Contest Control System specifications

This repository contains a set of related specifications for interoperability between different contest control systems and tooling that interacts with it. These specifications have been designed and used in the contest of the ICPC World 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.

Furthermore, a tool and JSON schema specifications are available to validate an implementation of the Contest API. Run check-api.sh -h from the root of the repository for usage information.

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.
