CLARIN has an arrangement with the EPIC consortium that CLARIN members will be able to register PIDs and of course resolve them. This consortium groups a number of reliable European service providers that want to participate in providing a redundant service for the research world, i.e. we are speaking about millions of PIDs and a service at very low costs. The service is based on the Handle System which according to our investigations is the only robust system meeting all requirements. No one is obliged to register Handles, but of course CLARIN centres will need to demonstrate that their PIDs can be resolved in a robust manner and offer the required functionality.
