Following its established pattern, this year's Ontology Summit consists of a series of weekly virtual discussions, followed by a 2-day face-to-face symposium.
Each week a virtual meeting is held to discuss one of the topic tracks of the summit. Champions for that topic coordinate several speakers, and anyone interested may participate via telecon and a simultaneous text chat. Slides, audio recordings, and transcripts for previous meetings are available on the wiki pages linked below. For timely announcements and details of upcoming calls join the Ontology Summit mailing list and/or track the 2015 Ontology Summit Wiki.
