Description
Notes
iuipThe IUI that designates the particular that is the subject of this template 
iuiaThe IUI that designates the author of this template 
taThe IUI that designates the temporal region at which this PtoDE assertion was made 
rThe relation that holds between the particular denoted by iuip and the universal denoted by uuiMostly we just use is concretized by. Not clear what other relations would be appropriate, but we maintain the flexibility nonetheless.
deThe digital entity itselfMostly we'll just have strings here (probably UTF-8 or ASCII or in case of Mac some other encoding)
uuiThe UUI that designates the universal to which the particular is relatedTypically a Uniform Resource Identifier (URI) from an OWL ontology. But not necessary. It would say whether the encoding is Unicode (and even then UTF-8 or UTF-16), ASCII, big or little endian double/float, integer, long, etc.
iuioThe IUI of the ontology from which uui and inst were obtainedIncreasingly, this parameter seems irrelevant. Although MIREOT allows that a given URI for a universal could come from any number of ontologies, it is not clear that it is valuable to say which one it came from specifically. Furthermore, we might have taken the relation (inst) and uui from different ontologies. It is not clear how to handle that situation either.
trThe temporal region during which the relation r holds between the particular (iuip) and universal (uui)It is not entirely clear with this temporal region would be. The fact that someone's name is concretized as "William Hogan" would hold from the time that that name for the person began to exist, typically at or shortly after birth. But then the name outlives the individual, so this temporal region would be different than the interval occpied by the person's history, although both intervals would have the same left boundary.
iuitThe IUI of the template itselfEvery template gets an IUI that is referenced minimally by one metadata template.
