Most DPP technical documents belong to one of these formats. Here is a simple guide to the purpose of each.
DPP Recommendation
A formal technical recommendation from the DPP, or a normative definition of specific technical parameters. Implementers of a DPP Recommendation are expected to implement it in full.
DPP Guidance
Supporting information, guidelines, or suggested implementation parameters. They are usually suggestions rather than requirements, and may be implemented in full or in part.
Versioning
We use simple version numbers for our documents, of the form:
majorVersion.minorVersion(.fixVersion)
The components are:
- majorVersion - a significant update, with major new functionality or changes. Backwards compatibility is always an aim, but is not guaranteed.
- minorVersion - a smaller update, with some new features or changes. Backwards compatible with all other minor versions of the same major version.
- fixVersion - a change that does not involve any technical change, and would not require any updates from implementers. May include things like fixing typos.
Partner Published Documents
In addition to DPP documents, some of our specifications are published in partnership with organisations such as:
