10/28/99Besser & Yamashita--EDUCAUSE 99 10 Cost Assessment Methodology MESL Technical Report Questionnaire –primarily voluntary self-reporting Clarifications and follow-up questions from Berkeley researchers Data Analysis by Berkeley researchers
11
10/28/99Besser & Yamashita--EDUCAUSE 99 11 MANAGED IMAGE (volume) Unique characteristics for “objects” in an open or shared user environment Consists of a formal association of multiple data elements Allows the volume to be accessed (“shared”) by multiple users CRITICAL element is “MANAGED” not “image”
12
10/28/99Besser & Yamashita--EDUCAUSE 99 12 MESL: BASIC DISTRIBUTION FORMULA Protect Copyright Control user access to the data Insertion of a security component

10/28/99Besser & Yamashita--EDUCAUSE 99 24 SUMMARY observations
25
10/28/99Besser & Yamashita--EDUCAUSE 99 25 University Infrastructure Costs High speed networks Classroom projection Workstation labs Workstations Costs must be spread across the entire campus
26
10/28/99Besser & Yamashita--EDUCAUSE 99 26 University Issues More technology resources for Humanities departments Faculty need incentives to teach with digital images Resources and tools are needed to making teaching with digital images less difficult Universities need to make digital projects a priority and need to find funding to carry them out
27
10/28/99Besser & Yamashita--EDUCAUSE 99 27 Security Universities can exercise sufficient control over initial access to image Museums may want more sophisticated protection to prevent copying and reposting
28
10/28/99Besser & Yamashita--EDUCAUSE 99 28 Metadata posed more of a problem than images –Mapping fields –Different vocabularies Integration of records from different museums
29
10/28/99Besser & Yamashita--EDUCAUSE 99 29 Some General Observations: Do costs diminish in subsequent years? Technology is changing so fast that development done just a year before can be obsolete Costs increase in 2nd year both because year #1 deployment exposed all the interesting things that one might like to do, and because increased size and use necessitated increased security One site estimated that their lower year #2 costs were 60% due to learning curve and 40% due to availability of better (imaging) software
30
10/28/99Besser & Yamashita--EDUCAUSE 99 30 Examining Faculty & Student Use & Usefulness What Faculty Do with Digital Images Major Issues for Faculty Faculty Concerns about teaching with Digital Images Faculty Concerns about Image Quality and Metadata
31
10/28/99Besser & Yamashita--EDUCAUSE 99 31 Comparing User Interfaces Presentation and layout Search options Image display and labeling
32
10/28/99Besser & Yamashita--EDUCAUSE 99 32 Findings -
33
10/28/99Besser & Yamashita--EDUCAUSE 99 33 Digital Distribution is: Good for individual usage Problematic for group viewing
34
10/28/99Besser & Yamashita--EDUCAUSE 99 34 Content Issues Selection will be museum-driven (MESL content selection won’t scale up) Sufficient critical mass? All the appropriate images needed to teach? Transparent integration with locally- mounted images and those from other sources?
35
10/28/99Besser & Yamashita--EDUCAUSE 99 35 Query and Use Users will want more than just query options Centralized development of searching, user interface, and tools is much more cost effective than than local development Local development can be more quickly responsive to local needs
36
10/28/99Besser & Yamashita--EDUCAUSE 99 36 Storage & Bandwidth Technological advances make this less of an impediment May still cause bottlenecks in centralized delivery systems
37
10/28/99Besser & Yamashita--EDUCAUSE 99 37 Universities and Museums MESL showed that universities and museums have common interests in providing images and metadata to users Will need to address issues arising when faculty produce new information built on museum information –enhanced content flowing back to the museum –distribution of faculty added-value products
38
10/28/99Besser & Yamashita--EDUCAUSE 99 38 New Audiences Potential for outreach to new constituencies within the university community, and new communities outside the university New audiences may have very different types of needs –most audiences won’t be able to decipher curatorial language –K-12 audiences will need added value of thematic arrangements
39
10/28/99Besser & Yamashita--EDUCAUSE 99 39 Copyright Issues In flux Too many unknowns Very problematic for 20th century works
40
10/28/99Besser & Yamashita--EDUCAUSE 99 40 Value of Museum Info to Universities Likely more in authoritative metadata than in images alone
41
10/28/99Besser & Yamashita--EDUCAUSE 99 41 EXISTING INFRASTRUCTURE: analog slide libraries
42
10/28/99Besser & Yamashita--EDUCAUSE 99 42 Centralized delivery to users & local mounting How to transparently integrate both?
43
10/28/99Besser & Yamashita--EDUCAUSE 99 43 ANALOG DISTRIBUTION PATH Bottom-up distribution model (PULL model - content on demand) Driven by users and usage (presumes fair use) Focus on servicing user base
44
10/28/99Besser & Yamashita--EDUCAUSE 99 44 Analog Slide Libraries + Perform valuable services that a centrally- supplied source reliably can’t Customized for local needs (coverage, metadata, vocabulary) Rapid response to local needs Departmentally funded (in contrast to likely funding of centrally-supplied information) Average size - 280,000 images
45
10/28/99Besser & Yamashita--EDUCAUSE 99 45 Coexistence of Analog and Digital Many years before we reach a critical mass in digital form Many more years before we’ll have the right images to teach with Instructors will draw on both slide libraries and digital collections But how will universities financially support both? Responsibility for digital collections is likely to rest within a campuswide unit (not a departmental one)
46
10/28/99Besser & Yamashita--EDUCAUSE 99 46 Costs Digital distribution under MESL was expensive Costs will decline from learning curves and new technological tools Cost will increase with each change to new technologies Per-image infrastructure costs will decline as fixed costs are spread over a larger number of images New costs will arise as the scope of the project increases –security becomes more of an issue Digital distribution has the potential to reach far more potential users than an analog system
47
10/28/99Besser & Yamashita--EDUCAUSE 99 47 Conflicting Needs University administrators want to control costs; faculty want to ensure continued access to the images around which they build curricula Museum delivery systems will need an ongoing revenue stream
48
10/28/99Besser & Yamashita--EDUCAUSE 99 48 Similar Needs Both universities and museums own content Both universities and museums extensively use images in carrying out their mission Universities and museums have more in common than differences
49
10/28/99Besser & Yamashita--EDUCAUSE 99 49 CONCLUSIONS
50
10/28/99Besser & Yamashita--EDUCAUSE 99 50 Some Concluding Remarks on the Study Authoritative museum information has great value to universities University infrastructure costs for image delivery are very large, and cannot be justified solely for cultural heritage Greatest savings for universities are likely to come from digital delivery of authoritative descriptive information about the image The university market does not have enough resources to financially sustain the costs of a museum consortium’s digital distribution system, and such a system must be subsidized by the museums or from external sources.
51
10/28/99Besser & Yamashita--EDUCAUSE 99 51 Further Study questions Will digital distribution replace slide libraries? Will target groups use digitally distributed images? Who in the University will contract for digital image distribution rights?
52
10/28/99Besser & Yamashita--EDUCAUSE 99 52 Future Research Examine real operational systems How to integrate information from a remote source with locally mounted information What do faculty need in order to begin widespread teaching with digital images? How will teaching change as digital image resources become more available? What kind of additional tools will users need? How will the different vocabularies used by museums be integrated for user access? What standards will be needed, and how will the right parties be brought together? Pedagogy of using online resources
53
10/28/99Besser & Yamashita--EDUCAUSE 99 53 Observations about Study Design Studying prototypes, experiments, early stage, etc. is very difficult –staff overworked and touchy –who performs what function is ad hoc –does not really resemble a production environment Studying complex and/or hetrogenous organizations creates problems –units of measurement –parallel workflows Studying Digital Libraries will be difficult (at least in the early stages -- when it’s most needed)
