Based in grounded theory, open coding is the analytic process through which concepts (codes) are attached to observed data and phenomena during qualitative data analysis. It is one of the techniques described by Strauss (1987) and Strauss and Corbin (1990) for working with text. Open coding attempts to codify, name or classifying the observed phenomenon and is achieved by segmenting data into meaningful expressions and describing that data with a single word or short sequence of words. Relevant annotations and concepts are then attached to these expressions.
