Rupe Magna — Reflectance Transformation Imaging (RTI) Datasets for Digital Documentation (RAW, PTM, and Processed Images)

This record contains Reflectance Transformation Imaging (RTI) acquisition and processing datasets from the Rupe Magna petroglyph survey (Grosio, Valtellina, Lombardy, Italy). These datasets constitute the reference data underlying the MSc thesis "Digital Documentation of the Rupe Magna: A FAIR Data Framework and a Portable RTI Dome" This record provides 24 RTI capture datasets, distributed across 11 rock-art figures (F01–F11) — a subset of the full 40-session Rupe Magna campaign recorded in September 2025 with a Fujifilm X-S20, Fujifilm XF 16–55 mm f/2.8 R LM WR zoom lens and a custom RTI dome (48 LEDs, 6 elevation rings). Each capture is provided as a self-contained ZIP archive named FXX_RTI-YY.zip, and every archive expands to the same canonical directory tree. Every dataset can be downloaded individually — any single FXX_RTI-YY.zip to obtain one complete RTI capture on its own. 02-datasets/Rupe Magna/<Figure>/<Session>/ ├── raw/ RAW capture files (where available) ├── ptm/ RelightLab PTM model + info.json └── jpg-export-linear-LC/ processed images (Linear Rec.709) or jpg/ in-camera JPEGs (captures without RAW) Pipeline compatibility. The data is organised to be processed end-to-end by two companion pipelines developed for the Rupe Magna project: RTI-FLOW (RAW → JPEG using darktable-cli → RTI model generation with relight-cli → PTM quality check) semRTI (RTI survey data → FAIR RDF/Turtle knowledge graph, aligned to CHS-ODP, ArCo, CIDOC CRM (crm/crmdig/crmsci), DCAT 3 and PROV-O)
