Byggdastofnun — Regional-development dashboards

Iceland's Regional Development Institute (Byggdastofnun, from byggdastofnun.is) publishes 11 Tableau-Public dashboards covering rural and regional statistics: population, income, property taxes, energy, state employment, grants, and the municipal-history map.

All 11 dashboards live on byggdastofnun.is/is/utgefid-efni/maelabord/<slug> and embed a viz from public.tableau.com/views/<workbook>/<view>.

All 11 Tableau workbooks are public (no auth, no token). They are cached content on Tableau Public's CDN and refresh when Byggdastofnun republishes.

Architecture

byggdastofnun.is is built on Moya CMS (Icelandic vendor). The index page .../maelabord lists each dashboard with an anchor; each sub-page embeds the Tableau view inside an <iframe>. This skill parses that pattern — one iframe per sub-page — to keep a catalog fresh.

For structured data extraction, Tableau Public does not expose a clean CSV path (?:format=csv returns HTML). The maskina skill documents the two-step VizQL startSession → bootstrapSession flow used to scrape structured poll data from a Tableau Public workbook; the same pattern applies here if/when a downstream task needs tabular access.

Usage

# Refresh the catalog from the live site (11 HTTP requests, ~5s)
uv run python scripts/byggdastofnun.py fetch

# Print the cached catalog
uv run python scripts/byggdastofnun.py list

# Get the Tableau embed URL for one slug — handy for shell pipelines
uv run python scripts/byggdastofnun.py url tekjur
# → https://public.tableau.com/views/tekjur/tekjur?:showVizHome=no&:embed=true

Catalog schema

data/processed/byggdastofnun_catalog.csv:

Column	Description
slug	Sub-page slug on byggdastofnun.is
title	H1 title from the live page
workbook	Tableau Public workbook identifier (from /views/<wb>/)
view	Tableau view within the workbook (specific dashboard tab)
embed_url	Full Tableau Public URL for direct embedding
page_url	Source page on byggdastofnun.is

Caveats

1. Catalog-only skill. Tabular data extraction would require implementing the VizQL flow (see maskina.md). Current scope is the URL/metadata catalog so a downstream consumer can pick the right workbook/view quickly.
2. Workbook name stability. Byggdastofnun has re-uploaded several workbooks in the past — the naming is inconsistent (note the mix of English + Icelandic + typo'd "Orkukostnaurheimila" without the ð). If a dashboard disappears, re-run fetch to pick up the new identifier.
3. Data sourcing. Most series are derived from Hagstofa PX-Web tables (hagstofan skill) plus additional Byggdastofnun surveys (ibuakonnun). For straight demographic and income work, prefer fetching raw PX-Web; Byggdastofnun's value is the regional cuts and the composite indices.
4. Mælaborð vs. publications. Byggdastofnun also publishes annual reports ("Byggðaþróunarskýrsla") and sector studies at byggdastofnun.is/is/utgefid-efni/skyrslur-og-rannsoknir. Those are PDFs and are out of scope for this skill; handle via a dedicated PDF extractor if needed.
5. Moya redirects. The landing page doesn't auto-redirect malformed slugs; url <slug> raises if the slug isn't in the catalog rather than guessing.
6. display_count parameter. Some pages use display_count=n (hidden visit counter), others display_count=y. The scraper preserves whatever the source iframe declares, so the embed URL is a faithful mirror.
7. Encoding. byggdastofnun.is HTML and the Tableau workbook identifiers are served as UTF-8. Note the typo'd workbook Orkukostnaurheimila (without ð) — preserve it verbatim in catalog output.
