The Colonial Archaeological Register of Java (CARJ): Site Observations from Dutch Oudheidkundig Verslag Reports, 1912-1929

A georeferenced database of 52 archaeological site observations extracted from Dutch colonial Oudheidkundig Verslag (OV) reports, 1912-1929. Each record includes site identification, location (WGS84), burial depth measurements, material descriptions, volcanic context, and condition assessments as documented by colonial surveyors of the Netherlands East Indies Archaeological Service. Key Statistics: - Entries recording a depth value: 34 of 52 (29 measured + 5 estimated); 32 are positive, 2 are surface finds recorded as 0 m - Positive burial depths (n=32): range 0.60-9.14 m, mean 2.88 m, median 1.75 m (measured subset only, n=27: median 2.00 m) - Entries with coordinates: 43 (83%) - Entries with volcanic system: 44 (85%) This dataset was extracted with AI assistance (large language model); each record cites its source volume and page (ov_page) for verification. A data paper describing this dataset is in preparation.
