Query Language for Phylogenies/Clade Definition Notation

[keesey]

I posted a draft of a phylogenetic query language here: http://namesonnodes.org/ns/math/2009/query.html

Some examples:

Code: Select all

"Aves" := clade("Struthio camelus" | "Tetrao major" | "Vultur gryphus").

"Saurischia" := clade("Megalosaurus bucklandii" <- "Iguanodon bernissartensis").

"Avialae" := clade("wings used for powered flight" @ "Vultur gryphus").

"Ichthyornithes" := clade("YPM-VP 1450" <- "Struthio camelus" | "Tetrao major" | "Vultur gryphus").

"Ichthyornis" := clade("Ichthyornithes" & ("apomorphy 2" | "apomorphy 5" | "apomorphy 6" | "apomorphy 7" | "apomorphy 8" @ "YPM-VP 1450"))

"Pan-Biota" := (clade * prc&)("Homo sapiens").

"S" := "Otaria byronia" | "Odobenus rosmarus" | "Phoca vitulina".
"Pinnipedia" := (max * prc&)("S") <= ("flippers" @ "S") ? clade("S") : {}.

Still working on it -- would greatly appreciate feedback.
