Have you wondered if a certain dataset can be used for OSM? What does it mean for a license to be “compatible” with OSM and ODbL? This talk will give pointers on where to look for information, common compatibility issues, and best practices for presenting a license to LWG for help review.

The talk would go over tips for mappers to help them think through potential license issues for imports. The tips would cover all the major steps for determining compatibility: identifying the data's license, check OSM-related history, identifying/resolving compatibility issues, and achieving community consensus.
This talk will be useful for any mapper with compatibility questions or who is interested in importing open data into OSM.
