The Reproducible Research movement and the like have been trying to gain ground in many different areas since at least 2009 [1].
Too bad its adoption hasn't grown faster. Especially with all the recent focus on "big data", applied machine learning, and computational science papers. It's hard to actually measure the quality and contributions of most of them.
Not having an accepted method to cite and share datasets is also part of the problem.
