Image ID numbers
Agave64 utilizes image ID number templates consisting of an alpha or numeric prefix coupled with an auto increment sequence number and optionally, a two digit extension to indicate dupes. The prefix serves as a location, subject or date code and enables like subjects to be sorted as a group in the Fotofile database for easy browsing and  fast searches.

Location based prefix:
A location based prefix is popular with landscape photographers. If you need to create a prefix for Yosemite National Park, CA and you have selected an ID number template utilizing a 4 character prefix code, you might use CAYO (CAlifornia+ YOsemite). For landscapes, a lot of photographers like to place the container area first in the prefix which is this case would be California or CA.   A resulting IDnumber might look like: CAYO-0034.

Date based prefix:
Many digital shooters prefer to organize their images by date. Using the Agave template generator, you can create a date prefix that would look like:
100329-001 (2 character year + month + date + sequence number= March 29, 2001 - image #1) or 20100329-001 (4 character year + month + date). 

Date & Location/Subject based prefix:
To create a prefix template that's searchable on location/subject as well as date, you could use 100329GC-001 (2 character year + month + date + alpha location code = March 29, 2010 Grand Canyon.)  Alternatively, you could group on location first, by using GC100329-001. 

Author's System:
AB100301  (2 character Location code + 2 character year + 2 character month + image #1) This economical system allows a maximum of 99 images for a single location per month. But to be honest, over the course of 20+ years, I have yet to capture more than 99  *keepers* in a given month, for a single location.


Prefix Management
For easy reference, each code is linked to a descriptive phrase and stored in a look-up database. The example here is showing alpha prefixes. Date type prefixes will display in the same manner.
