An exhibition of Petri net tools will take place on Thursday. It consists of informal demonstrations for small groups/individuals, and there are no scheduled talks. Requests for participation in the tool exhibition must be sent to the Tool Exhibition Chair, Dr. Unai Arronategui (firstname.lastname@example.org), before June 1, 2017. They should include a link to the web pages for the tool (or a short description of the tool). The demonstrators bring their own machines, while the organizers may be requested to give access to the Internet.
