  Data only generates value for a few organizations with expertise and
resources to make data shareable, discoverable, and easy to integrate. Sharing
data that is easy to discover and integrate is hard because data owners lack
information (who needs what data) and they do not have incentives to prepare
the data in a way that is easy to consume by others.
  In this paper, we propose data market platforms to address the lack of
information and incentives and tackle the problems of data sharing, discovery,
and integration. In a data market platform, data owners want to share data
because they will be rewarded if they do so. Consumers are encouraged to share
their data needs because the market will solve the discovery and integration
problem for them in exchange for some form of currency.
  We consider internal markets that operate within organizations to bring down
data silos, as well as external markets that operate across organizations to
increase the value of data for everybody. We outline a research agenda that
revolves around two problems. The problem of market design, or how to design
rules that lead to the outcomes we want, and the systems problem, how to
implement the market and enforce the rules. Treating data as a first-class
asset is sorely needed to extend the value of data to more organizations, and
we propose data market platforms as one mechanism to achieve this goal.
