260608 — Wiki engines overview (landscape scan)

Date: 2026-06-08

What this is

A breadth-first landscape scan of notable wiki engines — Wiki.js, XWiki, MediaWiki, Semantic MediaWiki, DokuWiki, TiddlyWiki, TWiki, Foswiki, Confluence, C2, Federated Wiki, Fossil — captured to understand the design space shard-wiki orchestrates over (and deliberately does not re-implement).

Complements the deeper-dive research:

• research/260608-c2-wiki-origins/ — pre-federation wiki culture
• research/260608-federation-concepts/ — Federated Wiki, git/AP federation models
• research/260608-yawex-prior-art/ — the specific Perl engine being superseded

Focus: what each engine is for, its storage/permission model, and what its existence implies for shard-wiki's adapter contract — not engine selection.

Contents

Path	Role
findings.md	Synthesis: storage/permission axes, shard-wiki mapping, adapter implications, open questions
260608-perplexity-wikiengines-research.md	Raw source dump (Perplexity), kept as provenance

Status

Initial scan complete. Reinforces the INTENT stance that shard-wiki is an orchestrator, not an engine: the heterogeneity below is the problem space, not a menu to pick from. Adapter-contract implications feed workplans/SHARD-WP-0002-federation-architecture.md.
