In addition to adding Keywords to organize files Media Purveyor will let you define collections of user defined fields. Each set of user defined fields is called an Entry Screen and can be thought of like a worksheet, a form, or, in database circles, a table. Field data can be entered for individual files or values can be batch applied to a group. Field types include: Short and Long Text, Decimal, Date, List, Check List, Integer, and Boolean.
Search field data either using a simple graphical interface or write your own SQL-like search expressions (advanced users).
All field data is portable since it is stored inside the media files and anyone can search files using field data added by another person in the sharing community (to edit or modify field information you need to share the Entry Screen Definition file).
