Deep dive into XWiki past the landscape scan: component/DI architecture, document + class/object data model, oldcore, Hibernate storage + xwikircs history, ObservationManager events, rendering pipeline, multi-wiki; the full extension-interface surface (components, Java/wiki macros, script services, UIX/UIXP, JAX-RS REST, event listeners, resource handlers); and the extensions.xwiki.org ecosystem (XAR/JAR/WebJar, 900+ extensions). Catalog: - UC-38 make a wiki engine federation-capable via its native extension API (composable integration — first engine-side-direction UC; XWiki is proof) - UC-39 attach a wiki-as-application-platform shard (bodiless typed pages) - enrich UC-31 (ObservationManager event-driven sync), UC-34 (XObject model), UC-36 (xwikircs internal history) with concrete XWiki specifics Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# 260613 — XWiki deep dive (implementation, extension interfaces, ecosystem)
|
|
|
|
Date: 2026-06-13
|
|
|
|
## What this is
|
|
|
|
A focused study of **XWiki** — the canonical "wiki-as-application-platform"
|
|
engine flagged in `research/260608-wikiengines-overview/`. Goes past the landscape
|
|
scan into XWiki's **implementation** (component/DI architecture, document data
|
|
model, storage, rendering, events), the **interfaces it exposes to extend the core
|
|
engine** (components, macros, UI extension points, script services, REST), and the
|
|
**extension ecosystem** (extensions.xwiki.org repository, XAR/JAR/WebJar types,
|
|
notable extensions).
|
|
|
|
Read through one lens: **what does XWiki teach shard-wiki about (a) adapting a
|
|
structured app-platform engine as a shard, and (b) how a host engine can become
|
|
federation-capable through its own extension mechanism** (INTENT *composable
|
|
integration*).
|
|
|
|
Complements:
|
|
- `research/260608-wikiengines-overview/` — the landscape scan that surfaced XWiki
|
|
- `research/260608-federation-concepts/` — already covered XWiki's ActivityPub extension

## Status
|
|
|
|
Initial deep dive complete. Two new use cases promoted to
|
|
`spec/UseCaseCatalog.md` (UC-38, UC-39); existing UC-34/UC-36/UC-31 enriched with
|
|
XWiki specifics. Adapter-contract implications feed
|
|
`workplans/SHARD-WP-0002-federation-architecture.md`.
