The International Symposium on Open Collaboration (OpenSym, formerly WikiSym) is an annual conference series dedicated to open collaboration research and practice.

OpenSym’s fiscal sponsor is the U.S.-based 501(c)3 tax exempt non-profit organization The John Ernest Foundation. Any donations to OpenSym are therefore tax deductible under U.S. tax law.

From the start of the conference series, the ACM has been a sponsor and supporter of OpenSym, and the conference proceedings are being archived in the ACM Digital Library as well as on this website.
