The following requirements are imposed by the Complex Ingest workflow that go beyond the well-formatted XML and the validation by the provided XSDs.

Every file in the archive must be referenced by the METS. If files are not referenced or if a referenced file is missing, the entire archive is rejected.
The MD5 checksums provided in the XML are compared against the calculated MD5 checksums. The entire archive is rejected if one check fails.
The file paths used in the METS are paths relative to the root the accompanying archive.

METS Validation

View file

name	mets.xsd

...

View file

name	xlink.xsd

...

Do not use a default namespace for the METS tags but use the explicit namespace prefix mets, e.g. mets:agent.
Use exactly one tag mets:fileGrp under which all tags mets:file are placed.
The value of the attribute ID is of the type xsd:id which means it must be unique accross the XML document and be a valid CNAME. This means that it must start with a letter or underscore, and can only contain letters, digits, underscores, hyphens, and periods. More info here.
The tag <mets:structMap> must be provided with the self-closed tag <mets:div /> in order have a valid METS XML.

TIP

Tip

title

TIP

It is important to validate the METS which you generate with the provided XSDs before uploading them to the platform. This will prevent the need for fixing common errors. You can validate the XML using online tools, for example: http://www.xmlvalidation.com/. It is important that you place the XSD xlink.xsd in the same folder as mets.xsd.

Common mistakes

Tip

The value of the attribute ID must be a valid XML tag name which has the following rules:

Must start with a letter or underscore
Cannot start with the letters xml (or XML, or Xml, etc)
Can contain letters, digits, hyphens, underscores, and periods
Cannot contain spaces

Tip
Because the value of the attribute attribute `xlink:href` must must be a valid URI, you will have to URI encode its value if the path to the file contains illegal URI symbols such as as `?` `%` etc etc.

Warning
Because the value of the attribute `xlink:href` must be a valid URI, you will have to URI encode its value if the path to the file contains illegal URI symbols such as `?` `%` etc.

ID: The value if of the type xsd:id which means it must be unique accross the XML document and it must start with a letter or underscore, and can only contain letters, digits, underscores, hyphens, and periods. More info here.
CHECKSUMTYPE: Fixed value "MD5"
CHECKSUM: The MD5 checksum of the referenced file
USE: PRESERVATION, FIXITY, VIRTUAL, see Complex Objects Reference for more information.
MIMETYPE: Optional parameter
xlink:href: The path provided here must be relative to the root of the archive. See the concrete example archive below to evaluate this requirement. Using other values for path will cause the METS to be rejected because the referenced files will not be found inside the archive.
ADMID:
1. If you provide as value the ID of a mets:sourceMD in the METS, the embedded XML under this tag will be used a sidecar metadata for the referenced file. In the example above the values METADATA-SIP and METADATA-PDF refer to matching embedded sidecars in the format MediaHAVEN_external_metadata.
2. If you provide as value the ID of a mets:digiprovMD in the METS, the embedded Premis event under this tag will be recognized by MediaHaven and be visible in the future metadata exports for this file. In the above example the values PREMIS-EVENT-01
  and PREMIS
  and PREMIS-EVENT-02 refer to matching embedded Premis events.
