Developers work with native Python objects, while the library ensures that valid RDF is generated and inserted. - ---- - -## Fine-Grained / Manual Mode - -For cases where strict parity with the Java API is required, the library also allows manual construction: - -```python -p1 = Property(...) -t1 = Type(properties=[p1, ...]) -``` - -This low-level interface mirrors the Java implementation, but is rarely needed in typical Python workflows. - ---- - -## Conformity and Interoperability - -Internally, the library converts objects into `RdfsClasses` and `RdfTypes`. -A Java-style API is exposed where necessary to meet openBIS interoperability requirements. - -However, the **preferred approach in Python** is to work with Pydantic models and high-level functions (`read_as`, `add`, `add_to_schema`). This avoids boilerplate, reduces errors, and provides strong validation guarantees out of the box. - ---- - -## Why the Pythonic Approach Is Better - -* **Java style**: verbose builders, string references, manual wiring. -* **Python style**: typed models, declarative APIs, validation by design. - -Both approaches remain interoperable, but the Pythonic path is safer, faster, and more natural
