I do not really understand why revocable license is ODBL compatible that
is not revocable.

I am likely lacking some legal knowledge here.

A revocable license has previously come up in connection with another proposed import of GTFS feeds in North Carolina. [1] In that case, I suspected that the agency was concerned about outdated data lingering. [2] There have also been a few mentions of revocable licenses on various state listings of potential data sources, with a note that this provision probably disqualifies the data from being imported. [3]

I think it would be helpful to get a clarification from the legal mailing list about whether such provisions are in fact problematic. Personally, I've been staying away from such sources, because it would be really tricky if data in OSM would be compliant today but could somehow become non-compliant in the future due to some external factor out of our control. In that hypothetical scenario, redacting the revoked data might incur some collateral damage, as we saw during the ODbL migration.

Matt, if you could explain OSM's constraints to the county GIS office, maybe they'd be willing to clarify these questions for you. In particular, which portion of these terms and conditions apply to use of the site versus reuse of the data downloaded from the site? If it turns out they are concerned about outdated data, tell them about OpenHistoricalMap. ;^)
