imin Extension Namespace Vocabulary Terms

This repository holds the JSON-LD definition of the imin namespace. The terms in this namespace are defined for use within the imin Search API, and are not designed to be used by data publishers. Data publishers should consider publishing thier own extension namespace or using the OpenActive Beta Namespace.

imin works as part of the OpenActive Community Group to promote the usecases represented by the properties within this namespace, with the intention of standardising them over time.

This namespace MUST be referenced using the URL "https://imin.co/" (which will return the JSON-LD definition if the Accept header contains application/ld+json), and is designed to be used in conjunction with the "https://openactive.io/" namespace.

Please raise requests for content or issues related to the namespace via GitHub.
