momapy_kb

A library to integrate momapy maps into graph databases and logic programming backends.

Built on top of fieldz_kb, momapy_kb provides:

• Multiple LPG backends -- Neo4j, FalkorDB, FalkorDBLite (embedded)
• Clingo/ASP backend -- convert maps to logic programming facts
• File-based loading -- save maps directly from CellDesigner, SBGN, and SBML files
• Collection management -- organize maps into named collections
• Custom type plugins -- handles momapy-specific types (LayoutModelMapping, NoneValue, FrozenSurjectionDict)
• Layout element queries -- query model elements and retrieve corresponding layout elements for rendering

Installation

pip install momapy-kb[neo4j]        # Neo4j support
pip install momapy-kb[falkordb]     # FalkorDB support
pip install momapy-kb[falkordblite] # FalkorDBLite (embedded) support
pip install momapy-kb[clingo]       # Clingo/ASP support
pip install momapy-kb[all]          # Everything

Quick example

import momapy_kb.lpg.session
import momapy_kb.lpg.backends.neo4j

backend = momapy_kb.lpg.backends.neo4j.Neo4jBackend(
    hostname="localhost",
    username="neo4j",
    password="password",
)

with momapy_kb.lpg.session.Session(backend) as session:
    # Save a map from a CellDesigner file
    session.save_from_file("model.xml", integration_mode="hash")

    # Query model elements
    results = session.execute_query_as_objects(
        "MATCH (n:Macromolecule) RETURN n"
    )

    # Get layout elements for rendering
    layout_results = session.cypher_query_as_layout_elements(
        "MATCH (n:GenericProcess) RETURN n"
    )
