Scanning & Developing an Image Database
Updating older Multimedia Works
This will explain the T-shirt Image Database Project being done for
the IS 208 UCLA course Spring 2001. We will be taking Howard's 1995
T-Shirt Image Database, examining the updating done between the first version
of the data dictionary (1995) and the second version (2001), developing
Dublin Core mapping for the database, and adding new images and metadata
to the revised database. This assignment will give students practice
in scanning and metadata creation. It will also expose them to issues
in updating an older image database product (including data dictionary
revision, database update and migration, and user interface re-design).
And it will give them an idea of how more complex records can be mapped
to the Dublin Core. There will be several steps to this project:
Please Note: Under no circumstances should you wait
until just before the due dates to do this work. All these assignments
have sufficient lead-time to avoid congestion around scanners, boxes of
T-Shirts, or updating the database (which can only handle one user updating
at a time). The instructor will have no sympathy for students who
wait until the last week only to find that there's too much congestion
to make the assignment deadline.
due Jan 24: Students should familiarize themselves with the
Image Database (including performing at least a dozen complex queries).
They should examine the T-Shirt Data Dictionary,
version 2. In class they should be prepared to present ideas
of what fields need to be added to the data dictionary, which existing
fields need to be split or revised, etc. As a group we will discuss
Dublin Core mapping of the various fields.
due Jan 24: Choose your T-Shirt box and partner(s).
Check the list of how many T-Shirts per box,
and make sure that you're responsible for approximately 10 shirts.
due Feb 14x: Be prepared to discuss in class how the user
interface to the T-Shirt Image Database should be revised.
due Feb 14: By this date you will need to scan approximately
10 T-Shirts as master files.
The T-Shirts will be in the Computer Lab, and 2-3 students will be assigned
to divide up each box of T-Shirts. You must develop appropriate workflow
procedures between your small group to avoid duplicate scanning.
And you should develop some system for maintaining the integrity of organization
of the T-Shirt box (which should help you later on when you catalog these).
First check several T-Shirts against the T-Shirt
Image Database and against the records already in the Access database
to assure that each of the T-Shirts you're scanning and cataloging has
not already been entered into the database.
Follow the Lab's notes as to how to login so that your scanned files are
saved in a place with sufficient disk space.
Start scanning T-Shirts. (Use Photoshop, select the "File" menu and
choose "Import" then "Twain Acquire", and yhou will pull ups the Deskscan
software. Under "Type" select "millions of colors" and under "Path"
select "Screen".) Though this is not best practice, because of space
constraints you will scan each at 72 dpi, 24 bits (millions of colors),
crop, and save as an uncompressed TIFF file (your files should be approximately
1.9M each). Give each file a name that is unique (from among your
batch) but has some kind of meaning. DO NOT put spaces within file-names,
and stay away from special characters like asteriks, quotation marks, exclamation
Repeat for each T-Shirt making sure you save the file in the correct place.
due Feb 28: By this date you will need to have cataloged all
the T-Shirts you scanned, and enter the cataloging data into the database.
due March 7: By this date you will need to create screen-size
and thumbnail images for all the T-Shirt images you scanned.
