My Strengths & Biases

_ Conceiving and getting off the ground

large-scale, collaborative, ground-breaking

projects

_ Focus on technological approaches to visual

material

_ Work on making archival material

accessible through technology,

interoperability, standards

_ Bias towards non-bestseller content

My Impressions of MIAP

Program-

_ Caveats

_ Strengths

_ Cautions

_ Ideas









Besser--NYU 4/11/02 20

Critical Pieces currently in

MIAP program

_ History/Contextualization

_ Important underlying concepts (Collecting)

_ GEH

_ Working professionals teaching at GEH









Besser--NYU 4/11/02 21

Cautions-

_ High Level Concerns-

_ Small program size-

_ Guard against the students identifying too

closely with the GEH approach-

_ Extend principles beyond film-







Besser--NYU 4/11/02 22

Cautions:

High-level Concerns



_ Treading the line btwn Academic &

Professional

_ Need to be inclusive & collaborative to pull

this off well







Besser--NYU 4/11/02 23

Cautions:

Small Program Size



_ Necessary for apprenticeship, but problems

with:

– economic sustainability

– maintaining diversity of students

_ Possible answers

– grow out courses around it, particularly in new

media

Besser--NYU 4/11/02 24

Cautions:

Guard against the students

identifying too closely with the GEH

approach

_ Make sure that graduates will feel

comfortable going into collections that take

different approaches because they‟re:

– Smaller

– Poorer

– Have different collection scopes

– Less film-centric

– Not within museums

Besser--NYU 4/11/02 25

Cautions:

Extend principles beyond film

_ Core principles are similar for handling

video, digital “stocks”, but students need to

be able to distinguish where the principles

differ and where they remain the same

_ From an economic standpt, in future years,

there will be more jobs handling non-film

materials than materials on film stock



Besser--NYU 4/11/02 26

My suggestions

_ Expand high-level concepts (what is work?)

_ Strengthen understanding of underlying economics to

filmmaking and distribution (as well as that of video and

digital if you enter that arena)

_ Enlarge the scope to include video, digital works, new

media

_ Leverage other GEH depts (Education, Collctn Mgmt)

_ Increase the focus on info about the work-

_ Play to your strengths-





Besser--NYU 4/11/02 27

Increase the focus on info

about the work

_ Collectn Mgmt info, preservation record-keeping, etc.

_ Info that‟s far less format-dependent, so skills in this area

withstand the test of time

_ An important growth area in an age where people demand

higher levels of granularity in info about objects



_ Also, research potential w/I this area where NYU can

become int‟l leader (library extending METS, repositories

for shot-by-shot analysis, using semiology to develop

preservation encoding schemes, …)



Besser--NYU 4/11/02 28

Play to your strengths

_ Other repositories in NYC (Anthology, MOMA, Lincoln Cntr,

Kitchen, ...) & important vendors (VidPix)

_ Departmental strengths in independent and avant-garde works (and

NYC as vibrant cntr for these)

_ Academic rigor for examining and deconstructing underlying concepts

(why collect? what is a work? )

_ NYU Library strength in Preservation & in digital metadata

_ Incorporate dept strengths to bring new research to aid in in

preservation (ie. Semiological analysis to construct encoding standards

that will persist over time)

_ Collaborate w/NYC groups working on similar issues (from IMAP to

Guggenheim to Mellon)







Besser--NYU 4/11/02 29

Why focus on the

Orphan/Ephemeral/Experimental

Films?

_ These types of films are both more

interesting and more in peril

_ Best-sellers will be taken care of (for better

or worse) because of market potential

_ These pose more interesting research

questions

_ You‟re not USC



Besser--NYU 4/11/02 30

Future

Orphan/Ephemeral/Experimental

Films will not be on film stock

_ Economics is making film stock and editing

increasingly out of reach for independent

filmmakers

_ Focus is on newer creation formats (video,

digital, multimedia)

_ And digital distribution channels appear to

make it easier to get to audiences



Besser--NYU 4/11/02 31

In the future, most interesting works

will involve digital technology



_ “Once computers become married with

film, the form becomes promiscuous, and

that can bring about new ways of making

movies that the studios can‟t control.”

-Francis Coppola

LA Times, April 7, 2002

Press Play to Access the Future

copy

– Increasingly no paper back-up at all

– Usually we don‟t have the important redundancy factor



_ Mellon funded projects (2001)

– Yale, Harvard, Penn working w/individual publishers

– Cornell, NYPL--specific disciplines

– MIT exploring characteristics that change (dynamic)\

Electronic Resource Preservation

and Access NETwork (ERPANET)

_ Best practices and skills development for

digital preservation of cultural heritage and

scientific objects

_ 3 year project launched Nov 2001; 1.2

million Euros









Besser--NYU 4/11/02 39

NEA 2001 grant to BAVC

for $150,000

_ “To support development and dissemination

of a DVD that contains a curriculum for the

preservation of electronic art. The DVD will

feature a preservation overview; discussions

with conservators, artists, curators and

technicians; a curriculum to train

professionals in the field and project case

studies to conserve electronic art.”

Besser--NYU 4/11/02 40

Digital Preservation now has

high profile

_ Lots of money available

_ Interesting research questions

_ Communities begin to work together

_ Very little yet done with challenging

material like moving images and electronic

art

_ NYU could become leader in this arena

My research into Digital

Preservation









Besser--NYU 4/11/02 42

Preserving New Media:

What‟s the problem & What can we do

about it?

_ The Problem: Maintaining Accessibility to a Work over time

_ New Products and New Expectations necessitate New Paradigms

_ The Easy Part of the Problem: Physical storage devices &

hardware players

_ The Hard Part of the Problem: File Formats

_ Problems with Many Types of Digital Works Today

_ Special Characteristics of Electronic Works

_ What is the Work?

_ Some approaches to solutions







Besser--NYU 4/11/02 43

The Problem:

Maintaining Accessibility to a

Work over time



_ Preservation techniques for Physical

artifacts do NOT address the problem of

preserving digital works



_ Need to shift from preserving Physical

Artifact to preserving disembodied content

Besser--NYU 4/11/02 44

Digital Cinema is not like canvas

paintings

_ In the future these may include

– Moving image materials

– Multimedia

– Interactive programs

– Computer generated art

_ These works share some common characteristics

with other “strange” works like

– Performance Art

– Conceptual Art

– Site-specific installations

– Experiential Art

Besser--NYU 4/11/02 45

Thinking of the Future (1/2)

_ Screens will be different resolutions and

different aspect ratios

_ CRTs won‟t exist

_ A decade or 2 from now, today‟s user

interfaces will look like arrow-key

navigation looks like today





Besser--NYU 4/11/02 46

Thinking of the Future (2/2)

_ Today‟s streaming media are small

windows, slow speeds

_ As bandwidth increases, viewers will expect

higher quality streams

_ Artists may need to consider how they‟ll be

able to deliver higher-bandwidth streams

– Delivery Derivatives vs. Masters encoded w/standards

– May also want to re-edit the piece to take advantage of

changes in technology, viewer expectations, society-

Besser--NYU 4/11/02 47

New products & Shifts in user

expectations

_ VCR led to user expectation of time-shifting,

which in turn created market for video-on-demand

and cinema multiplexes with staggered times

_ WWW will further increase expectation of

immediacy, as well as:

– viewing massive amounts of related materials

– viewing material in fragmented ways

_ DVDs are even further increasing need for

ancillary materials, as well as for interactivity and

viewing fragments

Besser--NYU 4/11/02 48

Key Paradigm Shifts for

Museums/Archives

(also implications for artists)



_ From archiving completed whole works to

asset mgmt of both component parts of

works and ancillary materials related to the

work

_ From preserving a physical artifact to

saving a digital work that has no tangible

embodiment

Besser--NYU 4/11/02 49

Component Parts & Ancillary

Materials

_ Edit decision list

_ Out-takes

_ Special effects

_ Initial casting calls

_ Sketches of sets

_ Interviews

_ Scripts...





_ If the Archivists don‟t act to save these, their role will be marginalized. Need

to poractively seek out material that may be routinely tossed out.

_ These materials may become important for either re-issuing the piece in a later

version, or for future curators trying to understand the artist‟s intention enough

to re-display the piece when all the software used is no longer available.

Problems with Many Types of

Digital Works Today-

 Disappearing Information

 The Viewing Problem

 The Scrambling Problem

 The Inter-relation Problem

 The Custodial Problem

 The Translation Problem





Besser--NYU 4/11/02 65

The Viewing Problem

 Digital Info requires a whole infrastructure

to view it

 Each piece of that infrastructure is changing

at an incredibly rapid rate

 How can we ever hope to deal with all the

permutations and combinations





Besser--NYU 4/11/02 66

The Inter-relation Problem

 -Info is increasingly inter-related to other

info

 -How do we make our own Info persist

when it points to and integrates with Info

owned by others?

 -What is the boundary of a set of

information (or even of a digital object)?



Besser--NYU 4/11/02 67

The Translation Problem

 Content translated into new delivery devices

changes meaning

– -A photo vs. a painting

– -If Info is produced originally in digital form in

one encoded format, will it be the same when

translated into another format?

– Behaviors





Besser--NYU 4/11/02 68

Conceptual Approaches to

Digital Preservation

_ Refreshing always necessary due to

volatility of physical strata

– Impact on evidential value

_ Migration -- advantages & disadvantages

_ Emulation -- advantages & disadvantages

Special Characteristics of

Electronic Works

_ What Really is the Work?-

_ Disappearing software

_ Enormous number of elements can, at times, be very important to

preserve (randomness, interactivity, pacing, color, format, original

artifact, elements used to construct the artifact)

_ Pieces and Boundaries

_ Recontextualization (Postmodernism)--which rendition to save?

_ Dynamic & Lack of Fixity (evolving works)

_ Historical context

_ Difficulty of authentication over time

Special Characteristics of

Electronic Works (again)

_ What Really is the Work?-

_ Disappearing software

_ Enormous number of elements can, at times, be very important to

preserve (randomness, interactivity, pacing, color, format, original

artifact, elements used to construct the artifact)

_ Pieces and Boundaries

_ Recontextualization (Postmodernism)--which rendition to save?

_ Dynamic & Lack of Fixity (evolving works)

_ Historical context

_ Difficulty of authentication over time







Besser--NYU 4/11/02 86

Pieces of the General Solution

(1/2)



 -We need to insist upon clearly readable

standardized ways for digital objects to self-

identify their formats

 -We should discourage scrambling

 -We need to better understand information

inter-relates to other Info, and what

constitutes “boundaries” of Info objects



Besser--NYU 4/11/02 87

Pieces of the General Solution

(2/2)



 -People and organizations wishing to make

information persist need guidelines of how

to go about doing it

 -We need to better understand how

translating from one storage or display

format to another affects the meaning of a

work

 -We need to save the “behaviors” of a

digital object, not just it‟s “contents”

Besser--NYU 4/11/02 88

Metadata & Standards can be

the first line of defense

 Can tell you

– where the file is (if you can‟t find the file)

– where more info about the file is (if you have

the file but most other metadata has become

separated)

– what the file format is

– what the compression scheme is

– what application program and version is needed

for the file

Besser--NYU 4/11/02 89

From the technological point of view:



Standards offer the best hope

of overcoming Impediments

_ Easier to maintain a single set of standards

over long periods of time

_ Puts your institution in the same large boat

with lots of other institutions who will face

obsolescence and migration problems

periodically throughout the future





Besser--NYU 4/11/02 90

What can we do specific to

New Media?

_ Works themselves may no longer even exist; in many cases, what we

can save amounts to forensic evidence

_ Enormous number of elements can, at times, be very important to

preserve (pacing, original artifact, elements used to construct the

artifact)

_ Too complex to save every one of these aspects for every type of

material

_ Importance of saving pieces, representations, and documentation

_ Involve the artists to capture their intentions

_ Importance of Standards

_ Familiarize ourselves with recent conservation developments

(Guggenheim‟s Variable Media, Who Knows?, TechArcheology, Tate,

IMAP)-

Besser--NYU 4/11/02 91

Standards for encoding

artists intentions

(group efforts)





_ Guggenheim‟s Variable Media project

_ Artists Interviews Project, Netherlands Institute

for Cultural Heritage 1998-1999, Modern Art:

Who Cares (http://www.icn.nl/english/6.4.2.html)

_ TechArcheology: A Symposium on Installation

Preservation (SFMOMA)

_ IMAP

Besser--NYU 4/11/02 92

Authors Intentions: Kendall Example









Besser--NYU 4/11/02 93

Standards for encoding

artists intentions

(possible ways to proceed)





_ initially probably a few fixed fields and a lengthy

open field (similar to Technical Imaging Standards

for “reformatting intention”

_ should identify certain types of info that should be

only for museum personnel, some for general

public viewing, and others unknown





Besser--NYU 4/11/02 94

Things that can be done

_ Save documentation about the work and its

context

_ Save interviews with readers/viewers about the

experience

_ Construct repositories that save software, works,

hardware, and engage in ongoing emulation

_ Encode authors intentions-

_ Adhere to non-proprietary software/standards as

much as possible-

Besser--NYU 4/11/02 95

Tensions around Standards



Follow Standards (No Owl, Hypercard, DHTML, Flash, …)









_ innovative, new functions

Besser--NYU 4/11/02 96

Structural Metadata Standards

for Encoding Multimedia-

_ SMIL

_ MPEG 4









Besser--NYU 4/11/02 97

Synchronized Multimedia

Integration Language (SMIL)

_ For repurposing and reuse in different ways

_ Use XML to reference various pieces in different

ways

_ Supported by Realmedia but not Microsoft or

Macromedia









Besser--NYU 4/11/02 98

MPEG 4

_ Object-oriented

_ Very low level of granularity (even objects vs

backgrounds)

_ Scaleable bandwidth use

_ Binary Format for Scenes (BIFS) borrows

concepts from VRML









Besser--NYU 4/11/02 99

Saving Ancillary Materials









Besser--NYU 4/11/02 100

Concluding Remarks

_ Use Standards wherever possible

_ Be aggressive about asset mgmt -- saving

component parts and ancillary materials

_ Both Artist and Museum should develop an

institution-wide plan for saving electronic works

– Refreshing and either migration or emulation

– Standard encoding schemes

– What is the work? And prioritize what needs to be

saved

– Save ancillary materials and records

Besser--NYU 4/11/02 119

Persistent IDs--the Problem

_ Need to separate work ID from work

_ URNs probably won‟t be ready until 2003

_ Becomes a business process issue when one

organization maintains the resource and

another organization references it (ie.

licensed from vendors or managed by

separate administrative structures)

Besser--NYU 4/11/02 120

More Persistent IDs

--the Approach for today

_ PURLs

_ Handles

_ HTTP redirects



_ And worry about costs now and conversion

costs when URNs become feasible





Besser--NYU 4/11/02 121

Website Management

More issues with referencing IDs

_ References for mirror sites
