Re:       Joseph Urban Project Digital Images

 

 

Project end date:  June 30, 2004

 

 

Total images:  ca. 3200-3400

 

Images created in-house

§         1638 TIFs created to date of flat paper items; anticipate up to 1200-1400 more

§         scanned at 400 or 300 dpi depending on medium, mix of color and grayscale images

§         average file size 12 MB, ranging from 4 - 27 MB depending on medium

§         all images burned to CD

§         file name structure:

§         Urban IDs have the form  x.xx.xx.xx-xx, for example 3.33.47.02-01

§         file name is the Urban ID (minus the dots and hyphens) plus a sequential number assigned during scanning, for example 333470201-004

 

Luna scanning

§         scheduled to be sent to Luna in September with estimated return date in October

§         ca. 210 TIFs to be made from color 4x5 transparencies

§         scanned at 9k on the long side

§         average file size 193 MB

§         derivatives will be

§         SIDs at 15:1, file size 13 MB

§         JPEG thumbnail, 96 or 192 pixels on the long side

§         all images burned to CD

§         file name is the structure same

 

Primiano scanning

§         scheduled to be sent to Primiano in September with estimated return date in October

§         ca. 200 TIFs to be made from color 35 mm slides

§         scanned at 2400 on the long side

§         average file size ___ MB

§         derivatives will be

§         SIDs at 15:1, file size 13 MB

§         JPEG thumbnail, 96 or 192 pixels on the long side

§         all images burned to CD

§         file name structure is the same

 

Access to the images

 

According to the grant proposal

§         An extensive and detailed finding aid in both SGML/EAD and HTML formats has already been created and mounted online for the collection .  It will be updated and edited during the course of the project, and will be used as a basis for item control, digitization, conservation documentation, and online presentation of the collection.

§         The digital images will be linked to the online finding aid as well as being independently searchable.

§         As materials are selected and prepared for digitization, item-level identifiers will be incorporated into the finding aid to provide the basis for creating links to the digital reproductions.

§         This interim markup will be used to generate the following project tools:

§         An inventory listing of items to be digitized by vendor.

§         A supplementary data file to be used as input to Columbia's Name Resolver ("handle server") to provide permanent URLs for digitized items.  

§         A supplementary database to publish targeted web displays of those subsets of the collection with digitized content (e.g., all new photographs of set models, all original set photographs done during the New York period).

§         As items are digitized, the interim finding aid markup will be programmatically replaced with appropriate Entity References or URL links for presentation within a public version of the finding aid.

§         During the course of the project, the current SGML finding aid will be migrated to the new EAD XML standard, and newer XML toolsets such as XSLT will be used to create an easily navigable Web presentation.  Users will be able to locate digitized images from within the finding aid or from other Web-based presentations of the images.

 

 

Questions

 

The current spec for Luna is 9k on the long side -- do we want to change to 6k based on the conversations yesterday?

 

Does all scanning have to be completed before work on mounting the images begins?  If so, what is the deadline?

 

What is the deadline for last additions/changes to the Access version of the finding aid before it is converted to EAD and mounted?
