Thanks Vinod for the opportunity to comment. My concern was to make clear
the relevance of DOI and the Handle System's digital object architecture to managing physical items through the use of RFID. Since DOI is becoming widely used in libraries (CrossRef, DataCite, and other initiatives) and we have over 50 million already assigned, I thought it should be considered as a possible existing bridge between the world of some identifier schemes used in libraries and the world of digital networks (which RFID could communicate with through various mechanisms- we've been talking to some of the ITU folks
about this). Clearly the call as to whether this mentioned in the study
has to be yours but I wanted to mention it in case it had slipped by without being considered.
In brief: a DOI is an identifier of an object (of any type) on networks. It is NOT an identifier (only) of "Digital Objects". Hence e.g. a book may have a DOI (as well as an ISBN): see http://www.doi.org/factsheets/ISBN-A.html (and since a book may also have an RFID tag, the link is already clear). And other identifier schemes (which may or may not be of physical media or abstract entities) can be expressed in a DOI: see http://www.doi.org/factsheets/DOIIdentifiers.html . [Handle literature refers solely to "digital objects" but clearly any physical
object can be represented as a digital object - a sort of "avatar".]
Hence the Internet of Things lends itself to Handle applications. As ITU said last week, "The concept of connecting any kind of object to the Internet may be one of the biggest standardization challenges yet"
(http://www.itu.int/ITU-T/newslog/Internet+Of+Things+Standards+Work+Plan.asp
x ).
Since a Handle (DOI) can resolve to multiple data types, it is an ideal mechanism for maintaining links to current state data (i.e. values which may change over time) and other metadata for that item, i.e. interfacing RFID to the TCP/IP internet. It uses the Handle System (www.handle.net ) as its technical basis, a highly scalable and efficient way of placing managed pointers into a tag, and providing a highly scalable distributed dynamic registry.
I'm attaching some recent materials about the underlying technology; of course there is also more on our DOI web site at www.doi.org as well as at www.handle.net .
