MODS:physicalDescription

Comment: "physicalDescription" is a wrapper element that contains all subelements relating to physical description information of the resource described. Data is input only within each subelement.
Subelements: form

Definition: A designation of a particular physical presentation of a resource.

Application: "form" includes information that specifies the physical form or medium of material for a resource. Either a controlled list of values or free text may be used.

reformattingQuality

Definition: A term that indicates an overall assessment of the physical quality of an electronic resource in relation to its intended use.

Application: "reformattingQuality" is roughly equivalent to MARC 21 field 007/13 (ER). The following values may be used:

  • access - The electronic resource is intended to support current electronic access to the original item (i.e., reference use), but is not sufficient to serve as a preservation copy.
  • preservation - The electronic resource was created via reformatting to help preserve the original item. The capture and storage techniques ensure high-quality, long-term protection.
  • replacement - The electronic resource is of high enough quality to serve as a replacement if the original is lost, damaged, or destroyed. If serving more than one purpose, the element may be repeated.
internetMediaType

Definition: An identification of the electronic format type, or the data representation of the resource.

Application: "internetMediaType" specifies the electronic format type, such as text/html, ASCII, Postscript file, executable application or JPEG image. It is roughly equivalent to MARC 21 field 856 subfield $q, although subfield $q may also contain other designations of electronic format.. The "internetMediaType" value is generally taken from a controlled list, especially from the Internet Media types (MIME types) (see: www.iana.org/assignments/media-types/index.html for a complete list).

extent

Definition: A statement of the number and specific material of the units of the resource that express physical extent.

Application: "extent" may be used with electronic resources, e.g. digitized collection of slides, to show how many slides constitute the resource. It is roughly equivalent to MARC 21 fields 300 subfields $a, $b, $c, and $e and 306 subfield $a.

digitalOrigin

Definition: A designation of the source of a digital file important to its creation, use and management.

Application: "digitalOrigin" may indicate the source of a digital file important to its creation, use and management. It is roughly equivalent to MARC 007/11 (Antecedent/source) for electronic resources. The following values may be used:

  • born digital - A resource was created and is intended to remain in digital form. (No MARC equivalent, but includes value "c")
  • reformatted digital - A resource was created by digitization of the original item. (MARC 007/11 value "a")
  • digitized microfilm - A resource was created by digitizing a microform (MARC 007/11 value "b")
  • digitized other analog - A resource was created by digitizing a non-microform intermediate, which is in a format where the content is a reproduction of the original), e.g. an intermediate form such as photocopy, transparency, slide, etc. (MARC 007/11 value "d")
note

Definition: General textual information about the physical description of a resource.

Application: "note" is roughly equivalent to the types of notes that may be contained in MARC 21 fields 340, 351 or general 500 notes concerning physical condition, characteristics, etc. A link may be supplied in lieu of or in addition to the content. Each note should be entered in a separate "note" subelement. A list of note types used by MODS implementors has been compiled.
