Open Standard for Mobile Health Data. This standard is composed of a number of related schemas. Widely-used clinical measures were identified and clinical experts were consulted to identify the most important distinctions for the schemas' clinical use. Use cases were then defined that included these measures in new models of care enabled by mHealth technology. While there isn’t one “correct” schema for any given measure, they aim to offer an ideal format and description of digital health data for supporting clinical and self care.
