The cite library can extract the required top-level components of a CITE URN.
The top level components of the URN urn:cite:hmt:msA.12r are:
The cite library can determine what optional parts of the object component are present, and can extract them from the object component if they exist.
The URN urn:cite:hmt:msA.12r :
The URN urn:cite:hmt:vaimg.VA012RN_0013.v1@0.1532,0.1021,0.4014,0.0225:
Because the components of a CITE Object URN have specified semantics, we can work with semantically meaningful manipulations of a CITE Object URN.
Every CITE URN has an object component minimally composed of a collection identifier, so we can always reduce a CITE URN to a URN identifying its collection.
Similarly, we can determine whether a CITE URN has an extended reference component, and if so we can reduce a CITE URN with extended reference to a URN identifying the unique object without extended reference.
The URN urn:cite:hmt:msA.12r belongs to the collection identified by the URN urn:cite:hmt:msA.
The URN urn:cite:hmt:vaimg.VA012RN_0013.v1@0.1532,0.1021,0.4014,0.0225 belongs to the collection identified by the URN urn:cite:hmt:vaimg.
