Supplementary Research Logs, Coding Manual, and Decision Rubric for "Toward a Universal Definition of the Digital Twin: A Property-Based Position"

Marian Tcaciuc, Olivier Bouriaud

This dataset contains the complete supplementary research logs and operational protocols supporting the paper: "Toward a Universal Definition of the Digital Twin: A Property-Based Position"Authors: Marian Tcaciuc, Olivier Bouriaud (Ștefan cel Mare University of Suceava) Dataset Contents Literature_Inclusion_Log.xlsx (173 unique entries) Contains the complete snowballing literature identification log following Wohlin (2014) guidelines. Includes unique citation keys, article metadata (authors, title, year, venue, primary domain), explicit inclusion/exclusion rationales, and domain classifications (Aerospace/Manufacturing, Smart Cities/Urban Governance, Healthcare/Medicine, Customer Analytics/Enterprise Systems). Proximity_Assessment_Log.xlsx (173 unique entries) Documents the structured proximity and novelty threat assessment for each candidate literature entry relative to the proposed property-based framework. Assesses structural, temporal, and functional overlap, categorizing prior works into baseline taxonomies, domain-specific implementations, and high-proximity conceptual frameworks. Supplementary_File_S3_Coding_Manual_and_Scoring_Rubric.pdf Provides the operational property-based coding manual, decision rubric, and inter-rater reliability protocol. Establishes explicit, evidence-anchored scoring rules for Fully Present (✓), Partially Present / Weak ((✓)), and Absent (×) states across all 10 Necessary Properties (N1–N10) and 5 Maturity Markers (M1–M5). Usage & Citation These data logs and operational protocols enable transparent verification, replication, and extension of the domain-agnostic Digital Twin qualification framework and decision-support pathway presented in the article.
