Guiding Principles

Our guiding principles for making design choices.

This specification was created and will be maintained by following these main principles:

  • Open Standard:

    • No Intentional Secrets: The standard does NOT withhold any detail necessary for interoperable implementation. As flaws are inevitable, the standard will fix flaws identified during implementation and interoperability testing and to incorporate said changes into a revised version or superseding version of the standard to be released under terms that do not violate the open standard requirement.

    • Availability: The standard is freely and publicly available under royalty-free and patent-free terms.

    • No Agreements: There is no license agreements, NDA, grant, click-through or any other form of paper to deploy conforming implementations of the standard.

    • Interoperable: Implementation and consumption of the standard does not require any non open standard technology.

  • Lossless:

    • The standard should allow for no loss of data from the real-time events from the user's perspective. The user's perspective should be completely replayable via the user at any point in time after the hand has completed.

  • Efficient:

    • The standard should be as efficient as possible without sacrificing data loss and portability. However, due to cheap storage, efficiency should always be the last guiding principle.
