# GO::Parsers::go\_xref\_parser(3pm)

## NAME

```
  GO::Parsers::go_xref_parser     - syntax parsing of GO xref flat files (eg eg2go, metacyc2go)
```

## SYNOPSIS

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

## DESCRIPTION

This generates Stag event streams from one of the various GO flat file formats (ontology, defs, xref, associations). See GO::Parser for details

Examples of these files can be found at http://www.geneontology.org

A description of the event streams generated follows; Stag or an XML handler can be used to catch these events

## GO XREF FILES

These files have a filename \*2go; eg metacyc2go

```
  (dbxrefs
   (termdbxref+
     (termacc "s")
     (dbxref
       (xref_dbname "s")
       (xref_key "s"))))
```
