s3dgraphy 0.1.39

3D Stratigraphic Graph Management Library for archaeological and heritage applications

s3dgraphy

3D Stratigraphic Graph Management Library

s3dgraphy is a Python library for creating and managing multitemporal, 3D knowledge graphs, with a focus on archaeological and heritage applications. It provides tools for stratigraphic data management, temporal modeling, and graph-based analysis of archaeological contexts.

Part of the Extended Matrix Framework, s3dgraphy implements the formal language Extended Matrix (EM) for archaeological documentation and 3D reconstruction workflows.

🚀 Installation

# From PyPI (stable releases)
pip install s3dgraphy

# From TestPyPI (development versions)
pip install --index-url https://test.pypi.org/simple/ s3dgraphy

# With optional dependencies
pip install s3dgraphy[visualization]  # For plotting features
pip install s3dgraphy[full]          # All optional dependencies

🔧 Quick Start

import s3dgraphy

# Create a new stratigraphic graph
graph = s3dgraphy.Graph()

# Add stratigraphic units
us1 = graph.add_node("US001", node_type="US", 
                     properties={"period": "Roman", "material": "pottery"})
us2 = graph.add_node("US002", node_type="US", 
                     properties={"period": "Medieval", "material": "stone"})

# Add stratigraphic relationships
graph.add_edge(us1, us2, edge_type="ABOVE", 
               properties={"certainty": "high"})

# Query the graph
print(f"Graph contains {len(graph.nodes)} stratigraphic units")
print(f"Relationships: {len(graph.edges)}")

# Export to different formats
graph.export_graphml("stratigraphy.graphml")
graph.export_json("stratigraphy.json")
