Williams and Ekins summarize efforts to improve the quality of public domain chemistry databases. They found hundreds of errors in structures within the National Cancer Institute's NPC Browser shortly after its release. Through blogging and publishing papers, they aimed to alert the community about issues and the need for database curation, validation, and standardization. They propose solutions like structure filtering, provenance tracking, and collaboration between database owners to reduce errors that can inhibit scientific progress when data is reused.
