- Worth noticing
- The project measured limits across all 14 build variants, including record size, key length, record count, and file size.
Field notes
The page traces the engine’s lineage through UNESCO’s CDS/ISIS family and BIREME’s CISIS and WXIS, then frames XisCore as maintenance and packaging rather than a rewrite. It reports reproducible builds for Linux 32- and 64-bit and Windows 32-bit, and links to a limits document covering 14 variants. The single-command interface and conversion utilities are described as future goals, not current capabilities.
