JW Convention Program – Obsidian Plugin

An Obsidian community plugin that imports official convention program files of Jehovah's Witnesses and turns them into structured, linked Markdown notes in your vault.

Language note: The plugin supports German, English, French, Italian, Portuguese, Russian and Spanish program files. Generated notes automatically follow the language of the imported file — a German jwpub file produces German notes, a French one French notes, and so on. The plugin interface itself (settings, import dialog, Bible-verse popup) can independently be switched between all seven languages.

Features

• Supported convention types
  • CO – Regional Convention (Friday / Saturday / Sunday)
  • CA-copgm – Circuit Assembly With Circuit Overseer (one day)
  • CA-brpgm – Circuit Assembly With Branch Representative (one day)
• Supported languages: German, English, French, Italian, Portuguese, Russian and Spanish – the language of the program file is detected automatically (via its MepsLanguageIndex), and all generated notes, labels, file and folder names follow it. The plugin's own interface (settings, import dialog, Bible-verse popup) can independently be set to any of the same seven languages.
• Primary source: .jwpub – full decryption (AES-128-CBC + zlib) and HTML parsing
• Fallback: RTF-ZIP – used automatically when no jwpub is available (German exports only)
• One folder per convention, named after type, year/season and theme – created directly in the vault root by default, without an extra wrapper folder
  • Regional conventions additionally get one subfolder per day
  • Circuit assemblies (one day) place their notes directly in the convention folder
• One note per program item, numbered in program order (01., 02., …)
  • Symposiums get one note with a heading per part
• A per-day overview note (00. Overview.md; 00. Übersicht.md for German imports) with the complete day's program:
  • the day's cover image and theme (with linked scripture) at the top
  • every program item linked to its note
  • symposium parts linked straight to the matching section
  • scriptures linked inline
  • songs shown with a JW Library deep link (no dedicated note)
  • breaks and music videos shown as plain entries (no dedicated note)
• Back link to the day's overview at the top of every program-item note
• "Next:" hint at the end of every note – the following song (linked), the next program item (linked to its note) or the break
• Clickable scriptures as JW Library deep links in every note
• Bible-verse popup (optional): with a user-supplied Bible jwpub file (nwt/nwtsty), clicking a scripture opens the verse text directly in Obsidian – including footnotes, cross-references and study notes – instead of jumping to JW Library. A button in the popup can also insert the shown passage as a quote into the note last focused before the popup opened. An inserted quote is itself clickable (the whole callout, not just its title) and reopens the popup; opened that way, the popup offers a "Remove quote" button instead of "Insert as quote", since re-inserting the very quote already shown would just create a redundant copy.
• Optional YAML frontmatter (stable English keys, e.g. for Dataview queries) can be added to every generated note – off by default, notes stay frontmatter-free otherwise.
• Type a scripture reference anywhere, in any note (e.g. Psalm 12:1, or an abbreviation like Matth. 5:2) and a suggestion pops up right after typing it, offering up to four actions – both fully offline, using the loaded Bible file: link it, link it and open JW Library immediately, insert the verse text as a quote (replacing the typed reference), or insert the quote while turning the reference into a link instead. Each of the four can be individually enabled/disabled and freely reordered in the settings.
• Review note (Review.md; Wiederholung.md for German imports) with the three standard reflection questions for the congregation's convention review
• Printed review questions ("Find Answers to These Questions") become their own note with one heading per question, always numbered last
• Meeting Workbook ("Leben und Dienst") import — German only, new: imports the Life-and-Ministry-Meeting-Workbook .jwpub file as one note per week (not one per assignment) — the three fixed sections, every numbered item with its actual descriptive text from the workbook (not just a metadata summary), the ministry-assignment label bolded in place, duration, discussion questions (with any embedded scripture reference kept clickable), the opening/mid-week/closing songs, and the always-last Congregation Bible Study. Every source-material citation (e.g. "th"/"Werde ein besserer Leser und Lehrer", "lmd"/"Liebt Menschen, macht sie zu Jüngern") links to its real jw.org/finder page, exactly like songs already do. Each week's own cover image is embedded at the top of its note, and notes are numbered chronologically (01., 02., …) so the file explorer's default sort matches the actual week order. A "Bibelleseprogramm für das Gedächtnismahl" insert (appears in the Memorial-season issue) gets its own per-day reading checklist note. Has its own import/update commands, ribbon icon and settings section, fully independent of the convention-program feature above.

Tip: pairs well with JW Library Linker

The JW Library Linker plugin lets you turn scriptures you type yourself (anywhere in your vault, not just in imported convention notes) into clickable jwlibrary:// links. Both plugins use the same link format, so once you've loaded a Bible file here, clicking a Library-Linker-created link also opens this plugin's offline verse popup — you get typed-reference linking from one plugin and the in-app verse popup from the other, together.

Requirements

• Obsidian ≥ 1.6.6
• Runs on desktop and mobile (iOS/Android) – decryption uses WebCrypto (crypto.subtle) instead of Node crypto, pako instead of Node zlib, fflate instead of adm-zip

Installation

Manual (development / testing)

1. Clone or download the repository
2. npm install in the project folder
3. npm run build (once) or npm run dev (watch mode)
4. Copy main.js, manifest.json and styles.css into the vault's plugin folder:

   <Vault>/.obsidian/plugins/jw-congregation-program/
   

5. Reload Obsidian → Settings → Community plugins → enable the plugin

Community plugin store

Not published yet – currently in review.

Usage

1. Ribbon icon (book symbol), command palette or the "Import & update convention programs" section at the top of the plugin's settings → "Import convention program"
2. Pick a program file (.jwpub or RTF-ZIP)
3. Pick a target folder (vault root is the default; an existing folder or "new folder" can be chosen instead)
4. Check the preview (convention type, theme, detected days/program items)
5. Import – the convention folder with all notes is created

Re-importing into an existing convention folder only refreshes purely derived files (overview, cover image). Notes with your own entries (speaker, personal notes) are never overwritten.

Updating notes after a plugin fix

If a plugin update fixes a bug in the generated notes themselves (e.g. a wrong weekday or a broken scripture link), you don't have to delete anything to pick it up. Command palette → "Update convention notes" (also reachable from the same settings-tab section as import) re-parses the same program file and patches an already-imported convention folder in place: every automatically generated field (day, time, scripture links, headings, the "Anschließend"/"Next" hint) is refreshed, while anything you typed yourself — speaker name, personal notes — is left completely untouched, even in the very same note.

This works because every generated note carries invisible markers around each derived field (empty <span> elements hidden by this plugin's own stylesheet, never shown in Reading View or Live Preview). Only notes created by this plugin version or later have them — older notes fall back to being left alone, reported separately in the result notice.

Correcting even older, marker-free notes

Notes created before version 1.9.0 predate the marker mechanism entirely, so the merge above has nothing to anchor to. For those, "Update convention notes" falls back to a second, more conservative check: it looks for a small set of fields that are always written as one complete, uniquely labelled line — Day, Time, Scriptures, and the "Anschließend"/"Next" hint (never the Speaker field, which the plugin never fills in to begin with). A correction is proposed only when that label's line appears exactly once in both the existing note and the freshly parsed one and its value actually changed; if the label is missing, or appears more than once (e.g. a symposium note with a separate scripture line per part), that field is silently left alone rather than guessed at.

Nothing from this is ever written automatically. When such notes are found, a second, distinct notice appears after the update finishes — clicking it opens a review window listing every proposed change (old value → new value) grouped by note, each with its own on/off switch. Only notes left switched on are patched, and only after clicking "Apply".

Meeting Workbook ("Leben und Dienst") import

A second, independent ribbon icon (calendar symbol), command palette entry, or the "Import & update Meeting Workbook" settings section imports a Life-and-Ministry-Meeting-Workbook .jwpub file the same way — pick the file, pick a target folder, check the preview, Import. One folder per issue is created, with one Markdown note per week (not one per assignment, unlike the convention feature above — a week's schedule is meant to be read as a whole). "Update Meeting Workbook notes" re-parses the same file and patches an already-imported issue folder in place, exactly like "Update convention notes" does, via the same invisible-marker mechanism — every numbered item keeps its own marker (the Congregation Bible Study gets a dedicated one), so anything typed underneath it is preserved.

Currently supports German workbook files only — the three section headings and the Congregation-Bible-Study title double as both display text and parser detection anchors, and only German real files have been verified so far. Picking a file in another language, or a convention-program file by mistake, is rejected with a clear message rather than silently misparsed.

Settings

The very top of the tab, "Import & update convention programs", explains the difference between the two functions described above and offers an "Open" button for each — so both are discoverable without knowing the ribbon icon or command palette.

Setting	Default	Description
Target folder	(vault root)	Parent folder for new convention folders (overridable per import); empty = no wrapper folder
Language of the interface and Bible-verse popup	Deutsch	Plugin labels and Bible book names in the popup, selectable from all 7 supported languages independently of any note's own language. Generated notes follow the imported file's language automatically
Create review note	on	Creates the additional review note
Note fields	all on	Show/hide the Day/Time/Scriptures/Speaker fields individually, plus free-form extra fields
Add frontmatter (properties)	off	Adds YAML frontmatter with stable English keys (convention, type, day, time) to every generated note, independent of the note's own language – e.g. for Dataview queries

All settings around scriptures — linking, the click/tap popup and the as-you-type suggester — live together under one "Scripture references" heading:

Setting	Default	Description
Link scriptures	on	Generates clickable jwlibrary:// links
Enable Bible-verse popup	on	Whether clicking/tapping a scripture opens the in-app popup at all — independent of whether a Bible file is loaded, so the popup can be switched off without removing a large file
Bible file	–	Optional Bible jwpub file for the verse popup (study edition nwtsty for study notes; the much smaller regular edition nwt is the memory-friendly choice on mobile)
Typed scripture suggestions	all on, default order	Enable/disable and reorder the four actions offered when typing a scripture reference (link, link & open JW Library, insert as quote, insert as quote & keep the link)

A separate "Import & update Meeting Workbook" section (with its own "Meeting-Workbook note fields" group) holds the Leben-und-Dienst-specific settings — target folder, scripture linking, show/hide duration and source-citation fields, and frontmatter — fully independent of the settings above, since the two note types are conceptually different content.

Folder & note structure

By default (target folder = vault root), each convention is its own top-level folder:

2026 Regional Convention – Eternal Happiness/
  Friday/
    Cover.jpg
    00. Overview.md
    01. Abundant Happiness Forever—Is It Realistic？.md
    ...
  Saturday/
  Sunday/
  Review.md
2026-2027 Circuit Assembly – With Circuit Overseer – “Theme”/
  Cover.jpg
  00. Overview.md
  01. Why Trust In Jehovah With All Your Heart.md
  ...
  10. Find Answers to These Questions.md   ← always numbered last
  Review.md

(Examples show English imports; a German program file produces German names throughout — e.g. Regionaler Kongress 2026 – …, 00. Übersicht.md, Titelbild.jpg, Wiederholung.md.)

A Meeting Workbook issue is its own top-level folder too, with one numbered note per week (German only, so always German names):

Leben und Dienst 2026 Jan⁄Feb/
  01. 5.-11. JANUAR.md
  01. Titelbild.jpg
  02. 12.-18. JANUAR.md
  02. Titelbild.jpg
  ...
  Bibelleseprogramm für das Gedächtnismahl 2026.md   ← only in the Memorial-season issue

Technical details

• Decryption: sha256(cardString) XOR constant → AES-128-CBC key + IV, via crypto.subtle (WebCrypto) – identical on desktop and mobile
• Decompression: pako (pure JS, compatible with Node zlib's inflate)
• ZIP handling: fflate (pure JS)
• sql.js runs with an embedded WASM binary: the .wasm file is embedded into main.js as base64 at build time (esbuild binary loader) – no network access, no separate file
• Parsing strategy: DOMParser over the decrypted HTML content
• Language detection: Publication.MepsLanguageIndex (0 = English, 1 = Spanish, 2 = German, 3 = French, 4 = Italian, 207 = Russian, 785 = Portuguese); parsing patterns (session headings, type markers such as SYMPOSIUM:/VORTRAGSREIHE:/SIMPOSIO:, music/break lines) accept all seven languages
• Scriptures: taken directly from <a href="jwpub://b/NWTR/..."> links in the HTML
• Songs: recognized via <a href="jwpub://p/…"> links without an accompanying Bible link; the real jw.org docid is read from that very href (never computed – the docid is not a linear function of the song number)
• Cover images: resolved per day document via the Multimedia/DocumentMultimedia tables (CategoryType 8)
• Filenames: characters forbidden on Windows (? " : / \ | * < >) are replaced with visually similar Unicode look-alikes instead of being dropped
• No network requests – processes only local user files
• No copyrighted material in the repository
