| Bibliographic Framework Ontology (BIBFRAME) |
| ======================================================================================================================== |
|
|
| Overview |
| -------- |
| The Bibframe vocabulary consists of RDF classes and properties used for the description of |
| items cataloged principally by libraries, but may also be used to describe items cataloged by museums and archives. |
| Classes include the three core classes - Work, Instance, and Item - in addition to many more |
| classes to support description. Properties describe characteristics of the resource being |
| described as well as relationships among resources. For example: one Work |
| might be a "translation of" another Work; an Instance may be an |
| "instance of" a particular Bibframe Work. Other properties describe attributes of Works and Instances. For |
| example: the Bibframe property "subject" expresses an important attribute of a Work |
| (what the Work is about), and the property "extent" (e.g. number of pages) expresses an |
| attribute of an Instance. |

| .. code-block:: python |
|
|
| from ontolearner.ontology import BIBFRAME |
|
|
| # Initialize and load ontology |
| ontology = BIBFRAME() |
| ontology.load("path/to/ontology.RDF") |
|
