors, but there should be some way to 
give proper attribution to real persons who contribute to OpenStreetMap.
