of the Renaissance’s "Scientific Revolution." Galileo’s notes, and the  key publication based on them \cite{galilei}, directly integrated his **data** (drawings of Jupiter and its  moons), key **metadata** (timing of each observation, weather, telescope  properties), and **text** (descriptions of methods, analysis, and conclusions). (See Figure \label{fig:1}) conclusions), as shown in \label{fig:1}.  Today, many research projects are considered complete when the analysis is complete, and a short journal article has been written and published. But modern scientific publications almost never offer enough access to data and metadata to be used as the sole guide to repeating, or statistically verifying, scientific studies. Worse, researchers seeking to extend work based on others' (or even their own!) data, frequently have trouble finding those data.
