This class is an abstract class from which all MAGE-TAB Material
classes (Source, Sample, Extract, LabeledExtract) are derived. It
cannot be instantiated directly. See the Node class for
The name of the material (data type: String).
The type of the material (e.g. whole_organism, organism_part,

A free-text description of the material. In general the use of this
attribute is discouraged due to the difficulty of computationally
parsing natural languages (data type: String).
A list of characteristics of the material. These may describe any
aspect of the material, and should ideally be taken from an
appropriate ontology (data type: Bio::MAGETAB::ControlledTerm).
A list of measurements of the material. These may describe any
measurable property of the material. Units are handled by the
Measurement class (data type: Bio::MAGETAB::Measurement).
Each attribute has accessor (get_*) and mutator (set_*) methods, and

relationship the mutator accepts an arrayref and the accessor returns
