OpenRefine/OSM integration hmmm...
Yes, but only one way. Data acquisition. Semi-automated or any "unsupervised" data entry is against community recommendations. It usually causes more problems than it does good. This is a topic for a separate discussion, it can be debated, but personally I wish such tools were not widely available.
Integration for data import is what would be really useful especially for data validation. Here I would have some ideas.
Integration with the
http://overpass-turbo.eu/ service, i.e. creating queries directly in OR to retrieve data. This is where I have benefited most from OR standardising data for my needs. Currently only for points but as we have geojson support this can be greatly extended. I see room for innovation here.
One could also consider a step further, not only integration with OSM, but also with GIS software (of course QGIS), this would significantly broaden the scope of application.
If you have any OSM questions, please feel free to ask.
