SDOCX Compatibility Corpus

This dataset contains paired Samsung Notes .sdocx documents and reference PDF exports for parser, renderer, and visual-regression testing. Each pair has a numeric ID and descriptive name recorded below.

The .sdocx file is the source fixture. The matching PDF is the expected visible result exported from Samsung Notes; it is a visual reference, not a byte-for-byte rendering requirement.

The 01-basic-formatting source archive stores six page records, while its reference PDF contains five visible pages. The 03-image-placement archive contains four page records and one embedded 451 × 300 RGB PNG, while its reference PDF contains three visible pages. Consumers should preserve stored structure separately from visible-page rendering semantics.

Intended use

• Check whether an SDOCX parser can load real Samsung Notes archives safely.
• Compare rendered output with the corresponding Samsung Notes PDF.
• Build focused compatibility tests for document structure, text, tables, links, code blocks, and styling.
• Track renderer changes with page-level visual diffs.

When comparing output, normalize page size and rasterization settings first. Font substitution, antialiasing, and PDF renderer differences can create harmless pixel-level changes.

Limitations

This is an early, synthetic compatibility corpus with two fixtures. It is not representative of every Samsung Notes version, device, font, pen type, embedded-media type, encrypted document, or malformed archive. A successful result on this dataset does not imply full SDOCX compatibility.

The SDOCX format is proprietary. This dataset documents observed behavior and does not provide or claim an official format specification.
