Version 4 isn't taking any more features in, so this page exists to hold any and all suggestions for the next version.

This is not a list of features that are expected to be in a future version. It's a place to put these ideas until version 4 is out the door, to come back to and think about later.

General

  • Schema templating (discussion)
  • Internationalisation (specifying language of current resource, linked resources)
  • Accessibility (what issues might there be?)
  • "Informative" keywords (a bit like format - non-validation, but informative for processing) (issue)
  • patternGroups - replaces patternProperties, enabling min/max, etc.

Validation features

  • Schema merging (e.g. extending "enum" options, overriding "additionalProperties", etc)
  • Storage-specific number types (e.g. uint32, long, byte) - define as "type" or "format"?

Hyper-schema/-media features

  • Separate map for template variables (more flexibility, including JSON Pointer support)
  • Templating of "rel", "mediaType" or others (possible syntax: {"rel": {"template": "{relVar}"}}) - would allow fully-functional meta-schema for link format, as well as allowing us to fully describe other linking formats such as HAL.
  • "invalidates" keyword in LDOs
