http://www.hathitrust.org/documents/hathitrust-mets-profile2.0.xml This profile specifies how METS documents stored in the Hathi Trust Digital Library should be encoded. This profile should be used for all HathiTrust METS documents related to digitized versions of previously printed monographs and journals. The profile applies to documents in all namespaces. 2012-11-12T17:00:00 Chris Powell

(734) 763-9185 sooty@umich.edu There are no related profiles. This profile describes the encoding and structure of a METS document created at the point of ingest into HathiTrust. PREMIS, Preservation Metadata http://www.loc.gov/standards/premis/v2/premis.xsd mets/amdSec/digiprovMD/mdWrap/xmlData HathiTrust uses PREMIS to encode both preservation metadata at the time of ingest and throughout any preservation events that occur while the document is in the repository. Date information recorded within a conforming METS document aside from elements within the MARC XML Schema must conform to ISO 8601 format. ISO 639-2 International Standard Organization http://www.iso.ch/ All information recorded within the portion of a conforming METS document defined using the MARC XML Schema must employ ISO 639-2 language codes within the controlfield[@tag=008] element. ISO language codes. MARC Country Codes Library of Congress Network Development & MARC Standards Office http://www.loc.gov/marc All information recorded within the portion of a conforming METS document defined using the MARC XML Schema must employ MARC Country codes within the datafield[@tag=043] element. MARC Country codes. The ID attribute in the metsHdr element must be present. It will contain the namespace and identifier for the item, separated by a period (e.g., uc1.b3387194). This value must match the OBJID attribute on the mets root element. The CREATEDATE attribute in the metsHdr element must be present. The RECORDSTATUS attribute in the metsHdr element must be present. The value must be "NEW" for the first version of any HathiTrust METS document and "REV" for any subsequent versions. A conforming metsHdr must contain an agent element identifying the creator of the METS document (as opposed to the creator of the electronic files it describes). A conforming METS document must contain at least one dmdSec with an ID of "DMD1" containing a mdRef to an item ID stored in the HathiTrust metadta management system and an XPTR with the value of the metsHdr ID. This must be the first dmdSec in a conforming METS document. A conforming METS document will not contain another dmdSec. A conforming METS document may contain a techMD element with an MDWrap with a LABEL attribute of "reading order" containing relevant metadata regarding page order. A conforming METS document must contain a digiprovMD element with an MDWrap containing all relevant PREMIS objects, events, and associated metadata as specified in the PREMIS Data Dictionary version 2.0 (http://www.loc.gov/standards/premis/). A conforming METS document will contain up to six file groups as follows: The first file group, for the zip archive, must have an ID of "FG1" and a USE of "zip archive". It must contain one file element. The file element will contain the following attributes: ID, MIMETYPE, SEQ, CREATED, SIZE, CHECKSUM, CHECKSUMTYPE. The file element will contain an FLocat subelement with an xlink:href to the file described. Additional file groups will have IDs FG2, FG3, etc. If present, they can include: There must be a file group for page images (bitonal and continuous tone), which must have a USE of "image". It will contain a file element for each image. The file elements will contain the following attributes: ID, MIMETYPE, SEQ, CREATED, SIZE, CHECKSUM, CHECKSUMTYPE. Each file element will contain an FLocat subelement with an xlink:href to the file described. A conforming METS document may contain a file group for the source METS file for the deposited document. If included, it must have a USE of "source METS". It must contain one file element. The file element will contain the following attributes: ID, MIMETYPE, SEQ, CREATED, SIZE, CHECKSUM, CHECKSUMTYPE. The file element will contain an FLocat subelement with an xlink:href to the file described. A conforming METS document may contain a file group for OCR files including word-coordinate encoding. If included, it must have a USE of "coordOCR". It will contain a file element for each page of OCR. The file elements will contain the following attributes: ID, MIMETYPE, SEQ, CREATED, SIZE, CHECKSUM, CHECKSUMTYPE. Each file element will contain an FLocat subelement with an xlink:href to the file described. A conforming METS document may contain a file group for OCR text files. If included, it must have a USE of "ocr". It will contain a file element for each page of OCR. The file elements will contain the following attributes: ID, MIMETYPE, SEQ, CREATED, SIZE, CHECKSUM, CHECKSUMTYPE. Each file element will contain an FLocat subelement with an xlink:href to the file described. A conforming METS document may contain a file group for a full PDF of the volume. If included, it must have a USE of "pdf". It must contain one file element. The file element will contain the following attributes: ID, MIMETYPE, SEQ, CREATED, SIZE, CHECKSUM, CHECKSUMTYPE. Each file element will contain an FLocat subelement with an xlink:href to the file described. A conforming METS document must contain only one structural map with a type value of "physical". There must be a div element for the volume within the structural map which will contain a div for each page. Each div must have a ORDER attribute, a TYPE attribute of "page" and contain an fptr to the matching page image file and to all matching OCR or structured files, if applicable. In addition, page divs may contain LABEL and ORDERLABEL attributes, as appropriate. A conforming METS document must not contain a structLink element. A conforming METS document must not contain a behaviorSec element. All bitonal images referenced by a conforming METS document must be in TIFF format and must be well-formed and valid. The MIME type must be image/tiff. The compression scheme must be CCITT Group 4. Bits per sample must be “1”. Bitonal images may be accompanied by an XMP packet.
