Sobre os arquivos YAMLComparativo de vantagens
EPUB Vantagens
- Open standard — no vendor lock-in, no DRM required.
- Reflowable text — adapts to any screen size, font size, or orientation.
- Rich typography via CSS, embedded fonts, and SVG.
- Accessibility-first: native support for screen readers, adjustable text, and alt-text.
- Universal across every non-Kindle ebook reader and library app.
YAML Vantagens
- Human-readable — the most legible config format in common use.
- Comments supported (unlike JSON).
- Multi-line strings, references, and anchors.
- Adopted by every major DevOps tool.
- Superset of JSON — valid JSON is valid YAML.
Limitações
EPUB Limitações
- Kindle does not support EPUB natively (Amazon wants you to convert to AZW3).
- Fixed-layout EPUBs (for children's books, comics) are awkward to author.
- Rendering quality varies between apps — some CSS works everywhere, some does not.
- Adobe DRM (ADEPT) or Apple FairPlay are optional layers that complicate portability.
YAML Limitações
- Indentation-sensitive — a misplaced space can silently change meaning.
- Implicit type coercion causes subtle bugs (NO → false, 22:00 → seconds, 1.0 → float).
- Multiple inconsistent implementations across languages.
- Parser CVEs appear regularly (YAML bombs, deserialization RCE).
- Slower to parse than JSON.
