Extended Matrix is a method (the formal language), a framework (a family of open-source tools), and a community. Three short paths below — each leads you straight to where the work happens.

Sources, stratigraphy, reconstruction

For archaeologists, heritage scholars, students.

Begin with the formal language: it is what you will read, write and discuss when reasoning about evidence. Pencil and paper are enough to start.

Read the Learn EM guide.
Walk through stratigraphic nodes and paradata nodes.
Hands-on: install yEd with the EM palette and draw your first graph.

3D models annotated with EM data

For 3D artists, modellers, technical-archaeologists.

Bring an existing graph into Blender, link proxies to stratigraphic units, drive visualisation by epoch and property, export to the web.

Install EM Tools (Blender extension).
Follow creating your first matrix, then the intermediate tutorial track.
Publish to the web with Heriverse.

Extend, integrate, contribute

For developers and tool-builders.

EM is implemented as a Python knowledge-graph library (s3dgraphy) you can plug into any platform — Revit, 3ds Max, Unity, Unreal, custom pipelines.

pip install s3dgraphy and read the repository README.
For the Blender add-on, see development setup and API reference.
Open an issue or join the Telegram group.
