Collaboration to Clarify the Costs of Curation
What isn’t it?
It is not a
unified, functional, implementable
cost modelling
method, model or tool.
![Page 3: Cost Concept Model & Gateway Requirements Specification Group_CCM... · Cost Concept Model & Gateway Requirements Specification Hervé L’Hours-UK Data Archive Archiving 2014 Berlin](https://reader034.vdocuments.net/reader034/viewer/2022042805/5f5e19e993f33b1ffa795e01/html5/thumbnails/3.jpg)
Collaboration to Clarify the Costs of Curation
What is it
• A framework consisting of a cost concept model and gateway specification to support future research and development
– Explaining the problems and challenges
– Proposing a coherent approach to modelling, documentation and tool development issues
![Page 4: Cost Concept Model & Gateway Requirements Specification Group_CCM... · Cost Concept Model & Gateway Requirements Specification Hervé L’Hours-UK Data Archive Archiving 2014 Berlin](https://reader034.vdocuments.net/reader034/viewer/2022042805/5f5e19e993f33b1ffa795e01/html5/thumbnails/4.jpg)
Collaboration to Clarify the Costs of Curation
What & What?
A framework consisting of:
Cost Concept Model“Core” concepts at the heart of most curation cost methodologies.
Gateway SpecificationA structured approach to support future research and development.
![Page 5: Cost Concept Model & Gateway Requirements Specification Group_CCM... · Cost Concept Model & Gateway Requirements Specification Hervé L’Hours-UK Data Archive Archiving 2014 Berlin](https://reader034.vdocuments.net/reader034/viewer/2022042805/5f5e19e993f33b1ffa795e01/html5/thumbnails/5.jpg)
Collaboration to Clarify the Costs of Curation
Why?
Because existing cost models are difficult to:
• understand
• compare
• select
![Page 6: Cost Concept Model & Gateway Requirements Specification Group_CCM... · Cost Concept Model & Gateway Requirements Specification Hervé L’Hours-UK Data Archive Archiving 2014 Berlin](https://reader034.vdocuments.net/reader034/viewer/2022042805/5f5e19e993f33b1ffa795e01/html5/thumbnails/6.jpg)
Collaboration to Clarify the Costs of Curation
What are the goals?
Make future cost model work
• easier to evaluate and compare in terms of: – Scope
– Effort
– Accuracy
• Improve supporting documentation
• Drive appropriate adoption

Collaboration to Clarify the Costs of Curation
The Core Concept Model
• “Core” concepts at the heart of most curation cost methodologies
• Clearly defined
– Suitable for re-use in future curation cost models
• Need to be extended to support a method

Methods, Models and Tools
A ‘Cost Model’ usually consists of: • Some use cases or scenarios• A model of the variables from the underlying
curation system necessary to support the method• The method which applies the
calculations/comparisons to the model to deliver the conclusions required by the use cases
• A tool for data entry and calculations
