Doxa Maps 60e5fdcf42 The map learned to name peoples, not just their languages
?codes= filters by LANGUAGE, which is what a partner's list usually is and the wrong
filter for a list of peoples. The reach table measured the gap in its own rows: its
Mandarin row counts 36 groups, those 36 speak 30 codes, and 55 Doxa groups speak those
30 — so a link from a 36-group row drew 55 pins. Akha's 33 drew 57; SUN's 93 drew 116.
The extra groups are real and also have nothing; they belong to a different row.

So the map takes ?groups=<slug list> and filters by people group. The slug is
doxa.life's own — carried from the roster into the pin rows, and read in the builder
off the prayer URL their API built from it, never constructed from a name, because a
slug this build invented could name somebody else's people. All 369 of those rows
carry a prayer URL, measured before relying on it.

Row and map now agree by construction: 0 of 35 rows disagree, and the Mandarin link
renders "36 / 2,107" on the map against a row claiming 36. The gate asserts exact
equality for a three-slug link and 0 for an unknown slug — the failure that would
quietly turn a partner's 40-group embed into the whole roster.

The longest link is 1,577 characters, SUN's 93 slugs; well inside what browsers carry,
but worth knowing before anyone adds a row with a thousand groups.

Embedding the gospel-resources map

The map's URL is its interface. A partner embeds one address in an iframe and never touches it again, so every parameter below is a promise kept by a gate (bun run check:embed-contract), not a convention.

<iframe src="https://<host>/dx-maps/gospel-resources/resources-map/index.html?codes=kfr,cmn,npi"
        style="width:100%;height:600px;border:0" title="Gospel access"></iframe>

The six addresses

Address What the reader gets
?codes=<iso3,iso3,…> Only those languages' people groups, framed on them. Shows 74 / 2,107, and that count is the button back to the whole map.
?groups=<slug,slug,…> Exactly those people groups, by doxa.life's own slug, framed on them. Use this when your list is peoples rather than languages: a language filter shows every group speaking it, which for one bridge language was 55 pins against a list of 36.
?country=<ISO3> That country's sheet open, framed on its groups. The country's own name also works (?country=India).
?code=<iso3> The people group's sheet, with its resources. &name= and &country= disambiguate when a language has many groups.
?view=zero The groups with nothing found — the question this map exists for. ?view=gap is the same view.
?tab=province&province=<name> On the data tables: that state's row — groups, people, what has nothing, the local way in, and who nobody is praying for. Accents are folded, so Arunachal Pradesh finds Arunāchal Pradesh.

?provider=maplibre is not this map's parameter but the whole fleet's: it selects the keyless engine, and no map ever substitutes a different one (bun run check:engine-contract).

Bring your own list

The join is ISO 639-3, the key every resource in this map is already joined on. A partner's list needs no agreement with Doxa's roster — only the codes their own data carries. That is the point: this corpus is public so that other lists can stand on it.

Two things to know before you publish a link:

  • The denominator is Doxa's roster. The research corpus holds 12,379 people groups; this map draws the 2,107 Doxa works, so ?codes= intersects with those. A code outside the roster draws nothing.
  • It filters, it never invents. A link matching none of its codes shows an empty map reading 0 / 2,107. That is the truth about the link — showing the full map instead would tell you your broken list works.

What the map does not promise

  • No zoom or centre parameter. The frame is derived from the pins the link selects, so a link stays correct when the data moves under it.
  • Placement is approximate. A dot marks where a people is found, not a town or a boundary, and 108 of the placed groups share a coordinate with another group. The sheet says so in the reader's language.
  • An unknown parameter is ignored, never fatal. ?country=ZZZ renders the map, not an error — a partner's typo must not break their page.
