Also note that nothing stops someone else from distributing binary models outside of Apache. Anyone who wanted to pick up the corpora and reach their own conclusion about the legitimacy of open distribution of binary models could build these models and distribute them via OSSRH to maven central. Just so long as they respect ASF trademark policies in describing the models as, oh, 'useful with the Apache OpenNLP software library'. > > James > > On 6/12/2012 12:37 PM, Michael Schmitz wrote: >> Hi James, is this the contract? >> >> http://trec.nist.gov/data/reuters/org_appl_reuters_v4.html >> >> If so, I think you are free to license your derived models however you >> please although you may not redistribute the training data. >> >> What models does the Reuters contract apply to? >> >> Peace.
