Document Components Ontology (DoCO)
========================================================================================================================

Overview
--------
DoCO, the Document Components Ontology, is an OWL 2 DL ontology that provides a general-purpose structured vocabulary
of document elements. DoCO has been designed as a general unifying ontological framework for describing different aspects
related to the content of scientific and other scholarly texts. Its primary goal has been to improve the interoperability
and shareability of academic documents (and related services) when multiple formats are actually used for their storage.

Usage Example
-------------
.. code-block:: python

    from ontolearner.ontology import DoCO

    # Initialize and load ontology
    ontology = DoCO()
    ontology.load("path/to/ontology.owl")

    # Extract datasets
    data = ontology.extract()

    # Access specific relations
    term_types = data.term_typings
    taxonomic_relations = data.type_taxonomies
    non_taxonomic_relations = data.type_non_taxonomic_relations
