Developed by the International DOI Foundation (IDF), the Digital Object Identifier (DOI) is an identification system for intellectual property in the digital environment. The IDF recently established a working group entitled Digital Object Identifier for e-Books (DOI-EB), the purpose of which is to:
Since commercial implementations of DOI will be an important focus of DOI-EB, the active participation of all parties in the value chain is welcomed.
Before seeking to apply unique identifiers to eBooks, one might first ask,
What exactly is an eBook? There are no covers, as it were, and the very
attributes of an eBook may make defining the term more difficult and less
precise. That no well-developed eBook market exists no doubt adds to the
difficulty in defining what we mean by
eBook. The term
well turn out primarily to be a marketing term, one that proves to be quite
inadequate in the long run because, ironically enough, the greatest potential
of eBooks is not to be books at all.
In spite of the obstacles, brave souls have attempted, not completely
successfully as yet, to define the term
eBook. Lest one conclude that I
cast stones from a glass house, let me make clear that I have been closely
associated with two of these efforts. The draft definition of the Electronic Book
Exchange Working Group (EBX)
indicates that an eBook may consist of a single page, and it also refers to
paper books to define electronic books. It needs work. A somewhat different
approach is taken by the Open eBook Forum (OeBF) that provides a draft
definition  that is appealing
because it refers to unique identifiers and metadata, although that may not be
strictly necessary. Further, neither it nor the EBX definition makes a
distinction between an abstraction of a work and a particular manifestation of
that work. Still a third definition is offered by ONIX which takes a
more subtle approach by describing three ebook entities.  Interestingly, and helpfully, the ONIX
approach separates content from presentation.
In grappling with the term
eBook we must also note that the focus of
ebook transactions, for the time being, will be on the initial sale and rights
associated with the initial sale.  The term
eBook serves an immediate marketing need in
that it handily identifies an opportunity many seem to understand. Yet, in the
long run, the very term
eBook may be a misnomer. As the marketing focus
shifts from the initial sale of an ebook to secondary uses and licenses
involving more detailed rights transactions, it is very possible that term
eBook may be much less useful than it appears to be at the moment. At
that point, we may need to speak of something other than eBooks, and only by
means of unique identifiers and associated metadata can these rights
transactions come to fruition in the market.
Merely selling eBooks to consumers does in fact not require
persistent, unique, and global intellectual property identifiers such as DOI.
Indeed, Barnes & Noble, Glassbook/Adobe, netLibrary, Microsoft, Digital
Goods and others sell eBooks on the web every day without such identifiers. However, few observers
particularly expect current eBook sales channels to generate significant
profit in the near term, and many, of whom I am one, suggest that selling or
licensing eBooks profitably may indeed require persistent, unique, and
global identifiers. Accordingly, we must focus not simply on discovery of
eBooks on the Internet but also on the exploration and exploitation of
profitable services that persistent, unique, and global identification of
intellectual property will facilitate along the entire eBook value chain. Such
a focus causes us to ask a second fundamental question,
What does it mean
to sell an eBook?
What one considers to be
selling an eBook may, in certain cases, be
licensing. I make the point here not for the purpose of legal analysis but to
explore commercial possibilities that unique identifiers for eBooks could
facilitate. Mere discovery of intellectual property entities does not inform
the commercial transaction one intends. Thus, we should consider what
commercial models or options should follow discovery. At least three factors
present themselves in exploring whether an eBook transaction is a sale or a
license: encryption technology, migration, and breaking an eBook into its
The first factor is encryption technology. Encryption technology generally comes part and parcel to the ebook. When one purchases a paper book, there is a notion of free transferability. That is to say, I can give the paper book to another or I may loan it. To the extent that encryption technology restricts the free transferability of the ebook, it has features that more closely resemble a license and not a sale. I am not suggesting that this must be so in every case, merely that this must considered in planning ebook businesses.
The second factor is migration. What happens when the format of my existing ebook becomes obsolete or a particular device manufacturer goes out of business and a format is not longer supported? Do I have the right to migrate the work to a successor format? Or must I purchase a new version? A sale is characterized by continuing access, as is the case with paper. If my access is not continuing, if I cannot migrate the work, the transaction takes on the characteristics of a license.
The final factor is breaking an eBook into its
parts. With a paper
book, if I consider the whole thing rubbish with the exception of Chapter 6, I
can remove Chapter 6 from the book, put it in my filing cabinet, and throw the
rest away. May I do so with an eBook? May I put it in my
cabinet? If not, the transaction takes on the characteristics of a license,
and not a sale. Might this also inform what eBook
parts need to be
It may not be necessary to detail every last branch of the tree to gain an understanding of the tree, as Mark Bide pointed out recently by way of analogy. Merely scoping out the trunk and major limbs will facilitate a greater understanding of the tree. Among the issues DOI-EB must explore are:

DRM begins upon creation and production workflow,according to an individual with whom we spoke. How DOIs need to get embedded in commercial workflows is of key interest.
saleablepieces? How are they identified?
Upon reviewing eBook wares shown at the 2000 Frankfurt Book Fair, one
observer claimed that,
the international publishing industry is coping with
a severe case of vertigo Much dizziness no doubt is due to the
wealth of opportunity before us. That no single vendor solution has yet
captured the attention of so young an industry is not particularly surprising.
That so many solutions focus on
electronic analogs of paper books,
however, is. Unique, persistent, and global identification of eBooks will
surely facilitate the greatest potential that eBooks have - not to be books at

 At the American Association of Publishers Professional and Scholarly Publishing (PSP) meeting in February 2000, Keiron Hylton, Managing Director at Berkery Noyes & Co. spoke of books (and journals incidentally) as no longer being free standing units of knowledge but as becoming mere points of access ? much like a web browser. Hylton speculated that such would be the case within ten years time, and his views ? which I find to be compelling - pose interesting challenges for those committed to thinking about eBooks as mere electronic analogs of paper books.

 The EBX draft defines an
eBook to be
a digital object that is an electronic representation of a
book. While an e-Book can consist of a single page, it is normally thought of
as an electronic analog of a multi-page hardcover or paperback book. An eBook
may exist in a variety of formats The Electronic Book Exchange

 The OeBF draft defines an e-Book as short for electronic book. 1. A Literary Work in the form of a Digital Object, consisting of one or more standard Unique Identifiers, metadata, and a Monographic body of content, intended to be published and accessed electronically. 2.

 This is not to disregard the many efforts currently under way that focus on more granular rights transactions. However, such efforts have captured neither imagination nor investment to the extent that eBook have.

 In conversation, October 2000.
 Eamonn Neylon and I conducted a series of initial discussions about DOI-EB with publishers and others in the value chain.
 Such an approach would be essential for a publisher who presented me outside the context of DOI-EB with the following issue. The publisher wanted to enable a professor to select from among chapters of their own books, as well as books of other publishers, to create custom eBooks online. The widespread commercialization of such an endeavor absolutely requires the application of metadata and unique identifiers to the underlying intellectual property at the necessary levels.
