OpenDDR's URL has been inactive for quite a long while (suspended) but their API code was accepted into Apache's "DeviceMap".
The WURFL data and schema thing was never resolved: they never removed it. Their Twitter feed claims "the status is definitely active updated data sets have been always released monthly since first release!", and the Github would bear that out.
However, I suspect that they're only maintaining the WURFL fields that could be plausibly maintained independently of WURFL data: which means effectively deprecting a large part of the WURFL schema.
