I've seen research papers (Haklay 2010) using the data regarding the number of edits (or the contributors working on) on the features of OSM. I am using QGIS and download the area I want to study. However, data obtained this way are limited to shapefiles. How could I systematically obtain the number of edits made on each feature of OSM? This information have been used as a proxy for the data quality of OSM, which is something I want to evaluate.
