Specifications
for Projects Involving Digitization
(NOTE: changes from the original plan are added in red)
1. Describe
types of materials to be digitized (i.e., artifacts, maps, manuscripts,
photographs) and number of each:
10,000 transparencies and negatives, 800 text documents, 200 photographic
prints (b/w and color), 100 audiocassettes, 75 3/4 inch-U-Matic
videotapes, 25 1/2" VHS videotapes.
2. Identify
copyright issues and other potential restrictions;
X Public
domain X Permissions have been obtained
Permissions
to be requested - Plan to address: Most of the resources we will
select will be ones for which we hold copyright.
For some resources, we do not hold copyright but will obtain permissions
from the individuals who hold
copyright prior to digitization of the assets.
Privacy
concerns - Plan to address:
For some photographs, model releases were necessary and were obtained.
3. List the
equipment, with specifications, whether purchased, leased, or outsourced,
that will be used (e.g., camera, scanner, server):
We will outsource scanning of transparencies and negatives to a
professional photo-CD digital imaging service. For photo prints
we will use a professional-quality 12-bit gray/36-bit color-1200
x 1200 dpi scanner. For in-house audio and video digitizing, we
will use a 733 mHz G4 Mac w/Ultra 160 SCSI & internal DVD-R
drive; 21 " monitor; using Sound Edit Pro and DVD Studio Pro. As
needed to preserve deteriorating original material, we will either
outsource or rent Professional equipment with high-quality tape
transport mechanisms to derive the highest quality and to limit
degradation of original media. Storage systems: Access-level resources
will be stored on an HP Visualize NIT server or Network Attached
Server and backed up on DLT tapes. Master-level resources will be
stored on CDs and DVDs on a CD/DVD jukebox accessible over the network.
4. Specify each
type of file format (e.g., TIFF, JPEG) to be produced and anticipated
image quality of each (minimum resolution, depth, tone, pixels);

5. Describe
the quality control plan:
Our
in-house professional photographers will assess a sample of images
on the Kodak Photo-CDs using the quality control process and Image
Quality Assessment Survey from Kenney (1998)
http://www.
library.cornell.edu/preservation/kodak/kodak-appendices/form3. htm
In-house
media engineers will monitor
the quality of the audio and video transfer processto meet accepted
industry standards. Quality of indexing,
including creation and application of fixed vocabulary lists will
be overseen by our professional library staff.
The accuracy of historical information about individual resources
will be assessed by periodic gatherings of
senior and former museum staff,
6. Estimate cost
per image. Include costs such as scanning, quality control and indexing.
Indicate the basis for calculation:
Cost
per Image: $11.96
Single
images only. Assumes Indexer will spend .6 fte on images, Project
Director . I fte, Learning Tools Asst. 1fte, Media Asst 1 fte; hourly
rate includes fringe, Includes selection, preparation, scanning,
quality control, physical organization, creation of metadata, indexing.
Does not include project administration or MARC cataloging of collections
Utilized the RLG
Worksheet for Estimating Digital Reformatting Costs
www.rlg.org/preserv/RLG/preserv/RLGtools.html
7. Explain how
you will describe the content through metadata, including which
standard you will use (e.g., MARC, EAD, Dublin Core):
The Cumulus database will be used to index individual resources
(single images, pieces of exhibit graphics, raw sound and movie
footage.) Collections and other finished media resources (complete
speeches, Web resources, collections of images on a single topic)
will be cataloged into our online library catalog, Hypatia (library.exploratorium.edu)
using Bestseller (now BiblioMondo)
library automation software (www.
bestseller. com), MARC metadata standards and Library of Congress
Subject Headings. We will incorporate the Dublin Core standard into
the custornization of the Cumulus database, so that each of the
simple elements will have a corresponding field. Cumulus automatically
generates metadata on each resource that exceed the Dublin Core
standard. (Examples: color mode, image width, image height, horizontal
resolution.) Subject keywords will be taken from several fixed vocabulary
lists, including a collection of scientific phenomena terms originally
compiled by Frank Oppenheimer.
8.
Describe plans for preservation and maintenance of the digital files
after the expiration of the grant period (i.e., storage
systems, migration plans, and funding):
Digital
assets: Because we are using standard digital formats, and whenever
possible, preserving the original media,
transfer to future media formats should not pose a problem.
Preservation:
We will place one set of all digital files in the Bancroft Library's
archive of the Exploratorium. The Bancroft
catalogs its holdings into University of California at Berkeley's
online catalog, GLADIS.
Migration
strategies: Data in the Cumulus database is exportable to Filemaker
and can then be exported in a comma-delimited,
tab-delimited, SYLK, DBF,VVKS and BASIC formats, which will allow
us to import to other systems.
Funding:
The ongoing maintenance of the files will not add significant costs
to our existing Information Technology
budget.
9. If you are
producing collection-level records, describe plans for submitting
collection4evel descriptive records to a bibliographic utility,
such as Research Libraries Information Network (RLIN) or Online
Computer Library Center (OCLC). State reasons for selecting any
alternative approaches:
The Exploratorium is an OCLC member. Every collection-level resource
cataloged into our online library catalog will have a record submitted
to OCLC.
10. Describe
plans for submitting information about the project to a national
level registry of digital resources, such as the Association of
Research Libraries' Digital Initiatives Database (http://www.arl.org/did)
or OCLC's Cooperative Online Resource Catalog (http://www.oclc.com/corc/).
State reasons for selecting any alternative approaches:
We
will register our project to the Association of Research Libraries'
Digital Initiatives Database.
