Perhaps you could detail what you have in mind.
Do you mean binary encoding to the 64th bit (2 to the 64th)?
If so, you have a binary level as well.

The answer to the specific question is yes. What I have in mind is
the creation of a universal information access system based upon a code for
the unique identification of all recorded knowledge and information. I made
such a proposal in 1967 at a meeting in Tokyo of the 33rd Conference of FID
and International Congress on Documentation. With the change of one
word÷"future" to "present", the closing lines of my paper state my position
today. "As can be seen, the development of communications satellites and the
potential they have for keeping a world completely enveloped in the light of
knowledge hold a great promise for the future. It is a promise that should not
be denied by failure to adapt traditional principles to the problems of the
future. At the same time, it is imperative to recognize the mutual rights and
obligations that exist for both the creators and users of knowledge and
information."

The 64-bit numeric identifier could be applied to all public
information broadcast by satellite and to all private information. This
identifier would be one field and an alpha numeric code that would have 15
fields of information. In the following paragraphs, I will describe what I
have in mind for the numeric identifier.

If the 64th bit is a "1", then the numeric characters identify a public
digital object. If the 64th bit is a "0" and the 63rd bit is a "1", the
digital object is private or confidential. If the 62nd bit is a "1" and the
preceding two bits are "0" the numeric characters identify ephemeral events.
These could eventually include all TV programs. By activating these keys the
TV's could be turned on and tuned similar to the VCR + system today.

In use, every 64-bit numeric identifier would be evaluated. A shift key
would designate the interpretation as base 10 or 2. All calculations would be
made in binary with the following results, all identifiers with a total above
2.3 x 10X18 would be one of the three types of DOI's (digital object
identifier). Less than that, but more than 10X17 would be a geographic segment
identifier. Credit cards, smart cards, and other international documents for
transactions would have totals between 10X17 and 10X16. Totals below 10X16
would identify URL's, Universal Product Codes, telephone and other
communication devices, proper names and places, words and phrases in all
languages, and a special unicode page.
