3EUNSTRUCTURED DATA PREPARATION
This chart illustrates
the hours worked to make unstructured data available. During Year 1
only three universities, (American, Maryland and Michigan) processed
unstructured data. All three of them spend the same amount of hours
in Year 1 as in Year 2. Maryland spent the most time at 211 hours both
years. In Year 2, Columbia and Virginia made unstructured data available;
they spent 21 and 4 hours respectively. Cornell and Illinois did not
make unstructured data available either year.
data was copied to the Web server, then it was hyperlinked from the
structured data screen. All unstructured data was displayed as provided
by the museums; the only changes made were the addition of background
texture, and the addition of HTML tags to indicate title as opposed
to body text.
data was made available as linked text-only (ASCII) files; no additional
processing was done. References to the unstructured data were provided
in the structured records, and the exporting program linked the files.
A programmer wrote code in shell script.
data was made available through a feature in SearchSlide. After
the unstructured files were placed in their subdirectory, the SearchSlide
program determined the path using the file names provided by the museums
and the filename contained in the record field. The data was uploaded
from the CD-ROMs without any processing. There were no problems encountered
during this process. Programs were written in Visual Basic
script was used to generate all the detailed information displays in
advance, then links were made by the script to associated text files.
In order to deal with the inconsistencies across the museum data, they
wrote separate Perl scripts for each museum. The data was made available
through a hyperlink from the full record. They added HTML headers and
footers and often converted the body of the text to HTML in order to
enhance the formatting.
data was made available during Year 2. A simple link was made by Perl
script, which wrote the full record HTML page to check for the existence
of an unstructured text and make a link to the path/filename if there
