HERITRACE user testing results: usability evaluation and qualitative analysis

This dataset contains complete user testing data and results for HERITRACE, a semantic content management system for cultural heritage institutions. The study involved 14 participants divided into two groups: end users (7 participants) and configurators (7 participants).

The dataset combines quantitative metrics (SUS scores, task duration, error rates, success rates) with qualitative analysis following grounded theory methodology (open, axial, and selective coding). All data is provided in accessible formats (JSON for structured data, Markdown for textual content, PNG for visualizations), enabling reproducibility and secondary analysis.
