pyArchimate package
Documentation: readthedocs.org
pyArchimate is a Python library for programmatically reading, writing, and manipulating Open Group ArchiMate enterprise architecture models. It has no GUI — it is purely a file I/O and object model library designed for batch and scripting use.
Core concepts
| Object | What it represents |
|---|---|
Model |
Top-level container for everything |
Element |
An architectural concept (business process, application, server, capability…) |
Relationship |
A typed link between two elements (Association, Realization, Composition, Flow…) |
View |
A diagram — a named subset of elements/relationships laid out visually |
Node |
The visual box representing an element inside a view |
Connection |
The visual arrow representing a relationship inside a view |
Elements span the full ArchiMate 3 layer stack: Strategy, Motivation, Business, Application, Technology, Physical, and Implementation.
Supported formats
| Format | Read | Write |
|---|---|---|
| ArchiMate Open Exchange XML | yes | yes |
| Archi tool format (.archimate) | yes | yes |
| CSV | — | yes |
Key operations
- Read / Write / Merge — load one or more files and save to any supported format
- Create & modify — add elements, relationships, and views via the API without touching a file
- Filter — extract subsets of elements, relationships, or views by custom predicates
- Style — set colours, coordinates, dimensions, and text layout on nodes
- Validate — check for broken references and invalid connections
- Auto-Layout — automatically arrange view elements using force-directed or hierarchical algorithms
- Auto-Format — standardize element sizes, fonts, and alignment per ArchiMate conventions
- SVG Export — render views as self-contained SVG with ArchiMate symbols and standard colors
Auto-Layout and Auto-Format (BETA)
⚠️ Status: BETA — Core functionality is stable and production-ready for typical use cases. API may evolve based on user feedback.
Quick Start
from pyArchimate.view import load_view, save_view
from pyArchimate.view.layout import apply_layout, apply_format, LayoutConfig
# Load a view
view = load_view("architecture.archimate")
# Apply automatic layout
result = apply_layout(view)
# Or apply formatting only (without repositioning)
result = apply_format(view)
# Export as SVG
svg = view.to_svg(filepath="diagram.svg")
# Save the laid-out view
save_view(view, "laid_out.archimate")
Features
- Two layout algorithms: Force-directed (general-purpose) and hierarchical (organizational structures)
- Respect ArchiMate layers: Business → Application → Technology ordering enforced
- Connection routing: Orthogonal polylines with intelligent label placement
- SVG export: Self-contained SVG with all 30+ ArchiMate element types and standard colors
- Undo/rollback: Revert layout changes with
undo_layout(view) - Configuration: Customize spacing, margins, alignment, element exclusion, and routing style
Performance
| View Size | Force-Directed | Hierarchical |
|---|---|---|
| 100 elements | <200ms | <50ms |
| 300 elements | <2s | <500ms |
| 500 elements | <5s | <1s |

ArchiMate v3.x Compliance
pyArchimate now supports ArchiMate 3.x specification compliance with the following features:
Supported Features
- ✅ BusinessInteraction elements: Full support for creating, importing, and exporting BusinessInteraction elements
- ✅ Influence strength metadata: Complete round-trip preservation of influence relationship strength (both
.archimateand OpenGroup formats) - ✅ Relationship documentation: Full preservation of relationship documentation/description text during import and export
Known Gaps
See Gap Analysis Documentation for detailed analysis of specification alignment and areas for future enhancement (P2/P3).
