|
Overview |
|
|
-------- |
|
|
The AFO is an ontology suite that provides a standard vocabulary and semantic model |
|
|
for the representation of laboratory analytical processes. The AFO suite is aligned at the upper layer |
|
|
to the Basic Formal Ontology (BFO). The core domains modeled include, Equipment, Material, Process, and Results. |
|
|
This artifact contains all triples of Allotrope Foundation Merged Without QUDT Ontology Suite (REC/2023/12) |
|
|
together with triples inferred with HermiT. |

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