| Materials Data Science Ontology (MDS) |
| ======================================================================================================================== |
|
|
| Overview |
| -------- |
| Materials Data Science (MDS) is an ontology encompassing multiple domains relevant to materials science, |
| chemical synthesis and characterizations, photovoltaics and geospatial datasets. The terms used for classes, |
| subclasses and instances are mapped to PMDCo and BFO Ontologies. |

| Usage Example |
| ------------- |
| .. code-block:: python |
|
|
| from ontolearner.ontology import MDS |
|
|
| # Initialize and load ontology |
| ontology = MDS() |
| ontology.load("path/to/ontology.TTL") |
|
|
| # 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 |
