This document provides a template and guidance to the formulation of Long-Term Preservation (LTP) policies for research data repositories. A section about cost modelling for LTP is also included. The aim of this document is to assist research data repositories to formulate a Long-Term Preservation (LTP) policy for the provision of their data services. The policy template intends to be generic, so that it can be used by a wide range of repositories and policy-based data archives to compose their LTP policies. This publication consists of three files: Long-Term Preservation Policies for Research Data Repositories a Template.pdf (complete report including the LTP policy template) Template for LTP Policies.pdf (Standalone LTP policy template in pdf format) Template for LTP Policies.docx (Standalone LTP policy template in ms-word format) The report consists of four parts: Part I: Provides considerations and explanations of the approach followed. Part II: The LTP Policy Template. Part III: Appendices, providing further detail or explanation. Part VI: Specific appendices for EUDAT services B2SHARE and B2SAFE.
