This document discusses the crucial role of file formats in preserving digital media cultures and their impact on society. It notes that while digital information is good because it can represent all kinds of information with bits, it is also bad because digital information locked in proprietary formats can become useless over time. The document advocates using open file formats to ensure long-term access to digital information and prevent "format wars" from destroying cultural works and attention.

● In this digital world, how do we preserve the possibility of
attention from the future?
● Are we making it possible for future generations (or even to
ourselves 10 years from now) to pay attention to our digital
works?
● How do we keep or exchange attention across social classes and
across opposite sides of the digital divide?
Speaking of generational responsibilities...

● Digital media cultures are rich and powerful, but also terribly
fragile
● Digital text or multimedia may be much more durable than house,
but very often isn't. Why?
● especially considering that it's infinitely copiable without degradation?
● Is this related to mechanical / electrical obsolescence, e.g. 5"
floppies or data tapes from the 80's unreadable because there are
no more drives for those objects around? NO!

● Software creates habits and relationships, that is culture
● We don't make up information just to use cool software. We
use software because we need to manage information.
Software is the intermediary between people, their own
digital documents and all kinds of services
● Technology (especially digital technology) is legislation
● What does this have to do with formats???
● Question: why do we change so many desktop computers every
few years, even if they are still perfectly working?
Social impact of digital technologies
6. Basic concepts and definitions
Q: How do we create, access and preserve information?
A: Thanks to three very different things:
Physical Support: the material object containing the information
Data Format: the rules by which the information is encoded on the support
User Interface: the tools used to write and read the data according to the format
almost always, Support, Format and Interface can (and should) be
independent from each other

7. Support, Format, Interface: analog electronic example
Support Format
Support and format are mixed here: Photograms can only
be impressed on a specific type of tape, in a way not usable
with other cameras and projectors
Interface
Camera and Projector that are
useless with any other tape
NOTE: this is the very popular Super 8mm home movie format, released on the market in
1965 by Eastman Kodak, not widely used since the 1980's

8. Support, Format, Interface: non electronic example
Interface
+
Any manual writing instrument
(don't forget quill and charcoal!)
and your eye!
Format
Hyeroglyphs (which could also
be written on paper, papyrus,
wood...) and the meanings
associated to each gliph
Support
The Rosetta
Stone,
II Century BC

9. Support, Format, Interface: digital, finally!
Support
Hard drives, floppies, CD
ROMs, DVDs, Compact
Flash drives... usable with
different hardware
They all contain the same
bits that can represent
wildly different types of
information: text, images,
audio...
Format
CHARACTER ENCODING:
the meaning associated to each bit
sequence:
EX: “01000001” means “A”
FILE FORMAT:
how each piece of data can and
must be stored and marked:
<style:properties style:columnwidth="1.785cm"/>
...
<table:table
cell><text:p>600000</text:p></table:tablecell>
+
Interface
Any software program aware of
the file format, regardless of :
the hardware it runs on: x86 or Apple
computer, cell phone, DVD player,
remote server...
Its license of use

10. Why is digital information good?
If all conceivable
kinds of
information (from
texts to music,
images and 3D
models) can be
represented as a
series of bits
We only need:
ONE class of generic storage devices: bit containers which can change shape and technology
without particular problems and are very cheap
ONE (ok, very large...) class of telecom networks, ie bit transporters
And all these data can be preserved or distributed with much less money, time and effort than before!

11. Why is digital information bad?
If all conceivable kinds of information (from texts to music, images and 3D models) can be represented as
bits sequences stored in bits containers, we have (at least) two big problems:
Bit containers are much more fragile than non-digital media: parchment lasts millennia, hard drives a few
years
This problem has a relatively easy solution (make many copies of information, refresh them
frequently) and is outside the scope of this seminar
The second problem is that, even when the container works perfectly, the sequences of bits are absolutely
useless if they are locked and we lose the key and cannot buy one:

● Software programs are pens, file formats are the
alphabets of the digital society
● Technically speaking, file formats can almost always be completely
separated from the specific software program(s) used to manage them
● If only truly open file formats are used, it doesn't matter if some pens
are very expensive and/or patented
● Would you tolerate pens that only allow to you write your notes and
letters with the font and language that the pen maker likes?
What are file formats?

● Keeping digital data and documents in proprietary formats can be
worst than not having them at all:
● it destroys or diverts (the possibility of) attention
● it creates even more digital divides
● Carelessness about formats transforms culture and (possibilities) of
paying attention
● People can only see, remember, use and understand, that is pay
attention, if digital documents and communications are in open
formats
Conclusions: pay attention to file formats

● Public document and services are increasingly managed through purely digital
data that can be published online at very low cost
● Open Data/Open Government may transform current states in active, really
participated democracy
● but only if all data are in plain sight in the right way everybody may quickly
offer public services, create wealth or "watch the watchmen"
● because public data presented in the wrong file format are almost useless since
they can't be QUICKLY processed or correlated
● E.G: a budget in PDF format instead of spreadsheet is much harder to validate
Oh, and what about (raw) data?

● Education to the role of file formats is necessary
● Only use open formats whenever it's possible
● Only use the right formats for each task
● (teach to) Go beyond "printed-pageness" and visual look of documents
(why waste more time on font or margins than on content, for text that
should be a Wiki page usable even on cell phones?)
● Teach to analyze and process data of public interests
● Oh, and of course: please, please, please...

● Refuse to use proprietary file formats in
Universities!!!!
● It creates discrimination between students that can afford the
hardware needed by closed formats
● All your work risks becoming unaccessible in a few years
● None of the problems above can be solved by software piracy
● It can be very bad PR for your University:

● This is necessary for both older and younger
people!
● "Web native" only means "born when the
WWW was already a mass-phaenomenon".
● It doesn't guarantee at all that a “Web native”
is also automatically Web savvy!
