> We are going to add parsers for ISA-Tab data formats.
> ISA-Tab files are related to [ISA Tools|http://www.isa-tools.org/] which help to manage
an increasingly diverse set of life science, environmental and biomedical experiments that
employing one or a combination of technologies.
> The ISA tools are built upon _Investigation_, _Study_, and _Assay_ tabular format. Therefore,
ISA-Tab data format includes three types of file: Investigation file ({{a_xxxx.txt}}), Study
file ({{s_xxxx.txt}}), Assay file ({{a_xxxx.txt}}). These files are organized as [top-down
hierarchy|http://www.isa-tools.org/format/specification/]: An Investigation file includes
one or more Study files: each Study files includes one or more Assay files.
> Essentially, the Investigation files contains high-level information about the related
study, so it provides only metadata about ISA-Tab files.
> More details on file format specification are [available online|http://isatab.sourceforge.net/docs/ISA-TAB_release-candidate-1_v1.0_24nov08.pdf].
> The patch in attachment provides a preliminary version of ISA-Tab parsers (there are
three parsers; one parser for each ISA-Tab filetype):
> * {{ISATabInvestigationParser.java}}: parses Investigation files. It extracts only metadata.
> * {{ISATabStudyParser.java}}: parses Study files.
> * {{ISATabAssayParser.java}}: parses Assay files.
> The most important improvements are:
> * Combine these three parsers in order to parse an ISArchive
> * Provide a better mapping of both study and assay data on XHML. Currently, {{ISATabStudyParser}}
and {{ISATabAssayParser}} provide a naive mapping function relying on [Apache Commons CSV|https://commons.apache.org/proper/commons-csv/].
> Thanks for supporting me on this work [~chrismattmann].
