The metadata reference element <mdRef> element is a generic element used throughout the METS schema to provide a pointer to metadata which resides outside the METS document. NB: <mdRef> is an empty element. The location of the metadata must be recorded in the xlink:href attribute, supplemented by the XPTR attribute as needed.
CHECKSUMTYPE (enumerated string/O): Specifies the checksum algorithm used to produce the value contained in the CHECKSUM attribute. CHECKSUMTYPE must contain one of the following values:Adler-32CRC32HAVALMD5MNPSHA-1SHA-256SHA-384SHA-512TIGERWHIRLPOOL
ID (ID/O): This attribute uniquely identifies the element within the METS document, and would allow the element to be referenced unambiguously from another element or document via an IDREF or an XPTR. For more information on using ID attributes for internal and external linking see Chapter 4 of the METS Primer.
MDTYPE (string/R): Is used to indicate the type of the associated metadata. It must have one of the following values:MARC: any form of MARC recordMODS: metadata in the Library of Congress MODS formatEAD: Encoded Archival Description finding aidDC: Dublin CoreNISOIMG: NISO Technical Metadata for Digital Still ImagesLC-AV: technical metadata specified in the Library of Congress A/V prototyping projectVRA: Visual Resources Association CoreTEIHDR: Text Encoding Initiative HeaderDDI: Data Documentation InitiativeFGDC: Federal Geographic Data Committee metadataLOM: Learning Object ModelPREMIS: PREservation Metadata: Implementation StrategiesPREMIS:OBJECT: PREMIS Object entiryPREMIS:AGENT: PREMIS Agent entityPREMIS:RIGHTS: PREMIS Rights entityPREMIS:EVENT: PREMIS Event entityTEXTMD: textMD Technical metadata for textMETSRIGHTS: Rights Declaration SchemaISO 19115:2003 NAP: North American Profile of ISO 19115:2003 descriptive metadataEAC-CPF: Encoded Archival Context - Corporate Bodies, Persons, and FamiliesLIDO: Lightweight Information Describing ObjectsOTHER: metadata in a format not specified above
MDTYPEVERSION(string/O): Provides a means for recording the version of the type of metadata (as recorded in the MDTYPE or OTHERMDTYPE attribute) that is being used. This may represent the version of the underlying data dictionary or metadata model rather than a schema version.
MIMETYPE (string/O): The IANA MIME media type for the associated file or wrapped content. Some values for this attribute can be found on the IANA website.
OTHERLOCTYPE (string/O): Specifies the locator type when the value OTHER is used in the LOCTYPE attribute. Although optional, it is strongly recommended when OTHER is used.
XPTR (string/O): Locates the point within a file to which the <mdRef> element refers, if applicable.

A metadata wrapper element <mdWrap> provides a wrapper around metadata embedded within a METS document. The element is repeatable. Such metadata can be in one of two forms: 1) XML-encoded metadata, with the XML-encoding identifying itself as belonging to a namespace other than the METS document namespace. 2) Any arbitrary binary or textual form, PROVIDED that the metadata is Base64 encoded and wrapped in a <binData> element within the internal descriptive metadata element.

ADMID (IDREFS/O): Contains the ID attribute values of the <digiprovMD>, <techMD>, <sourceMD> and/or <rightsMD> elements within the <amdSec> of the METS document that contain administrative metadata pertaining to the current mdSecType element. Typically used in this context to reference preservation metadata (digiprovMD) which applies to the current metadata. For more information on using METS IDREFS and IDREF type attributes for internal linking, see Chapter 4 of the METS Primer.
GROUPID (string/O): This identifier is used to indicate that different metadata sections may be considered as part of a group. Two metadata sections with the same GROUPID value are to be considered part of the same group. For example this facility might be used to group changed versions of the same metadata if previous versions are maintained in a file for tracking purposes.
ID (ID/R): This attribute uniquely identifies the element within the METS document, and would allow the element to be referenced unambiguously from another element or document via an IDREF or an XPTR. The ID attribute on the <dmdSec>, <techMD>, <sourceMD>, <rightsMD> and <digiprovMD> elements (which are all of mdSecType) is required, and its value should be referenced from one or more DMDID attributes (when the ID identifies a <dmdSec> element) or ADMID attributes (when the ID identifies a <techMD>, <sourceMD>, <rightsMD> or <digiprovMD> element) that are associated with other elements in the METS document. The following elements support references to a <dmdSec> via a DMDID attribute: <file>, <stream>, <div>. The following elements support references to <techMD>, <sourceMD>, <rightsMD> and <digiprovMD> elements via an ADMID attribute: <metsHdr>, <dmdSec>, <techMD>, <sourceMD>, <rightsMD>, <digiprovMD>, <fileGrp>, <file>, <stream>, <div>, <area>, <behavior>. For more information on using ID attributes for internal and external linking see Chapter 4 of the METS Primer.
