The DeadlineAPI project provides a list of URLs (the Directory) of endpoints which implement the DeadlineAPI Schema. This can be universities maintaining endpoints or conferences doing this on their own.
The directory is a curated list of endpoints, each providing a JSON file based on the Schema. In order to provide deadlines of your conferences on your own you need to run an endpoint and add your endpoint to the directory. This can be done via a pull request on Github. The directory is provided statically here: directory.json. Another option is to add your deadlines to an already existing endpoint. E.g., we run one here. Currently the endpoint is under mainenance, though.
The schema is a standardized JSON file format that can be used to present deadlines for conferences and workshops, especially academic but also other conferences. The specification uses JSON Schema. Due to this easy format every imaginable format can be bridged easily and be provided as an endpoint.
The following example shows how such an endpoint can look like (incl. some optional fields). A full documentation of all fields, though, can be found in the documentation.
