NeXML is a file format for phylogenetic data. It is inspired by the modular architecture of the commonly-used NEXUS file format (hence the name) in that a NeXML instance document can contain:
sets of Operational Taxonomic Units (OTUs), i.e. the tips in phylogenetic trees, and that which comparative observations are made on. Often these are species (“taxa”).
sets of phylogenetic trees (or reticulate trees, i.e. networks)
sets of comparative data, i.e. molecular sequences, morphological categorical data, continuous data, and other types.
The elements in a NeXML document can be annotated using RDFa (en.wikipedia.org/wiki/RDFa), which means that every object that can be parsed out of a NeXML document must be an object that, in turn, can be annotated with predicates (and their namespaces) and other objects (with, perhaps, their own namespaces). The advantage over previous file formats is that we can retain all metadata for all objects within one file, regardless where the metadata come from.
NeXML can be transformed to RDF using an XSL stylesheet. As such, NeXML forms an intermediate format between traditional flat file formats (with predictable structure but no semantics) and RDF (with loose structure, but lots of semantics) that is both easy to work with, yet ready for the Semantic Web.

It is not complete, but definitely enough to get started.
Contributing to bio-nexml
Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it

Commit and push until you are happy with your contribution
Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
