Planar Defects Ontology (PLDO)¶
The Planar Defects Ontology (PLDO) is an ontology designed to describe planar defects in crystalline materials, including defect types such as grain boundaries and stacking faults [1] [2]. It provides a structured vocabulary for representing planar-defect concepts and their associated properties and relationships in materials science [1] [2].
PLDO supports the semantic representation and annotation of information related to planar defects, helping to organize defect-related knowledge and facilitate interoperability, data integration, querying, and reuse across materials science applications [1] [2]. By providing a common terminology for planar defects, PLDO enables consistent description and comparison of defect-related information in crystalline materials [2].
Example Usage: Annotate experimental or computational materials data with PLDO terms to describe planar defects such as grain boundaries and stacking faults, together with their associated properties and relationships, enabling consistent representation and integration of planar-defect information [1] [2].

Usage Example¶
Use the following code to import this ontology programmatically:
from ontolearner.ontology import PLDO
ontology = PLDO()
ontology.load("path/to/PLDO-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
