The TTRAM (Transparent Trustworthy Repository Attributes Matrix) is a flexible, evolving tool to support mutual understanding, support and alignment within and beyond the FIDELIS Network. This document provides a brief guide to the simple TTRAM Template. Comments and suggestions are welcome this shared document or via fidelis.matrixfeedback-request@postit.csc.fi. An Introduction and Overview paper provides more detail on how it can be deployed, populated and expanded. The parameters and drivers behind the selection of the activities and functions (A|F), levels of retention, curation and preservation (LoRCAP) and the digital object, depositor and user characteristics supported by different repository types are covered in a separate Design Statement.
