Structured view of an XMP packet’s most useful fields.

All fields are best-effort scrapes — a malformed packet may produce partial data. Round-trip with a writer is not in scope: XMP is generally written by external tools (Adobe XMP SDK, exiftool, …) and read by the consumer.

Fields

dc_title: Option<String>

dc:title — usually wrapped in rdf:Alt for language alternatives; we surface the default-language sliver.

dc_creator: Option<String>

dc:creator — author(s); we collapse the rdf:Seq to the first entry (the common case is exactly one creator).

dc_description: Option<String>

dc:description — same shape as dc:title.

dc_subject: Vec<String>

dc:subject — rdf:Bag of keywords; we surface the full list in document order.

dc_rights: Option<String>

dc:rights — copyright statement; same shape as dc:title.

dc_format: Option<String>

dc:format — usually application/pdf for PDF documents.

xmp_create_date: Option<String>

xmp:CreateDate — ISO 8601 date-time at first creation.

xmp_modify_date: Option<String>

xmp:ModifyDate — ISO 8601 date-time at last modification.

xmp_metadata_date: Option<String>

xmp:MetadataDate — ISO 8601 date-time the XMP packet itself was last touched.

xmp_creator_tool: Option<String>

xmp:CreatorTool — application that authored the document (e.g. Adobe InDesign 16.0).

pdf_producer: Option<String>

pdf:Producer — application that wrote the PDF (often the same as xmp:CreatorTool but distinct in pipelines that separate authoring from rendering).

pdf_keywords: Option<String>

pdf:Keywords — same comma-separated list a PDF /Info dictionary’s /Keywords would carry.

pdf_version: Option<String>

pdf:PDFVersion — version of the PDF spec the file targets.

pdf_trapped: Option<String>

pdf:Trapped — True / False / Unknown per Adobe’s trapping convention.

pdfaid_part: Option<u8>

pdfaid:part — PDF/A part (1, 2, 3, 4) per ISO 19005-x.

pdfaid_conformance: Option<String>

pdfaid:conformance — conformance level (A, B, U, E, F) per ISO 19005-x §6.x.

Implementations

impl XmpPacket

pub fn parse(bytes: &[u8]) -> Self

Parse an XMP packet from the raw bytes returned by crate::reader::DocumentReader::xmp_metadata. Best-effort — missing fields surface as None, never errors.

pub fn is_pdf_a(&self) -> bool

True when the packet declares a PDF/A identification (per ISO 19005-x §6.x) — at minimum pdfaid:part is set.

pub fn pdf_a_conformance(&self) -> Option<String>

PDF/A conformance designator like 1B or 2A — concatenation of part + conformance — when both are declared.

Trait Implementations

impl Clone for XmpPacket

fn clone(&self) -> XmpPacket

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for XmpPacket

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for XmpPacket

fn default() -> XmpPacket

Returns the “default value” for a type.

impl Eq for XmpPacket

impl PartialEq for XmpPacket

fn eq(&self, other: &XmpPacket) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
