+# dcat_ap_plus
+
+Extension of the DCAT Application Profile (DCAT-AP) that adds links to use-case specific context. It enables describing:
+
+- which entities or activities were evaluated (the dataset is about),
+- which activity generated the dataset, including instruments, environment (e.g., lab), and plan,
+- which qualitative and quantitative characteristics were attributed to evaluated entities/activities and used instruments.
+
+This package ships the LinkML-generated Python datamodel for the schema.
+Two versions of the datamodel are provided: one using Python dataclasses and another using Pydantic.
+
+## Installation
+
+```powershell
+pip install dcat_ap_plus
+```
+
+Requires Python >= 3.9, < 4.0.
+
+## Quick start
+
+```python
+import dcat_ap_plus
+print(dcat_ap_plus.__version__)
+
+# Work with the generated datamodel (Python dataclasses)
+from dcat_ap_plus.datamodel.dcat_ap_plus import Dataset, DataGeneratingActivity
+
+ds = Dataset(
+    id="ex:dataset1",
+    title="Example dataset",
+    description="A minimal dataset for quickstart.",
+    was_generated_by=[DataGeneratingActivity(id="ex:act1")],
+)
+print(ds)
+```
