Template to Map Cost Drivers to Data Resource Properties

Table E.1 is a template that compiles all the questions regarding the cost drivers described in Chapter 4 in a single place. Information about the definitions of all terms used is found in Chapter 4.

TABLE E.1 Cost-Driver Template

Category	Cost Driver	Decision Points/Issues
A. Content
A.1	Size (volume and number of items)	How many files will be in a single data submission? How large is an average data submission in total? Are the data sizes likely to stay stable over the life of the resource? What is the total amount of data expected? In what kind of medium will data be captured in the short and long terms?
A.2	Complexity and Diversity of Data Types	How complex is the underlying structure of the data? How are the included data to be organized? How complex is the experimental paradigm that produced the data? What sort of additional files might be necessary to upload with the data to properly understand them? How many different data types are being produced? What are the relationships among these data types (e.g., are the data correlated)?
A.3	Metadata Requirements	How much metadata must be stored with each data object to make them findable, accessible, interoperable, and reusable (FAIR)? Will metadata be entered manually by the submitter/curator? Will the data to be deposited include a data schema, or will one be generated? Is the provenance of a data set sufficiently described, or will it need to be? How much metadata can be extracted computationally?
A.4	Depth Versus Breadth	Will the repository be restricted to certain data classes or types that the repository must support?

Category	Cost Driver	Decision Points/Issues
A.5	Processing Level and Fidelity	Do the raw data need to be stored? Do processed data need to be stored? Are there compression algorithms that can reduce the file size without compromising fidelity? What kind of data structure requirements will the resource have? Is the data contributor or the repository responsible for any restructuring necessary? How is the data structure verified?
A.6	Replaceability of Data	Is the archive the primary steward of the data, or do copies exist elsewhere? Can the data be easily recreated?
B. Capabilities
B.1	User Annotation	Will the repository have to provide user annotation capabilities? What is the nature of these annotations? Are they provided by humans or machines, and how will they be authenticated? Are permissions required to annotate the data?
B.2	Persistent Identifiers	What persistent identifier (PID) scheme will be used by the archive? Is there a cost associated with using the PID? How many objects need to be identified? Who will be responsible for keeping the PIDs resolvable?
B.3	Citation	Will users be able to create arbitrary subsets of data files and mint a PID for citation? Will the repository provide machine-readable metadata for supporting data citation? Will the repository provide export of data citations for use in reference managers?
B.4	Search Capabilities	Will the repository provide a search capability for data sets? How much of the metadata will be included in search? How complex are the queries that will be supported? What types of features for search will be provided? Will the repository deploy services to search the data directly?

B.7	Data Analysis and Visualization	What types of data analyses and visualizations will the repository support? What types of other data operations will the repository support (e.g., file conversions, sequence comparison)? Do these services require significant computational resources? Who will pay for computational resources?
C. Control
C.1	Content Control	Will all appropriate data be accepted or will there be a review process? Will the review process be automated or will it require human oversight?

Category	Cost Driver	Decision Points/Issues
C.2	Quality Control	What quality control process will the repository support? Will these be automated or require human oversight? What level of data correctness will be required, and how will it be validated? What gaps in the data at the record or field level will be tolerable? Will any of the data be time sensitive, and how will data currency be ensured? How will duplication within or between data sets be addressed? Will prevalidation guidelines or routines be distributed by the resource to the data contributors? Will human curation be necessary?
C.3	Access Control	What types of access control are required for the repository (e.g., will there be an embargo period)? At what level are they instituted (e.g., individual users, individual data sets)? Does use of the data require approval by a data access committee?
C.4	Platform Control	Are there restrictions on the type of platform that may or must be used?
D. External Context
D.1	Resource Replication	Is there a requirement to replicate the information resource at multiple sites (i.e., mirroring)?
D.2	External Information Dependencies	Will the resource be dependent on information maintained by an outside source?
D.3	Distinctiveness	Are there existing resources available that provide similar types of data and services?
E. Data Life Cycle
E.1	Anticipated Growth	Is the repository expected to continuously grow over its lifetime? Is the likely rate of growth in data and services known? Is the use of the repository likely to grow over time? Is the likely growth of the user base known?
E.2	Update and Versions	Will the deposited data require updates (e.g., in response to new data or error corrections)? Will prior versions of the data need to be retained and made available locally or in a different resource? How frequently will individual data sets be updated?
E.3	Useful Lifetime	Are the data to be housed likely to have a limited period of usefulness? Does the resource have a defined period of time for which it will operate? Does the resource have to provide a guarantee that the data will be available for a finite period of time (e.g., 10 years)?
E.4	Offline and Deep Storage	Can the resource take advantage of offline storage for data that are not heavily used? Does the resource have a plan for moving unused data to deep storage (i.e., State 3)?

F. Contributors and Users
F.1	Contributor Base	Is the number of contributors known? If not, can it be estimated? Are all the data originating from the same source (e.g., a single instrument or a single organization)? How will data be transferred into the data resource (e.g., periodic large batches, more frequent smaller data sets, constantly streamed, by physical transfer)? Will the data be pushed by the contributor or pulled by the resource? Are there direct or indirect fees associated with acquiring the data from a source? Will a data steward be available from among the contributors to assist with any data integration into the data resource?
F.2	User Base and Usage Scenarios	How many users will likely access the data? What will be the frequency of access? How will users access the data? Will the resource be building analysis tools? Will the resource support individual file download or bulk download? Will there be any fees for downloading/accessing the data? How many different types of users must be supported?
F.3	Training and Support Requirements	Will training for resource use be offered? What form will the training take? Will a “help desk” be provided? When does live help need to be available? What is the expected skill level of the user base?
F.4	Outreach	Does the existence of the repository need to be advertised? How many conferences per year should resource representatives attend? Will the resource have a booth at the conference for live demos or conduct hands-on tutorials? Are users required by funders or journals to deposit data in the repository?
G. Availability
G.1	Tolerance for Outages	What is the tolerance for outages of the resource? What measures will be taken to avoid and mitigate outages? How quickly and completely does the resource need to recover from an outage?
G.2	Currency	How often will the data be released? How soon do data need to be made available after they are received?
