The success of the project can be measured in immediate terms by semantic web traffic: the number of web site hits with an "Accept RDF" header, or the number of distinct users connecting to the SPARQL endpoint. In the longer term, the use of MusicBrainz URIs in third party tools and services,

We have identified a number of risks, which are listed with mitigation actions:
1) The MusicBrainz user community votes against the proposed changes
(Likelihood: Low; Impact: Medium)
