kgcl

is a Data Model.

A data model for describing change operations at a high level on an ontology or ontology-like artefact, such as a Knowledge Graph. KGCL enables standardized representation of changes in ontologies and knowledge graphs for tracking, auditing, and reproducibility. It provides a formal language for representing and documenting changes in knowledge graphs, facilitating version control, change history, and collaboration.

Overview

KGCL (Knowledge Graph Change Language) is a standard datamodel for representing changes in ontologies and knowledge graphs. It provides a formal way to describe operations such as node creation, edge modification, and entity obsolescence while preserving the history and intent behind each change.

Purpose

The primary purposes of KGCL are:

  1. Tracking Changes: Enables detailed tracking of every modification made to knowledge resources
  2. Reproducibility: Ensures reproducible workflows for ontology and knowledge graph maintenance
  3. Auditability: Provides mechanisms for auditing changes over time
  4. Collaboration: Facilitates coordination among multiple editors working on shared knowledge resources
  5. Tools Integration: Creates a standardized language that various tools can implement for consistent change management

Components

KGCL consists of:

  • A formal schema defining change operations
  • Various serializations including OWL, OBO, SHACL, and YAML
  • A Python implementation with a LinkML model and LARK grammar parser
  • JSON-LD contexts for semantic web integration

Usage

KGCL can be used for:

  • Maintaining ontologies with complex editing workflows
  • Documenting changes in versioned knowledge graphs
  • Enabling programmatic applications to generate and interpret change operations
  • Creating human-readable reports of modifications to knowledge resources
  • Supporting quality control processes in collaborative ontology development
