Sean Kandel, Andreas Paepcke, Martin Theobald, Héctor García-Molina · Max Planck Digital Library · 2007
This document defines the data model as well as the syntax and semantics of the formula language employed by PhotoSpread. It is inspired by Excel with specialized and enriched functionality for managing and tagging large photo collections in a spreadsheet. PhotoSpread allows for capturing, storing, arranging, manipulating, and querying arbitrary tagged photo objects with an intuitive and easy-to-learn, yet expressive formula language.
