Molecular Process Ontology (MOP)

The Molecular Process Ontology (MOP) is a systematic ontology for describing and classifying molecular-level chemical processes and transformations [1] [2]. It provides a structured vocabulary for representing processes such as cyclization, methylation, demethylation, oxidation, reduction, and other fundamental transformations relevant to chemical reaction description [1] [2].

MOP supports standardized semantic representation of molecular processes that underlie reaction mechanisms and can be used to organize and classify reaction information in chemistry databases and reaction informatics systems [1] [2]. By providing explicit terms for molecular transformations, MOP supports semantic interoperability, structured querying, and mechanism-oriented analysis across chemical data resources [1] [2].

Example Usage: Represent a cyclization reaction step by linking it to an appropriate MOP term for the corresponding molecular process, such as a ring-closure transformation, enabling structured classification of reactions and discovery of related transformations across chemical databases [1] [2].

Usage Example

Use the following code to import this ontology programmatically:

from ontolearner.ontology import MOP

ontology = MOP()
ontology.load("path/to/MOP-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
