App/namespace

A namespace serves as space in which all the following identifiers are intended to (globally) identify unique things. The namespace plus identifier should be unique for all of the instances of the class the namespace is attached to. For example namespaces are used when barcodes are created where the barcode might be "AEI 0102312". Here AEI is the namespace, and we expect no more than one "specimen" to ever be identified with 012312. .

The Owner of the namespace is the person responsible for the uniqueness of the identifiers within it.
