ia and comes with many assumptions about the kind of connections and
practices that are desirable. We wanted to work with Semantic extensions specifically
because we were interested in the way The Semantic Web[7] seemed to resemble Otlet's
Universal Decimal Classification system. At many moments we felt ourselves going down
rabbit-holes of universal completeness, endless categorisation and nauseas of scale. It made
the work at times uncomfortable, messy and unruly, but it allowed us to do the work of

egion alone. They also
indicate how party politics is increasingly confined to the periphery of other forms of power

The Universal Decimal Classification[21] system, developed by Paul Otlet and Henri
Lafontaine on the basis of the Dewey Decimal Classification system is still considered one of
their most important realizations as well as a corner-stone in Otlet's overall vision. Its
adoption, revision and use until today demonstrate a thoughtful and successful approach to

act express whole sentences and
statements in UDC format[22]. The fundamental idea behind it [23]was that books and
documentation could be broken down into their constitutive sentences and boiled down to a
set of universal concepts, regulated by the decimal system. This would allow to express
objective truths in a numerical language, fostering international exchange beyond translation,
making science's work easier by regulating knowledge with numbers. We have to understand
the idea in the time it was originally conceived, a time shaped by positivism and the belief in
the unhindered potential of science to obtain objective universal knowledge. Today,
especially when we take into account the arbitrariness of the decimal structure, it sounds
doubtful, if not preposterous.
However, the linguistic-numeric element of UDC which enables to express fundamental
meanings through numbers, plays a key role in the oeuvre of Paul Otlet. In his work we learn
that numerical knowle

emergence and development of the internet is taking place precisely at the point at which an institutional

to choose a universal
classification and to recommend it as such in the
same way that the French Convention recognized
the necessity of a universal system of weights and
measures. In 1895 the first International Conference
of Bibliography chose the Decimal Classification
and adopted a complete plan for its development. In
1904, the edition of the expanded tables appeared. A
new edition was being prepared when the war broke
out Brussels, headquarters of the International Institute of Bibliography, which was doing this work,
was part of the invaded territory.
In its latest state, the Decimal Classification has
become an instrument of great precision which
can meet many needs. The printed tables contain
33,000 divisions and they have an alphabetical index consisting of about 38,000 words. Learning is
here represented in its entire sweep:

with the complex expressions which one finds in the modern terminology of disciplines like medicine, technology,
and the social sciences. Above all, it is impossible
to achieve any international cooperation on such
a national basis as language. The Decimal Classification is a vast systematization of knowledge, “the

treatises. But, as it would be impossible to find a
particular subject’s relative place by reference to
another subject, a system of numbering is needed.
This is decimal, which an example will make clear.
Optical Physiology would be classified thus:
5 th Class
3rd Group
5th Division
7th Sub-division

Natural Sciences
Optical Physiology

or 535.7
This number 535.7 is called decimal because all
knowledge is taken as one of which each science is
a fraction and each individual subject is a decimal
subdivided to a lesser or greater degree. For the sake
of abbreviation, the zero of the complete number,
which would be 0.5357, has been suppressed because
the zero would be repeated in front of each number.
The numbers 5, 3, 5, 7 (which one could ca

rty-five point seven and which could
be arranged in blocks of three as for the telephone,
or in groups of twos) form a single number when
the implied words, “class, group, division and subdivision,” are uttered.
The classification is also called decimal because
all subjects are divided into ten classes, then each
of these into at least ten groups, and each group
into at least ten divisions. All that is needed for the
number 535.7 always to have the same meaning is
to translate the tables into all languages. All that is
needed to deal with future scientific developments

in optical physiology in all of its ramifications is to
subdivide this number by further decimal numbers
corresponding to the subdivisions of the subject
Finally, all that is needed to ensure that any document or item pertaining to optical physiology finds
its place within the sum total of scientific subjects
is to write this number on it In the alphabetic index
to the tables references are made from each word
to the classification number just as the index of a
book refers to page numbers.
This first remarkable principle of the decimal
classification is generally understood. Its second,
which has been introduced more recently, is less
well known: the combination of various classification numbers whenever there is some utility in expressing a compound or complex heading. In the

more concrete, but no less ambitious terms, the Mundaneum was to gather
together all the world’s knowledge and classify it according to a universal
system they developed called the “Universal Decimal Classification.” In 1910,
Otlet and Fontaine found a place for their work in the Palais du
Cinquantenaire, a government building in Brussels. Later, Otlet commissioned
Le Corbusier to design a building for the Mundaneum in Geneva. The cooperation

between the cultural functions of libraries and the commercial interests that

Dewey, inventor of the Dewey Decimal System, was a great admirer of the
corporate ideal, and was eager to apply it to the library system.56 Indeed,
library development in the United States was greatly advanced by the
philanthropy of capitalism, most notably by Andrew Carnegie.57 The que
