Extensions are declared in the top-level extensions array, and the ones a reader must support go in critical. The field reference lists every token, and the Extensions section covers each one.

Revisions above were current on datatracker on 2026-10-06. The datatracker links always open the newest revision.

Earlier drafts. The individual draft draft-petrie-vcon-04 used syntax "0.0.1". The later working group draft draft-ietf-vcon-vcon-container-03 used "0.0.2". Both are replaced by draft-ietf-vcon-vcon-core. Treat material citing them, or syntax 0.3.0, as historical.

Software

• vcon-dev/vcon gathers the project's repositories, including the conserver and libraries, as submodules.

• py-vcon is Dan Petrie's Python implementation, including py-vcon-server.

• This site documents the Python library, the JavaScript library and the Conserver.
