PdfXmpMetadata

data class PdfXmpMetadata(val title: String? = null, val authors: List<String> = emptyList(), val description: String? = null, val keywords: String? = null, val subjects: List<String> = emptyList(), val producer: String? = null, val creatorTool: String? = null, val createDate: String? = null, val modifyDate: String? = null, val metadataDate: String? = null, val pdfVersion: String? = null, val xml: String)

Parsed view of an XMP (Extensible Metadata Platform) packet stored in the catalog's /Metadata stream. The XMP spec is ISO 16684-1; in PDF it's referenced from ISO 32000-1 §14.3.2 (PDF 2.0 §14.3) as the preferred way to carry document metadata. PDF 2.0 deprecates the trailer /Info dict but in practice readers consult both.

We extract the most common Dublin Core / Adobe PDF / XMP-basic properties. Anything else can be pulled from the xml string by the caller using their preferred XML tool — we don't ship a full XML parser.

Date fields are exposed as raw ISO 8601 strings (XMP uses 8601 rather than PDF's D:YYYYMMDDHHmmSS... form).
