Extended Matrix Development Projects

Three-level architecture

Extended Matrix (Language) — Nodes and node variants formalizing virtual reconstruction. Expandable through new node types. Currently expressed in yEd/GraphML; s3Dgraphy provides a richer property graph underneath. s3Dgraphy JSON config files encode the formal rules and are part of the core language.

Extended Matrix Framework — Tools ecosystem: EMtools (Blender add-on), s3Dgraphy (Python library), 3D Survey Collection (3DSC, photogrammetry & 3D model preparation), Heriverse (online viewer), Tapestry (AI-based proxy rendering), external standalone tools, connectors. Separation of responsibilities enables parallel development.

Governance Cycle — EM advances every 6 months. A Component is a new node or a tool using/expanding existing nodes. A Development Project impacts one or more Components. Each DP requires a Key Study with open data.

DP Lifecycle

Proposal (with Key Study) → Development → Community Review → Candidate for EM Version → Inclusion

StratiGraph EU Project

Several Development Projects are funded or developed within StratiGraph, a European project supporting the creation of a collaborative infrastructure for stratigraphic heritage documentation. DPs tagged with StratiGraph were created or advanced as part of this initiative. Use the StratiGraph filter to isolate them.
