  Goal 1 of the National Academies of Science, Engineering and Mathematics
Exoplanet Science Strategy is "to understand the formation and evolution of
planetary systems as products of the process of star formation, and
characterize and explain the diversity of planetary system architectures,
planetary compositions, and planetary environments produced by these
processes", with the finding that "Current knowledge of the demographics and
characteristics of planets and their systems is substantially incomplete." One
significant roadblock to our ongoing efforts to improve our demographics
analyses is the lack of comprehensive meta-data accompanying published
exoplanet surveys. The Exoplanet Program Analysis Group (ExoPAG) Science
Interest Group 2: Exoplanet Demographics has prepared this document to provide
guidance to survey architects, authors, referees and funding agencies as to the
most valuable such data products for five different exoplanet detection
techniques - transit, radial velocity, direct imaging, microlensing and
astrometry. We find that making these additional data easily available would
greatly enhance the community's ability to perform robust, reproducible
demographics analyses, and make progress on achieving the most important goals
identified by the exoplanet and wider astronomical community.
