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

## NAME

```
  GO::Parsers::go_ont_parser     - syntax parsing of GO .ontology flat files
```

## 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 ONTOLOGY FILES

These files have the .ontology suffix. The stag-schema for the event streams generated look like this:

```
  (ontology
   (source
     (source_type "s")
     (source_path "s")
     (source_mtime "i"))
   (term+
     (id "s")
     (name "s")
     (is_root? "i")
     (relationship+
       (type "s")
       (to "s"))
     (dbxref*
       (dbname "s")
       (acc "s"))
     (synonym* "s")
     (secondaryid* "s")
     (is_obsolete? "i")))
```
