1. What are the existing standardized column names within the different slots of PharmacoSet?
2. What, if any, additional columns do we want to add as mandatory?
3. What, if any, additional optional metadata columns do we want to standardize?

4. Should the metadata be confined to lab curated annotations (AnnotationGx) OR contain metadata from authors? (Note: There can be common columns like drug or cell identifiers - Which one should be kept?)
