<phystech> Physical Characteristics and Technical Requirements

<phystech> is used to encode either physical or technical details which affect the materials. Physical characteristics may affect storage, preservation or use of materials. Technical details may include information about the hardware or software necessary to preserve or access the materials. This element is comparable to ISAD(G) data element 3.4.4 and MARC fields 340 and 538.

<phystech> is one of the elements which may be used within <archdesc>, <c>, <c01> … <c12>, and itself.


  • @altrender – not required. Use if the content of the element should be displayed or printed differently than the rendering established in a style sheet for other occurrences of the element.
  • @audience – not required. Use to set whether the element’s contents will be visible to external users or to internal ones. Possible values are: “internal” and “external.”
  • @encodinganalog – not required. May contain information to map this tag to a particular element in another schema.
  • @id – not required. Creates an ID for element. Can be used for linking.
