## NAME

```
  GO::Model::Root - base class for all GO::Model objects
```

## DESCRIPTION

base class for all GO::Model objects

### new

WARNING: This procedure will die if initialization is unsuccessful.   Use an eval statement to catch such exceptions.

### obj\_factory

```
  Usage   - $obj->obj_factory->create_new_term_object($h);
  Alias   - apph
  Returns - L<GO::ObjFactory>
  Args    - none
```

### sprint\_self

Prints out a description of the object to a string.

### dump

dumps the object (can be read back in with eval)

### namespace

```
  Usage   - print $term->namespace();     # getting the type
  Usage   - $term->namespace("molecular_function"); # setting the type
  Alias   - type
  Alias   - term_type
  Alias   - category
  Alias   - ontology
  Returns - string representing type
  Args    - string represnting type [optional]
```

The OBO namespace for the GO::Model::Term or GO::Model::Relationship

### \_cleanup
