22 Post-composition
Conclusions Gene to phenotype annotation tends to use a surgical or anatomical perspective – but does not directly include mechanism or causes By including cell and protein level annotations, causes and mechanisms are more explicit Post-composition enables more flexible annotation. But it is more difficult for annotators. The two strategies can be combined, but some post- composition seems necessary for multiscale and development research In development, we can’t ignore the structure of cells For multiple scales, there are too many combinations to pre-compose them all Lightweight reference ontologies are more manageable, but repositories of post-composed annotations are more challenging for reasoning
