Document Header for libp2p Specs

A standard document header to indicate spec maturity, status & ownership.

Lifecycle Stage Maturity Status Latest Revision
1A Working Draft Active r0, 2019-05-28

Authors: @yusefnapora

Interest Group: @raulk, @vyzo, @mgoelzer, @jacobheun, @tomaka

See the lifecycle document for context about the maturity level and spec status.

Motivation

The maturity and lifecycle spec defines levels of maturity for libp2p specs, as well as the states that a spec can be in at a given time. It also introduces the notion of an Interest Group, which is a set of libp2p community members that have expressed interest in the spec and are willing to help move it forward in its evolution.

This document defines a header format to convey this key status information in an easy-to-read manner.

Example

# Spec title

> An optional one-liner summary of the spec

| Lifecycle Stage | Maturity                 | Status | Latest Revision |
|-----------------|--------------------------|--------|-----------------|
| 2A              | Candidate Recommendation | Active | r0, 2019-05-27  |


Authors: [@author1], [@author2]

Interest Group: [@interested1], [@interested2]

[@author1]: https://github.com/author1
[@author2]: https://github.com/author2
[@interested1]: https://github.com/interested1
[@interested2]: https://github.com/interested2

See the [lifecycle document][lifecycle-spec] for context about the maturity level
and spec status.

Format

Title and Short Intro

Each spec begins with its title, formatted as an H1 markdown header.

The title can optionally be followed by a short block-quote introducing the spec, which serves as a subtitle and should be a maximum of one or two lines.

Status Table

The main status information is contained in a markdown table, using the table syntax supported by Github Flavored Markdown.

The status table consists of a single row, with a header containing the field names.

Example:

| Lifecycle Stage | Maturity      | Status | Latest Revision |
|-----------------|---------------|--------|-----------------|
| 1A              | Working Draft | Active | r0, 2019-05-27  |

The following fields are all required:

  • Lifecycle Stage
  • Maturity
    • The full name of the maturity level that the spec is currently in.
    • Valid values are: Working Draft, Candidate Recommendation, Recommendation.
  • Status
    • The full name of the status that the spec is currently in.
    • For Candidate Recommendation or Recommendation specs, valid values are Active and Deprecated.
    • For Working Draft specs, valid values are: Active and Terminated.
  • Latest Revision
    • A revision number and date to indicate when the spec was last modified, separated by a comma.
    • Revision numbers start with lowercase r followed by an integer, which gets bumped whenever the spec is modified by merging a new PR.
    • Revision numbers start at r0 when the spec is first merged.
    • Dates are formatted according to ISO 8601.

Authors and Interest Group

After the status table, spec Authors and Interest Group members are listed.

Authors and Interest Group members are referenced by their Github handles (with a leading @ symbol), and are presented as a comma-separated list of links to Github profiles.

To make the list readable in the markdown source, we use the shortcut reference link syntax, which allows us to wrap the author name in square brackets in the list and define the link target below. Albeit this may appear redundant when viewing in github.com with the GitHub renderer, it's necessary to avoid losing information when viewing elsewhere.

For example:

Authors: [@author1], [@author2]

Interest Group: [@interested1], [@interested2]

[@author1]: https://github.com/author1
[@author2]: https://github.com/author2
[@interested1]: https://github.com/interested1
[@interested2]: https://github.com/interested2

The Authors and Interest Group lists must be separated by a newline, which causes them to render as distinct paragraphs.

When proposing a new Working Draft where the Interest Group is unknown, use TBD to indicate that the group is To Be Determined:

Interest Group: TBD

Link to Lifecycle Doc

Finally, the header should contain a link to the lifecycle spec so that readers can get up to speed on the definitions used in the header. To avoid having to keep track of relative paths within the specs repo, an absolute URL is preferred when linking to the specs document.

Here's an example that can be copy/pasted directly:
