Business Sectors (Suites): Games and Interactive Media
Developed by: ScreenSkills
Approved on: 30 Mar 2021


​This standard is about using mark-up to develop content for games or interactive media projects. It involves selecting and using appropriate mark-up language, producing well-formed mark up and testing, debugging and documenting mark up for games or interactive media projects.

This standard can apply to games or interactive media. Interactive media can involve any type of interactive media content, products or services including, but not restricted to, websites, applications, or online marketing campaigns.

Games and interactive media projects can be for multi-platform or multi-channel use and can also involve the use of immersive technology which can include, but is not restricted to, Augmented Reality (AR), Virtual Reality (VR) and Mixed Reality (MR).

This standard is for anyone who uses mark-up to develop content for games or interactive media projects.
