Data Access and Acknowledgement

1. All investigators participating in CHEESEHEAD agree to promptly submit their final Quality Controlled data to the CHEESEHEAD Data Archive Center (CDAC) or associated data archive center(s) at the latest by 11 April 2020 (six months after the end of the CHEESEHEAD Field Project Deployment) to facilitate inter-comparison of results, quality control checks and inter-calibrations, as well as an integrated interpretation of the combined dataset.
   
    
2. All data shall be promptly provided to other CHEESEHEAD investigators upon request. All CHEESEHEAD investigators will have equal access to all data.
   
    
3. Investigator(s) who collected the data must be notified first of the intent to use the data, in particular if data is to be provided to a third party (e.g., journal articles, presentations, research proposals, other investigators). Investigator permissions and requirements must be met prior to sharing data publicly. It is strongly encouraged that PIs responsible for acquisition of data be invited to become collaborators and co-authors on any projects, publications and presentations. If the contribution of the data product is significant to the publication, the PIs responsible for generating a measurement or a data product should be offered the right of co-authorship. Any use of the data should include an acknowledgment (i.e., citation). In all circumstances, the PIs responsible for acquisition of data should be acknowledged appropriately. Users of the data are strongly encouraged to contact the relevant PIs prior to incorporating it into peer-reviewed publications.
   
    
4. International agencies, professional societies, and research organizations are moving towards requiring researchers to formally cite data and sources that led to a given research result. To support this, DOIs or Digital Object Identifiers (considered “perpetual” identifiers) will be assigned to final datasets housed within the CDAC. These DOIs should be used in CHEESEHEAD related publications. DOIs will not be created for preliminary data in the CDAC.
   
    
5.  Additional details regarding the data provider responsibilities, author acknowledgements, preliminary data storage and data to be produced can be found in the CHEESEHEAD Data Management Plan.
