This repository contains a set of related specifications for interoperability between different contest control systems and tooling that interact with it. These specifications have been designed and used in the contest of the ICPC Word Finals, and have also been used at various (sub)regionals; they are meant to be useful outside an ICPC context as well.

The following specifications are present:

• Contest Control System requirements for the ICPC World Finals
• Contest API: an API specification for accessing information provided by a CCS.
• Contest Archive Format: a format closely related to the Contest API for storing a contest on disk for archival.

There are multiple versions of the CCS specifications available on the documentation pages.

This is the draft of some future version of the CCS specification.
