regmeta 0.5.2

Search and query SCB registry metadata

regmeta

Search and query SCB registry metadata from a local SQLite database. Designed for programmatic use by LLM agents and tools; terminal use is secondary.

Install

uv tool install regmeta
regmeta maintain update      # downloads package + database (~400 MB compressed)

Alternatively, build from raw SCB CSV exports (requires access to mikrometadata.scb.se):

regmeta maintain build-db --csv-dir path/to/SCB-data/

Quick start

regmeta search --query "kommun"                     # search all fields
regmeta search --query "kommun" --field datacolumn  # column headers only
regmeta get register LISA                           # register overview
regmeta get schema --register LISA --years 2020     # columns for a year
regmeta get varinfo "Kön"                           # variable details
regmeta resolve --columns "Kon,FodelseAr"           # map column names
regmeta docs search "disponibel inkomst"            # search documentation
