pdfXmp

XMP Metadata stream — ISO 32000-2 §14.3.2 / ISO 16684-1 (XMP).

Module pdfXmp | Source packages/front/office/pdf/src/metadata/xmp.js | Deps pdfErrors, pdfParser | Worker-safe yes

The Catalog may carry /Metadata, pointing to a stream /Type /Metadata /Subtype /XML. The content is an XMP (RDF/XML) packet. This module validates the stream's conformance (/Type, /Subtype, dict presence) and exposes the raw bytes; parsing the XML/RDF itself is left to the caller (no XML dependency embedded).

Resolve

const xmp = runtime.resolve('pdfXmp');
// Returns: { typeXmpStream }

API

Examples

Extracting the packet text

const xmp = runtime.resolve('pdfXmp').typeXmpStream(
    doc._raw.resolve(catalog.metadata)
);
const xml = new TextDecoder('utf-8').decode(xmp.bytes);
// → '<?xpacket begin=…?><x:xmpmeta …>…'

Common XMP fields

An XMP packet typically carries:

• dc:title, dc:creator, dc:description (Dublin Core).
• xmp:CreateDate, xmp:ModifyDate, xmp:CreatorTool.
• pdf:Producer, pdf:Keywords.
• pdfaid:part / pdfuaid:part (PDF/A and PDF/UA conformance).
