rekisteri

Register / registry (Finnish: rekisteri) manages catalogs of documents organised per publication identifier stem, issue, and optionally revision.

Requires Python 3.11 or later.

Install

pip install rekisteri

Manual

The man page provides the CLI reference (man rekisteri after placing the file on your MANPATH)

To use man rekisteri, copy docs/rekisteri.1 to a directory on your MANPATH, for example:

mkdir -p ~/.local/share/man/man1
cp docs/rekisteri.1 ~/.local/share/man/man1/

Overview

rekisteri is for operators of document publication registries — typically teams that publish structured document sets (specifications, guides, manuals) and need a stable, browsable web tree alongside a machine-readable catalog.

Given a rekisteri.yaml configuration it:

1. Scans a source/ref/ tree for documents organised by stem, issue, and (optionally) revision.
2. Validates the tree: checks metadata completeness, issue numbering consistency, slug uniqueness, and catalog cross-references.
3. Publishes a web-parent/ tree:
   • ref/ — anchor copies of all documents with index navigation symlinks at issue and stem level.
   • pub/ — per-slug cross-reference symlinks into ref/, grouped by issue.
   • reference → ref and publication → pub alias symlinks at the root.
4. Generates catalog JSON files (documents.json, cards.json) at a separate catalog-out path for consumption by a side-loading web application.

Source tree structure

Two-level (levels: 2, default)

source/ref/
└── <STEM>/
    ├── publication.yaml     ← stem-level metadata (title, status, …)
    ├── <ISSUE>/
    │   ├── issue.yaml       ← optional issue-level metadata overrides
    │   └── <stem>-<some_id>-<issue>.<ext>
    └── <ISSUE>/
        └── …

Three-level (levels: 3)

source/ref/
└── <STEM>/
    ├── publication.yaml
    └── <ISSUE>/
        ├── issue.yaml
        └── <REVISION>/
            ├── revision.yaml    ← optional revision-level metadata overrides
            └── <stem>-<some_id>-<issue>.<ext>

Issue directories contain only digits (01, 2, …). Revision directories are any non-numeric non-hidden name (A, B, draft, …).

Quickstart

# Write rekisteri.yaml and publication.yaml templates into the current directory
rekisteri eject .

# Check the tree is well-formed
rekisteri validate --config rekisteri.yaml

# Show the discovered publication tree
rekisteri explain

# Publish the web-parent tree
rekisteri publish

Configuration

rekisteri.yaml controls all paths and behaviour. Run rekisteri eject to write a commented template.

source-root: ./source/ref    # path to the source document tree
web-root: ./web-parent       # path where the published tree is written
catalog-out: ./catalog       # path where catalog JSON files are written
levels: 2                    # 2 (stem/issue) or 3 (stem/issue/revision)
# stem-pattern: null         # optional regex; only matching stems are scanned
# slug-pattern: null         # optional regex applied to some_id before slugifying
catalog:
  documents-file: documents.json
  cards-file: cards.json
  cards:
    - title: Guides          # display name for this card group
      identifiers: [INTRO]   # slugs of publications belonging to this group

All multi-word keys are kebab-case. --config / -c accepts either a file path or a directory (looks for rekisteri.yaml inside it).

Metadata files

Each stem, issue, and revision may carry a YAML metadata file. Inner files override outer ones via dict.update(); keys the inner file does not mention are inherited unchanged.

title: ""          # human-readable publication title (required; must not be empty)
abstract: ""       # short abstract
responsible: ""    # team or person responsible
tags: []           # free-form tags
status: active     # active | superseded | archived
supersedes: []     # list of STEM/ISSUE entries this publication supersedes
mapping: []        # list of mapping slugs from mapping.yaml (used by rekisteri map)

Filename conventions

Documents are named <stem>-<some_id>-<issue>.<ext>, all lowercase. The some_id part is extracted by stripping the stem prefix and the issue suffix from the filename stem. It is then uppercased (after optional slug-pattern filtering) to form the slug used in pub/ and catalog.

Example: x-guide-intro-01.pdf in stem X-GUIDE, issue 01 → some_id = intro → slug = INTRO.

The slug is stable as long as some_id is preserved across stem renames and issue increments.

Web-parent tree topology

After rekisteri publish:

web-parent/
├── ref/
│   └── <STEM>/
│       ├── index.<ext>              → latest issue's document
│       └── <ISSUE>/
│           ├── <doc-name>.<ext>     ← anchor copy
│           └── index.<ext>          → <doc-name>
├── pub/
│   └── <SLUG>/
│       ├── index.<ext>              → latest issue's document
│       └── <ISSUE>/
│           ├── <doc-name>.<ext>     → ../../../ref/STEM/ISSUE/doc
│           └── index.<ext>          → <doc-name>
├── reference                        → ref
└── publication                      → pub

With --copy, pub/ entries are real file copies instead of symlinks (useful for Windows or archival scenarios).

Commands

rekisteri doctor

Check the environment and configuration: Python version, config file presence, source-root existence, and web-root parent.

rekisteri doctor [-c PATH]

rekisteri eject

Write rekisteri.yaml and publication.yaml templates to a target directory. Skips existing files unless --overwrite is given.

rekisteri eject [TARGET] [--overwrite]

rekisteri explain

Print the discovered publication tree: stems, issues (and revisions for three-level trees), documents, and slugs.

rekisteri explain [-c PATH]

rekisteri publish

Build the web-parent/ tree from the source tree. Creates anchor copies in ref/, cross-reference symlinks in pub/, and the reference / publication alias symlinks.

rekisteri publish [-c PATH] [--copy]

--copy replaces pub/ cross-reference symlinks with real file copies.

rekisteri validate

Validate the source tree and metadata. Prints findings tagged [error] or [warning]. Exits 1 on any error; with --strict, also exits 1 on warnings.

rekisteri validate [-c PATH] [--strict]

rekisteri map

Harvest the latest active issue per stem, group documents by mapping slug, and write mapping.json to catalog-out. Requires mapping-source to be set in rekisteri.yaml pointing to a mapping.yaml file. publish runs this automatically when mapping-source is configured.

rekisteri map [-c PATH]
