Tools to manage and estimate costs have not been integrated into other digital curation processes or tools. To determine why that is so a consortium of 13 European cost modeling specialists launched the Collaboration to Clarify the Costs of Curation (4C) project.
4C seeks to help organizations better understand the costs and benefits of digital curation and preservation, and to help users draw together existing and useful resources so they can both make their own assessment of existing models and develop their own cost modeling exercises. The Curation Costs Exchange (CCEx), a platform for the exchange and comparison of digital curation costs and cost information, is a key 4C project deliverable developed to support these goals.
The Cost Comparison Tool enables the exchange of sensitive data and gives users the opportunity to identify greater efficiencies, better practices, and valuable information exchanges among peers. There is also the Understand Your Costs toolkit. The Economic Sustainability Reference model highlights key digital curation concepts, relationships, and decision points in a complex problem space, helping users benchmark and compare their own local models.
