Many discussions on the mailing list, inside JWT as well as with partners from the SOA projects (Mangrove, BPMN, BPMN2, Stardust etc.).
Discussions with several companies (Bull, jBoss, EasiFab) have produced collaboration (ex. BPM model comparison, FactoryRegistry) and keep feeding JWT‘s requirements.
Solutions built on JWT include AgilPro and OW2 Scarbo (Open Source). Mailing list exchanges show new products being built on JWT.
The friend EasySOA community (http://www.easysoa.org) has worked in 2011-2013 on using JWT to design and model the business part of an SOA such as the EasySOA Registry models. This has produced the (not yet released) EMF2CMIS bridge to document management solutions.
Coordination with several OW2 projects such as Nuxeo, Talend, Bonita, Orchestra, FraSCAti, Spagic, Scarbo.
