Summary

ApartoftheNSFBigDataregionalinnovationhubprogram,theNortheasthub,isaddressingkeydatasharingchallengesby:

• Creatingalicensingmodelfordatathatfacilitatessharingdatathatisnotnecessarilyopenorfreebetweendifferentorganizations,

• Developingaprototypedatasharingsoftwareplatform,ShareDB,whichwillenforcesthetermsandrestrictionsofthedevelopedlicenses,and

• Developingandintegratingrelevantmetadatathatwillaccompanythedatasetssharedunderthedifferentlicenses,makingthemeasilysearchableandinterpretable.

Toensurethatthedevelopedtoolsandlicensesareuseful,theprojectwillformtheNortheastDataSharingGroup,comprisedofmanydifferentstakeholderstomakethelicensingmodelwidelyacceptedandusableinmanyapplicationdomains(e.g.,healthandfinance).

Rationale

Sharingofdatasetscanprovidetremendousmutualbenefitsforindustry,researchers,andnonprofitorganizations.Amajorobstacleisthatdataoftencomeswithprohibitiverestrictionsonhowitcanbeused(e.g.,requiringtheenforcementoflegaltermsorotherpolicies,handlingdataprivacyissues,etc.).Additionally,manyattemptstosharerelevantdatasetsbetweendifferentstakeholdersinindustryandacademiafailorrequirealargeinvestmenttomakedatasharingpossible.
