What ISO 16684 (XMP) requires
ISO 16684 establishes the framework for embedding extensible metadata within digital assets using the Extensible Metadata Platform (XMP) specification. Compliance mandates a strict structural and semantic adherence to ensure interoperability and data integrity across systems. The standard requires that all XMP metadata be enclosed within a valid packet wrapper, serialized specifically as RDF/XML, and universally encoded in UTF-8 for character set compatibility. A foundational rule dictates that the main rdf:Description element possesses an empty rdf:about attribute, designating the metadata as pertaining to the enclosing document. Furthermore, all namespace declarations must be valid to prevent ambiguity. For data representation, property values must strictly conform to their designated datatypes, and any embedded binary information is required to be encoded as Base64. When representing ordered lists, the standard obligates the use of rdf:Seq containers. Core content requirements stipulate the presence of a minimum of three critical properties to achieve baseline compliance: dc:creator for authorship, dc:rights for copyright information, and xmpMM:DocumentID for unique asset identification. This node rigorously validates these technical prerequisites to certify that digital files meet the comprehensive requirements for metadata interchange as defined by the governing international standard.
