Six axes, none of them the category axis. Categories say what area an entry serves; these say what it works on, how it works, what can go wrong with it, and who it is for.

29 tags across 6 axes · 0 of 29 in use · 0 of 91 entries tagged

Every tag is reserved

The vocabulary is registered; none of it is in use. Each tag has a permanent address so it can be linked and cited now, and each will carry entries once the vocabulary goes into use. A tag turns active only when it can truthfully assert membership — the build fails if an active tag has no members, or a reserved one has any.

The axes are also served as JSON at /api/tags.json, with the emptiness stated field by field.

Artifact — what an entry works on

The material an entry reads or writes. Factual, and orthogonal to the category axis — one entry may work on two materials at once.

Method — how an entry works

The machinery an entry uses to do its job. Factual: it says how, and never how well.

Risk — what can go wrong

The failure mode to watch for when running an entry. An editorial axis, and the one we consider most load-bearing — none of it is in use yet, so no entry on this site has been inspected for risk.

Batch — publication cohorts

Publication cohorts — the freshness axis. Batch ids follow batch:yyyy-w##.

This axis is registered and has no tags yet. The first is minted when an entry first carries one.

The axes that are not tags

Two axes are stored fields on the record rather than tags, because each entry has exactly one value for them. They are linked here for one-stop discovery.

  • Category — the area an entry serves, with its denominated counts.
  • Status — live, archived, unavailable. An archived repository is still upstream; an unavailable one returned 404 when we retrieved, and its entry stays on the map with that date. See the standard.
