]> Each OBO Term is uniquely identified by an Id, and its value is stored in this property. During conversion from a heirarchical, class-based representation, each OBO Term in the heirarchy is represented as a Term (or subclass of Term), and for each of these individuals, the id (e.g. GO:0006260 - dna replication in the gene ontology) is stored by an id property (or subproperty of id). Note that the URI of the Term individuals ends with the value of this property, with the colon character replaced with an underscore to result in a legal URI, since the colon character is reserved to indicate a port.
