GUIDELINES FOR USE

<part> is a container element used to provide detailed coding for physical parts of a resource. It may be used as a top level element to designate physical parts or under <relatedItem> for specifying the location of a part within a host/parent item.

Use <part> when the MODS record in question refers to either a physical or structural part of a resource, rather than an intellectual part. To indicate part names and numbers that are subordinate to the title as distinct intellectual items, use <title> with <partName> and/or <partNumber>.

A newspaper issue is generally indicated in MODS with <part>, rather than indicating the issue number as part of the title. The <part> element at the top level is also used to describe one reel of microfilm in a set, or in any other case in which the part being described is not an intellectual whole by itself. When in doubt and only part numbers or names are needed, use <titleInfo><title><partNumber> and/or <titleInfo><title><partName>.

When there is a separate intellectual entity with its own identity that is part of a larger work, use <relatedItem type="host"><part> to show the location of the part within that host item.

Specific DLF/Aquifer Guidelines

The DLF/Aquifer Implementation Guidelines for Shareable MODS Records recommend that the <part> element be used in cases where the part of a resource being represented is a physical or structural part of another resource. Examples include an issue of a journal or a single story from a collection.

Since there is not a controlled set of terms for the type attribute, if used the value should be expressed clearly and be generally understandable outside of the local context of the resource.

See the <part> entry in the DLF/Aquifer Summary of MODS Requirements and Recommendations Table for further information on requirements of this element, its attributes, and subelements.

Aggregator information: Aggregators may index <part> with other title information for search purposes; and may also include it in a full display.

The DLF/NSDL Best Practices for Shareable Metadata does not explicitly cover description of parts of resources. Some related issues are discussed on the "Granularity of Description" page.

MAPPINGS

MARC Mapping (Bibliographic)

There is no MARC 21 equivalent to <part> at the top level.

<part> used in <relatedItem type="host"> ≈ MARC 21 field 773, subfields g and q, but allows for additional parsing of data

<part><text> used in <relatedItem type="host"> = MARC 21 field 773 subfield g

See also MARC Mapping to MODS for the <relatedItem> element, <part> subelement.

Dublin Core Mapping

The MODS to Dublin Core Metadata Element Set Mapping does not include the <part> element in the mapping to Dublin Core.

The DLF/Aquifer Guidelines recommend adding information appearing at the highest level of the record to title information when mapping to simple Dublin Core.

MODS examples expressed in Dublin Core:

<dc:title>Washington observer volume 1</dc:title>
<dc:title>Non-subject-matter Outcomes of Schooling volume, volume 99, issue 5, page 131-146, 1999</dc:title>
