reg-meta 0.22.0

Search and query SCB registry metadata

reg_meta

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 reg-meta
reg-meta update      # downloads package + database (~400 MB compressed)

Alternatively, build from raw SCB CSV exports (maintainer flow — requires access to mikrometadata.scb.se and a repo checkout, since build-db reads classifications.toml, fqid_slugs/, and input_data/SCB/ from the working tree; none of those ship in the wheel):

git clone https://github.com/adamaltmejd/registry-research-toolkit
cd registry-research-toolkit
uv sync
uv run reg-meta-build build-db --input-dir reg_meta_build/input_data/

Quick start

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

Use --help on any command or subcommand for full flag documentation.

Commands

Query

Command	Purpose
search	Free-text search across registers, variables, columns, and value codes
get register	Register overview with variants
get schema	Column listing per register edition (validity window), with --years, --columns-like, --summary, --flat
get groups	Concept groups (folded variable families) with member facets; --classifications for vintage families
get varinfo	Variable details with per-era variable_state history
get values	Value-set members for a variable, year-projected per variable_state era
get datacolumns	All column aliases for a variable across registers
get coded-variables	Variables with value sets, ranked by usage
get diff	Schema changes between two years for a register
get lineage	Variable provenance across registers
get availability	Temporal coverage for a variable or register
get classification	Normalized code systems (SUN, SSYK, SNI, LKF, ...) with --list, --codes, --variables
resolve	Exact alias lookup for column names (batch)

Documentation

Command	Purpose
docs search	Full-text search over curated register documentation
docs get	Retrieve full documentation for a variable or topic
docs list	Browse available documentation by type, topic, or register

Maintenance

Command	Purpose
update	Update package and database to the latest version
info	Database stats and import metadata

Build commands (build-db, build-docs, seed-slugs, precheck-slugs, parse-sos) live in the separate reg_meta_build package. They are maintainer-only and require a repo checkout (the wheel does not ship classifications.toml, fqid_slugs/, or docs/); see the reg_meta_build README for the build flow.

Output formats

All commands support --format {table,list,json}. Default is table, which auto-switches to list for narrow results. Add -v for the full JSON envelope (contract version, timing, database info).

Register arguments accept numeric IDs, exact names, or substring matches.

Database

Stored at ~/.local/share/reg_meta/ by default. Override with --db or $REG_META_DB.
