NAME

GOBO::Statement

SYNOPSIS

printf '%s --[%s]--> %s', $s->node, $s->relation, $->target;

DESCRIPTION

A type of GOBO::Statement that connects an GOBO::Node object to another entity via a GOBO::RelationNode object. This can be thought of as a sentence or statement about a node.

In RDF and Chado terminology, the node can be thought of as the "subject", and the target the "object". The terms "subject" and "object" are avoided due to being overloaded.

The two subtypes are GOBO::LinkStatement (edges) or GOBO::LiteralStatement (tag-values). For most bio-ontologies, the Statements will be LinkStatements.

Statements have the roles GOBO::Attributed and GOBO::Identified. This means they can have metadata attached. For example, who made the statement and when.
