# Dublin Core

**A minimal 15-element metadata vocabulary for describing any resource — often reused as XMP schema.**

Dublin Core is a metadata standard created by librarians and information scientists in 1995. It defines 15 core metadata elements applicable to any resource — a document, image, website, dataset, or museum artifact. The vocabulary is intentionally minimal and language-agnostic, designed to be understood by both machines and humans.

## The 15 elements

Creator, Date, Description, Format, Identifier, Language, Publisher, Rights, Source, Subject, Title, Type, plus optional elements Contributor, Coverage, and Relation. These fields answer the basic questions: who made it, when, what is it, what language is it in, who published it, and where can I find more information. Dublin Core is so simple and universal that it appears in digital libraries, archives, content management systems, and — increasingly — in XMP metadata embedded in files.

## Why it shows up in XMP

Dublin Core is a common default in XMP toolchains. When you read metadata from a PDF or image in tools like Adobe Lightroom or the command-line ExifTool, you may see properties like `dc:creator`, `dc:title`, and `dc:description`. These are Dublin Core fields serialized in XMP. Every XMP-aware tool supports them.

## LLMind relationship

LLMind may populate Dublin Core fields when available — for instance, extracting `dc:creator` from camera EXIF author data or inferring `dc:description` from AI analysis. But the core AI semantics — extracted entities, document structure, transcription, lineage — live in the LRFS namespace, not in Dublin Core.
