Python package for pid4cat persistent identifiers

The package helps to interface the pid4cat service, a service offered by NFDI4Cat for metadata rich, universal persistent identifiers. pid4cat builds upon the handle-system (as DOIs do). pid4cat adds a custom API to a handle server and provides a LinkML model for PID-related metadata. The metadata are stored in the handle records.

This Python package includes an equivalent Python (pydantic) model of the LinkML-based datamodel for the metadata of pid4cat identifiers. It moreover includes some helpers to simplify using pid4cat identifiers.

Installation
