FLUD Format and Parser | Download | Installation | Operation | Results

Purpose

One of the research areas of the NIST Web Metrics Testbed is how to record the behavior of users as they attempt to perform given tasks during interaction with a Web-based application. The captured log data can be valuable for analyzing and improving the usability of such applications. This log data is quite complex and therefore a common file format is needed to allow various software components (such as recorders, parsers, analyzers, and visualizers) to exchange information. The goal then is to establish a Framework for Logging Usability Data - hence: "FLUD". NIST Special Publication 500-248 provides a full explanation of the design and rationale for FLUD.

Function

The parser accepts a logfile formatted as defined in the FLUD specification. It can generate three kinds of output: a parse file, a pretty-print HTML file, and a set of userpath files for VisVIP. A logfile represents the activity of one subject during a single test session.

Here is an example of a raw logfile and its pretty-printed representation.
