Evaluated modelling a wiki information space as a zzstructure: a page is a cell at the intersection of many co-equal dimensions (namespace tree, created-from genealogy, version, shard, equivalence, links). Recommendation: adopt zzstructure as a navigation/visualization/indexing LENS (a derived dimensional projection over the union), not as the storage substrate — Git and sovereign shards stay canonical, and the many-to-many link graph does not fit the one-neighbour-per-dimension rank rule. Clone <-> transclusion convergence with the Xanadu dive. Added UC-47/48/49; enriched UC-05/22/26/29; dimensional projection layer + genealogy-edges-in-journal logged as architecture for SHARD-WP-0002. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
260614 — ZigZag / zzstructure deep dive (an information space as orthogonal dimensions)
Date: 2026-06-14
What this is
A focused study of Ted Nelson's ZigZag and its data model zzstructure, asked through a specific shard-wiki question: a wiki page is linked in many independent ways at once — a namespace tree, a created-from / genealogy lineage, hyperlinks, plus shard-wiki's own shard / overlay / version / transclusion / equivalence relations. Could the information space be modelled as a zzstructure, where each relationship is a first-class dimension and none is privileged?
Distinctive material:
- the zzstructure model — cells, dimensions (edge colours), ranks, posward/negward, and the one rule that defines it: at most one posward and one negward neighbour per dimension per cell (a directed coloured multigraph)
- views — I-view (one dimension), H-view (pivot two dimensions into a cross), raster-vs-view
- trees/lists/tables as spent dimensions; many-to-many graphs as the hard case (handled by clones)
- clone ↔ transclusion convergence with the Xanadu dive

Status
Initial deep dive complete. Three new use cases promoted to spec/UseCaseCatalog.md
(UC-47 navigate-by-dimension, UC-48 H-view pivot/cross-tab, UC-49 genealogy
dimension); UC-05/17–22/26/29 enriched. A dimensional projection layer is logged
as architecture for workplans/SHARD-WP-0002-federation-architecture.md.
Recommendation recorded: adopt zzstructure as a navigation / visualization /
indexing lens (a derived dimensional projection over the union), not as the
storage substrate — Git and sovereign shards remain canonical (INTENT Stability Note).
The many-to-many hyperlink graph does not fit zzstructure's rank constraint and stays a
separate graph index. Pairs with research/260614-xanadu-deep-dive/ (clone ↔
transclusion).
