NAME

         GO::Parsers::go_assoc_parser     - syntax parsing of GO gene-association flat files

SYNOPSIS

DESCRIPTION

       do not use this class directly; use GO::Parser

       This generates Stag/XML event streams from GO association files.  Examples of these files
       can be found at http://www.geneontology.org, an example of lines from an association file:

       See <http://www.godatabase.org/dev/xml/dtd/go_assoc-parser-events.dtd> For the DTD of the
       event stream that is generated

       The following stag-schema describes the events that are generated in parsing an assoc
       file:

         (assocs
          (dbset+
            (proddb "s")
            (prod+
              (prodacc "s")
              (prodsymbol "s")
              (prodtype "s")
              (prodtaxa "i")
              (assoc+
                (assocdate "i")
                (source_db "s")
                (termacc "s")
                (is_not "i")
                (aspect "s")
                (evidence+
                  (evcode "s")
                  (ref "s"))))))
