OntoGraph

OntoGraph is a C++ tool that converts RDF/XML ontologies into graph structures, enabling traversal and search using standard graph algorithms. It is designed for researchers and developers working with ontologies who need to analyze, traverse, or manipulate ontology data as graphs.

Features

  • RDF/XML Parsing: Converts RDF/XML files into an in-memory graph.
  • Graph Representation: Nodes, edges, and attributes are extracted from ontology data.
  • Graph Algorithms: Supports depth-first search (DFS), predicate-based traversal, and exclusion of predicates.
  • Attribute Access: Retrieve node attributes and relationships for advanced analysis.

Installation

Prerequisites

  • C++20 compatible compiler
  • CMake >= 3.22
  • Conan (for dependency management)
  • tinyxml2 (handled via Conan)

Build Steps

  1. Clone the repository:

    git clone <repo-url>
cd OntoGraph

  2. Install dependencies with Conan:

    conan install . --output-folder=build --build=missing

  3. Build the project with CMake:

    cmake -S . -B build
cmake --preset conan-debug
cmake --build --preset conan-debug

This will produce the ontograph_cli executable in the build/app directory.

Usage

Command-Line Example

Need to be implemented ... Currently: Edit app/main.cpp to point to your RDF/XML file and adjust traversal as needed.

Running the CLI

After building, run:

./build/app/ontograph_cli
