Orchestration, Interoperability, and Architecture in LLM-Based Multi-Agent Systems: Replication Package for a Systematic Mapping Study

This record contains the research artifact accompanying the paper “Orchestration, Interoperability, and Architecture in LLM-Based Multi-Agent Systems: A Systematic Mapping Study”, accepted at the Brazilian Symposium on Software Engineering (SBES 2026), held as part of CBSoft 2026. The artifact documents a Systematic Mapping Study on the integration of Multi-Agent Systems (MAS) and Large Language Models (LLMs), with emphasis on agent orchestration, inter-agent communication, interoperability, system architecture, practical applications, technical challenges, limitations, and research gaps. The package includes the methodological and analytical workbook, records retrieved from IEEE Xplore, ACM Digital Library, and Web of Science, consolidation and deduplication controls, study-selection decisions, research-question classifications, analytical categories, extracted evidence, synthesis tables, data dictionaries, audit instructions, version history, and integrity checks. The dataset comprises 436 retrieved records, 325 unique records after deduplication, 166 studies included in the final corpus, 561 study–research question–category coding records, and 31 analytical categories. The artifact was organized to support availability, auditability, traceability, inspection, reuse, and reproduction of the main descriptive results reported in the paper. The methodological workbook and supporting documentation are primarily written in Portuguese, while the repository documentation includes English descriptions for international accessibility.
