An Object is an atom with a set of properties. This corresponds to an RDF Resource, and can be thought of as a dictionary with URID keys.

This is an abstract Atom type, an Object is always either a atom:Resource -or a atom:Blank.

Code SHOULD check for objects using lv2_atom_forge_is_object() or +lv2_atom_forge_is_blank() if a forge is available, rather than checking the +atom type directly. This will correctly handle the deprecated atom:Resource +and atom:Blank types.
