linkml-toolkit 0.1.0

A simple toolkit for working with LinkML schemas

LinkML Toolkit (lmtk)

A simple toolkit for working with LinkML schemas. This tool offers advanced schema analysis, validation, transformation, and visualization capabilities through a flexible command-line interface.

🌟 Features

• Schema Analysis

  • Generate schema summaries.
  • Detailed views of classes, slots, and types.
  • Support for hierarchical and section-based analysis.

• Schema Validation

  • Rigorous validation checks with detailed error reporting.
  • Optional metadata display for schemas.

• Schema Operations

  • Merge or concatenate multiple schemas.
  • Subset schemas by specified classes.

• Format Conversion

  • Export schemas to JSON, RDF, GraphQL, CSV, TSV, and SQL formats.
  • Customize RDF serialization formats (e.g., Turtle, XML).
  • SQL export supporting PostgreSQL, MySQL, SQLite, and DuckDB dialects.

• Visualization

  • Generate interactive HTML visualizations of schemas.
  • Options for inheritance, descriptions, and statistics display.

📚 Usage

Core Commands

Schema Summary

# Generate a summary of the schema
lmtk summary --schema schema.yaml

# Detailed view for specific sections
lmtk summary --schema schema.yaml --section slots --detailed

# Export summary to JSON
lmtk summary --schema schema.yaml --output summary.json

Schema Validation

# Validate schema
lmtk validate --schema schema.yaml

# Validate with metadata display
lmtk validate --schema schema.yaml --metadata

Schema Export

# Export to JSON Schema
lmtk export --schema schema.yaml --format json --output schema.json

# Export to RDF (Turtle format)
lmtk export --schema schema.yaml --format rdf --rdf-format turtle --output schema.ttl

# Export to SQL (PostgreSQL dialect)
lmtk export --schema schema.yaml --format sql --sql-dialect postgresql --output schema.sql

Schema Subset

# Create a subset containing specific classes
lmtk subset --schema schema.yaml --classes class1,class2 --output subset.yaml

# Exclude inherited elements
lmtk subset --schema schema.yaml --classes class1 --no-inherited --output subset.yaml

Schema Combination

# Merge schemas
lmtk combine --schema base.yaml --additional-schemas schema1.yaml -a schema2.yaml --mode merge --output merged.yaml

# Concatenate schemas
lmtk combine --schema base.yaml --additional-schemas schema1.yaml -a schema2.yaml --mode concat --output concatenated.yaml

Schema Visualization

# Generate an interactive HTML visualization
lmtk visualize --schema schema.yaml --output visualization.html

# Generate full documentation bundle
lmtk visualize --schema schema.yaml --output docs/ --full-docs
