Metadata should not contain duplicate schemas, so the ArgumentException will be thrown if metadata already contains schema with specified namespace prefix.
Creation of schemas with well-known prefixes is forbidden. Please use corresponding properties of XmpMetadata to access properties of a well-known schema.
Each schema consists of a schema name and namespace prefix. The name is a URI that serves to uniquely identify the schema. It is simply a unique string. A schema name looks like an URI (e.g. 'http://ns.adobe.com/xap/1.0/') but there might or might not be an actual Web page at the URI. The URI must obey XML namespace rules, and it should end in "/" or "#".
A schema namespace prefix is a short abbreviation for the full schema name. The prefix is used for properties in the schema.
