1. Change request: add cell_line class inherited from sample (cell_line class would need an ATCC number and type)
- Solution: users who need cell_line should extend from FuGE::Material directly
2. Change request: add anatomic_part class inherited from sample
- Solution: anatomic_part information can be described with ontology terms. It may not be necessary to explicitly add it in current FuGEFlow model
3. Change request: remove sample type
- Solution: sample type removed as type can be inherited from FuGE::Material
4. Change request: phenotype and genotype inherited from ExternalData
- Solution: done
Issues unclear:
a) Can the Factor class can be used here to describe treatment agents?
b) How to make the class structure scalable so that users can extend FuGEFlow themselves when they cannot find enough placeholders?
