NAME

GOBO::LinkStatement

SYNOPSIS

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

DESCRIPTION

A type of GOBO::Statement that connects two GOBO::Node objects via a GOBO::RelationNode object.

Can also be thought of as an "edge" in an GOBO::Graph

LiteralStatements inherit the roles GOBO::Attributed and GOBO::Identified (via GOBO::Statement). This means they can have metadata attached. For example, who created the edge, when and why.

Subtypes

An important subtype of this class is GOBO::Annotation, which attaches evidence to edges.

This class could conceivably be extended to add accessors for distance etc for phylogenetic trees
