pkg_resources import fails with Setuptools 72.0.0+

[arthurbdiniz]

Description

The package currently uses pkg_resources.resource_filename to load the ActivityStreams 2.0 context file. However, pkg_resources has been removed from Setuptools 72.0.0+, causing import errors in environments with newer Setuptools versions.

---

Error

from pkg_resources import resource_filename
ModuleNotFoundError: No module named 'pkg_resources'

---

Environment

• Setuptools version: 72.0.0+
• Python version: [any]

---

Impact

This prevents the package from being imported in environments with recent Setuptools versions, making it unusable without downgrading Setuptools.

---

Root Cause

The pkg_resources module was deprecated and has been removed from Setuptools. See:

• Setuptools should not rely on pkg_resources pypa/setuptools#3085
• https://setuptools.pypa.io/en/latest/pkg_resources.html (deprecated notice)
