Overview |
|
|
-------- |
|
|
The PMD Core Ontology (PMDco) is a comprehensive framework for representing knowledge that encompasses |
|
|
fundamental concepts from the domains of materials science and engineering (MSE). The PMDco |
|
|
has been designed as a mid-level ontology to establish a connection between specific MSE application ontologies |
|
|
and the domain neutral concepts found in established top-level ontologies. The primary goal of the PMDco |
|
|
is to promote interoperability between diverse domains. |

------------- |
|
|
.. code-block:: python |
|
|
|
|
|
from ontolearner.ontology import PMDco |
|
|
|
|
|
# Initialize and load ontology |
|
|
ontology = PMDco() |
|
|
ontology.load("path/to/ontology.OWL") |
|
|
|
|
|
# Extract datasets |
|
|
data = ontology.extract() |
|
|
|
|
|
# Access specific relations |
|
|
term_types = data.term_typings |
|
|
taxonomic_relations = data.type_taxonomies |
