The implementation of Persistent Identifiers (pid) for Spatial objects is one of the most immediate challenges in the implementation of the INSPIRE Directive. This project aims to build a framework for implementing Persistent Identifiers able to be dereferenced for INSPIRE resources in Spain.

A script to monitor status of B2ΗANDLE.B2HANDLE is EUDAT's main Persistent Identifier (PID) service. B2HANDLE is a distributed service, designed to contribute to data persistency by maintaining opaque, globally unique PIDs.
