Module P2OWL2generator
Package OWL2generator

Class OWL2_Generator

java.lang.Object
OWL2generator.OWL2_Generator
public class OWL2_Generator
extends java.lang.Object
The OWL2_Generator class serves as the core application logic within a Java framework for generating OWL/XML ontologies: It leverages text files containing configuration details to construct the ontology structure. This class acts as the central controller, directing the overall process of ontology generation based on user-provided configuration files.

Key Functionalities:

Processes Command Line Arguments: Evaluates user-provided arguments to determine the input/output directory for text files used during generation.

Controls Ontology Generation Sequence: Orchestrates the creation of the ontology by calling dedicated modules responsible for:

  • Generating the OWL header
  • Defining class structures
  • Setting class disjointness
  • Defining object property triplets (relationships between individuals)

Manages Configuration Files: Employs separate text files for each generation step, allowing for modularity and customization.

Logs Console Messages: Provides informative messages during execution to track progress.

Additional Notes:

The class utilizes pre-defined file paths and comments within the code, suggesting potential improvements for user-configurable settings.

The comments indicate the framework's reliance on external classes.
