Supplementary Materials for the Manuscript Manuscript Title: Toward a Persian Website Post-Localization Testing Rubric: Identifying Essential Components Through a Sequential Mixed-Methods Design

This dataset contains the supplementary materials for the manuscript “Toward a Persian Website Post-Localization Testing Rubric: Identifying Essential Components Through a Sequential Mixed-Methods Design” and documents the full empirical basis of the study across three sequential phases. Phase 1 provides a structured document-analysis corpus of 143 sources, including academic publications, professional guidelines, web documentation, and gray literature, together with the search strategy, inclusion/exclusion criteria, coding protocol, and frequency counts that yielded 42 core evaluation elements organized into four dimensions: Linguistic Accuracy, Cultural Appropriateness, Functional Reliability, and Cosmetic Usability. Phase 2 includes the stakeholder questionnaire instrument, administration details, and descriptive statistics from 100 professionals (translators, localization specialists, and web developers), reporting response distributions, mean scores, standard deviations, and positive response rates for the 42 proposed rubric items plus two diagnostic items. Phase 3 contains the semi-structured interview protocol, participant profile, thematic coding framework, and thematic results derived from 15 expert interviews, showing how qualitative analysis refined and operationalized the rubric components. Together, these materials provide a transparent, reusable, and well-documented dataset for researchers interested in Persian website localization, post-localization testing, localization quality assessment, RTL usability, and mixed-methods rubric development.
