This document discusses the need to move away from solely relying on "trusted sources" for scientific data and instead adopt a model based on transparency and provenance. It provides examples of projects that aim to make chemical data like melting points more open and transparent by curating data from various sources and recording experiments and findings in open notebooks. This allows inconsistencies and outliers in data to be identified and resolved over time through collaboration. The goal is to enable faster and better science through open sharing of data and methods.
