The OSLC Communications UG has a handy table of the upcoming conferences that feature OSLC content, delivered by OSLC community members, throughout the rest of this year.
The list includes the previously mentioned presentations at the OMG Technical Meeting and JavaOne conference, as well as events in Europe such as the Rational User Conference and the Artemis/ITEA2 conference, both in Sweden.
Be sure to check out the full list, and to let us know if there are other events that should be added. (Or if you already know of events in 2014 that would cause us to start a new list too.)
