What is Silver XMP

Silver XMP is the official metadata namespace used by Silver Lab to describe film scans with roll-centric provenance, capture context, and lab processing notes. It travels with each frame so archives remain portable across systems, DAMs, and file formats.

Purpose

Preserve lab and capture facts alongside every TIFF/JPEG so the record of how the roll was shot, processed, and scanned is never lost.

Scope

Fields cover roll identity, capture format, stock, processing, scan parameters, and portability guidance for standard XMP mappings.

Namespace

Use the Silver namespace prefix and URI when embedding fields inside XMP.

prefix: silver uri: https://silverlab.app/xmp/1.0/

Quickstart

Add the namespace declaration and core fields inside your XMP packet:

<x:xmpmeta xmlns:x="adobe:ns:meta/">
  <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:silver="https://silverlab.app/xmp/1.0/">
    <rdf:Description rdf:about=""
      silver:SchemaVersion="1.0"
      silver:SchemaUrl="https://silverlab.app/xmp/1.0/"
      silver:RollId="SL-2024-118"
      silver:FrameNumber="118-06"
      silver:FilmStock="Portra 400"
      silver:ProcessType="c41"
      silver:ScannerModel="Frontier SP-3000"
      silver:ScanDpi="4000"/>

Compatibility

Silver fields live inside standard XMP. Key fields are mirrored to well-known properties so downstream DAMs and catalogers can read them without Silver awareness:

  • Keywords and tokens flow into dc:subject.
  • Summaries mirror to dc:description and dc:source.
  • Rights language can mirror into dc:rights and Iptc4xmpCore:RightsUsageTerms.

If a consumer does not understand Silver fields, mirrored standard fields preserve essential context.
