Quick note ahead of the main entry: New paper by István Mikó et al. 2015. Generating semantic phenotypes. Worth a careful read.
The innovative paper by Ramírez & Michalik (2014) made for (another) lively discussion last week. The paper is rich with ideas and densely presented, which motivated an attempt by us to enumerate the sequence of data production and analytical steps. Another interesting question is to what extent (and why!) the authors’ approach moves away from the prevalent multi-taxon phenotype ontology approach. For instance, statements like the following (page 642) depart from the prevalent OBO language:
“As the Spider Ontology arose to manage the morphological concepts used in phylogenetic datasets, it is natural that it incorporated much of the pre-processed homology correspondences on its structure and definitions, to make room for the variety of form and function that the same organ may have in different organisms. In this way, the ontology accommodates the vast majority of homology statements currently accepted in spider systematics.”
