Nexml Item Module Design (work in progress)


Currently, parsing a nexml file into Bioperl makes use of the *IO modules (AlignIO, SeqIO, and TreeIO) to load nexml represented data into bioperl objects. These modules will handle each data type separately, but the ultimate goal is to make this easier on the user and allow the full parsing of a nexml file with one pass of the Bio::Phylo parser without forcing the user to parse the file three times - once each for sequences, alignments, and trees. To accomplish this, a Bio::nexml module will be created that will act as a container for three different data types it contains. A powerful feature of nexml is it's ability to relate data to each other in relevant ways. This module will also maintain (as much as possible) the relationships between data.

Data Relationships to Maintain
