pid4cat is NFDI4Cat´s service 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. pid4cat persistent identifiers are used for samples, devices, and more, to ensure consistent tracking, integration, and accessibility of resources across both central and local RDM systems.
This repository contains the pid4cat model expressed as a LinkML model. The model is generic and may be useful beyond catalysis.
Status: beta - This is in development and may still change. We are interested in feedback of potential users. Please use issues for your comments, questions or ideas!

There are several pre-defined command-recipes available.
They are written for the command runner just. To list all pre-defined commands, run just or just --list.
