To keep the text-based search field updates low, you could organize
based on month. All submissions are organized based on date into text
files organized by month and year. The search fields and download
locations could be incorporated into these same text files and easily
updated. You would want to put some thought into your search fields,
because the only time an update would take more time is if you were to
revise your organizational structure for searches. You would have to
update every single text file for each month from the very beginning if
your were to do this. Being text files it might not be so bad. I guess
it depends on the size of the files.
The more we can work with the materials already to hand, probably the
easier. All of the graphics are already available in small bite-size
png chunks. I'm not sure how everything is currently set up, but how
about assigning a descriptive permanent name to each png graphic which
then becomes a permanent key. Perhaps it could be done using a numeric
sequence which is the date and time of submission and/or acceptance into
the database. This would practically guarantee a completely unique key
for each graphic. That permanent sequence then can be attached to all
kinds of information, including search data (descriptive terms, size,
colors, author, date, whatever). That sequence could be attached in a
local utility to a download function for png for quick local searches,
but it could also be used to define the svg download. Your update
function in the local utility could be used to update a text based file
or files which would update the search fields any time you wanted.
Quick downloads with easy updates to search functionality. Your png
graphics for local search would also be quick downloads in the small
chunks. The biggest update of course would be the first update where
the utility and the bulk of the png graphics would be downloaded. After
that, it would be just very small chunks of updates for search fields
and added png graphics. When a graphic or graphics is chosen for svg
download, the choices are loaded into a component of the utility which
knows to look for the svg component attached to the permanent key.
This allows complete flexibility with updating the search fields, easy
identification of graphics based on a permanent key, quick updates
locally after initial installation, offloading of search function and
storage to local system, increase of apparent speed in searches due to
local storage, redundancy should the www or the server be slowed down,
and enables the user to use the png graphics should the svg not be
I'm sure I've missed things, and I'm not a programmer (yet), but would
it be possible to set this up?
