The designation of physical parts of a resource in a detailed form.
"part" is 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. It may be used under relatedItem for generating citations about the location of a part within a host/parent item. When used with relatedItem type="host", "part" is roughly equivalent to MARC 21 field 773, subfields $g (Relationship information) and $q (Enumeration and first page), but allows for additional parsing of data. There is no MARC 21 equivalent to "part" at the "mods" level.
To indicate part names and numbers that are subordinate to the title as distinct intellectual items, use "title" with "partName" and/or "partNumber". 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.
Application: "detail" contains numbering and type of designation of the part in relation to the host/parent item in which a host item resides.
Application: "extent" contains the measured units making up the part, such as pages, minutes, etc.
Application: "date" contains date information relevant to the part described.text
Application: "text" contains unparsed information in textual form about the part. When used in relatedItem type="host", it is equivalent to MARC 21 field 773 subfield $g.
