Composite Annotation for Heart Development
Explore the intricate process of heart development through anatomy, tissue, cell, and protein perspectives. Discover pre-composition with GO and MP and post-composition with PATO and OPB, enhancing understanding of developmental mechanisms at multiple scales. Learn how gene-to-phenotype annotations benefit from cell and protein level insights, enabling a more comprehensive approach. Consider the challenges and advantages of post-composition in multiscale research, emphasizing the importance of cell structure in developmental studies. Acknowledge the contributions of researchers and delve into advanced modeling techniques for cardiac development.

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
