Definition

Material Type

A term that specifies the characteristics and general type of content of the resource.¹

This term gives basic specifications on the general category of the original resource. The terms used in this field are taken from a controlled list which includes:

• Book Chapter for a single chapter from a book
• Conference Papers for a paper given at a conference
• Conference Proceedings for proceedings from a conference
• Course Material for any items which were created for instruction
• Journal Article for an article written for or submitted to a journal
• Other for any other material
• Technical Reports for technical reports

You must select one of the types from the list above.

Larger Body of Work

Enter the title of the book or journal in which your material is published. If you are submitting material related to a conference or class, you may identify it here. If your material is not included in a larger body of work, please leave this field blank.

Form Element

In the online templates, this element initially appears as below:

This element provides access to both the material type information and the basic identification of any larger body of work.

Best Practices

Select the term which most applies to the material which was digitized. Additional refinement can be placed in the genre or physical description fields.

Enter the title of the book or journal in which your material is published. If you are submitting material related to a conference or class, you may identify it here. If your material is not included in a larger body of work, please leave this field blank.

SobekCM / MODS Encoding

This data is encoded in both the MODS metadata and in the bibliographic descriptor section of the custom SobekCM metadata. This is included in the SobekCM schema to provide for the controlled list from above. It is additionally encoded within the MODS section to allow for greater portability of the resulting METS files. The METS schema provides for its own controlled list; mapping between these lists appears below:

SobekCM Term	MODS Term(s)	Implementation Notes
Aerial	still image
Artifact	three dimensional object
Audio	sound recording
Book	text
Mixed Material	mixed material
Map	cartographic
Newspaper	text
Photograph	still image
Serial	text
Video	moving image
(unused)	notated music
(unused)	software, multimedia
(unused)	sound recording-musical	maps to Audio
(unused)	sound recording-nonmusical	maps to Audio

Examples of the related pieces of metadata appear below:

<mods:typeOfResource>text</mods:typeOfResource>
<SobekCM:Type>Book</SobekCM:Type>

<mods:typeOfResource>text</mods:typeOfResource>
<SobekCM:Type>Newspaper</SobekCM:Type>

<mods:typeOfResource>still image</mods:typeOfResource>
<SobekCM:Type>Aerial</SobekCM:Type>

Metadata Mapping

MARC to MODS Mapping

The type is determined by looking at the Leader, positions 006 and 007. If the material is series, then the 008 field's 021 position is used. This determines the SobekCM Type, as well as the MARC type, which impacts other mappings from the leader. Complete mapping is included below.

Leader/006	SobekCM Type	MARC Type
a, c, d, or t	Book	BKS
e or f	Map	MAP
i or j	Audio	REC
k	Photograph	VIS
g	Video	VIS
r	Artifact	VIS
m	Mixed Material	COM
p	Mixed Material	MIX
o	Mixed Material	VIS

Once the primary type is determined, the following mapping is checked:

• If Leader/007 equals 'c', the collection attribute is set to true
• If Leader/007 equals 's', the type is set to Serial and marc type is set to CNR
• If Leader/007 equals 's' and 008/021 equals 'n', the type is set to Newspaper

MODS to MARC Mapping

Mapping from the MODS back to MARC is generally the reverse of the procedure listed above.
