Referencing external sources

Schema: EAC-CPF 2.0

Context: Creating references to external sources from an EAC-CPF instance.

Description: To reference external sources for the contents of the EAC-CPF instance, encode the details of the external source in the <control> sections, using the <reference> element within <source>. <reference> is a required child element of <conventionDeclaration>, <localTypeDeclaration>, and <rightsDeclaration> for identifying any rules and conventions applied in the compilation of the description. It is also a required child element of <source>, used to identify any sources used in compiling the description. <source> may include multiple child <reference> elements.

<reference> is an optional child element of <abstract>, <chronItem>, <chronItemSet>, <event>, <eventDescription>, <item>, and <p> where it is used to reference any external resources that provide additional context to the contents of that element.

<reference> can include an @href attribute to point to a specific address for a remote resource.
