Format-Specific Extraction Workflows

Office XML (DOCX/PPTX/ODT)

ZIP archive → Security validation → XML parsing → Text + tables + metadata

ZipBombValidator::new(limits).validate(&mut archive)?
Extract XML files from archive (word/document.xml, ppt/slides/*.xml, content.xml)
Parse with quick-xml::Reader (streaming) + DepthValidator + StringGrowthValidator
Extract metadata via crate::extraction::office_metadata::extract_metadata()
See: extractors/docx.rs, extractors/pptx.rs, extractors/odt.rs

PDF

Bytes → pdfium-render → Per-page text + OCR fallback → Tables → Metadata

pdfium.create_document_from_bytes(content, None)?
Check if needs OCR: config.force_ocr || !has_searchable_text()
Extract text per page, tables if config.pages enabled
Feature-gated: #[cfg(feature = "pdf")]
See: extractors/pdf/mod.rs

Archives (ZIP/TAR/7z/GZIP)

Validate → Extract metadata → Extract plaintext files only

ZipBombValidator BEFORE any extraction
Extract metadata (file list, sizes)
Extract text content from plaintext files
Use build_archive_result() helper
See: extractors/archive.rs, extraction/archive/*.rs

Structured Text (JSON/YAML/TOML/XML)

Detect format from MIME → Parse → Pretty-print → Metadata

Single StructuredExtractor handles multiple MIME types. Parse with format-specific library, pretty-print to text. See: extractors/structured.rs

Email (EML/MSG)

Parse headers → Extract body (text/html) → Process attachments

See: extraction/email.rs, extractors/email.rs

Common Helpers

Helper	Location	Purpose
`office_metadata::extract_metadata()`	`extraction/office.rs`	Office XML metadata
`cells_to_markdown()`	`extraction/mod.rs`	Convert cell grid to GFM table
`build_archive_result()`	`extraction/archive/mod.rs`	Standard archive result

Adding a New Format

Add MIME type to EXT_TO_MIME in core/mime.rs
Create extractor implementing DocumentExtractor trait
Set supported_mime_types() and priority() (default: 50)
Register in extractors/mod.rs → register_default_extractors()
Feature-gate if optional: #[cfg(feature = "my-format")]
Apply security validators for user content
Add tests with fixture files
