DSpace METS Document Profile for Submission Information Packages (SIP)

...

DSpace at MIT has implemented the Reference Model for Open Archival Information Systems (OAIS) http://nssdcftp.gsfc.nasa.gov/standards/ccsds/pdf/CCSDS-650.0-B-1.pdf^{Image Removed}. DSpace's implementation has identified a need to prepare a METS profile or profiles that will govern the creation of the three types of content "packages" defined by the reference model.

...

7. Preferred Bitstream = METS <file> element @USE (Structural Requirements #)
There are some potential DSpace Items that are not websites—they websites--they do not have a primary bitstream—that bitstream--that need to show preference for one bitstream or file above all others. One example of this is a potential item that contains three versions of the same document (e.g. pdf, ps and latex). It is advantageous to the user to know that the pdf is the version intended for public consumption. In this case this profile recommends that USE attribute of the <file> element representing the preferred bitstream contain the value "preferred".

...

The following are the necessary component parts of any METS profile conforming to the METS Profile Schema as defined at http://www.loc.gov/standards/mets/profile_docs/components.html^{Image Removed}

These parts are presented first in human readable form, then repeated in an requirements compliant xml expression. The xml expression is governed by the schema at: http://www.loc.gov/standards/mets/profile_docs/mets.profile.v1-2.xsd^{Image Removed}

1.MODS (Metadata Object Description Schema), version 3http://www.loc.gov/standards/mods/v3/mods-3-1.xsd^{Image Removed}
Elements from MODS are used to express descriptive metadata for the DSpace Item and its constituent files.

2.Creative Commons License Schemahttp://web.resource.org/cc/schema.rdf^{Image Removed}
The Creative Commons RDFXML schema is used to capture distribution licenses for the content of METS SIPs.

3.PREMIS Preservation Metadata Schemahttp://www.loc.gov/standards/premis/PREMIS-v1-0.xsd^{Image Removed}
Elements from the PREMIS Preservation Metadata Schema: Object are used to express the DSpace Required Technical Metadata Element Set.

...

1. The official descriptive metadata record for the DSpace Item must conform to the Metadata Object Description Schema (MODS) defined at http://www.loc.gov/standards/mods/v3/mods-3-2.xsd^{Image Removed} .

2. Other metadata records included in conforming METS documents may be expressed in any metadata schemes.

3. Technical metadata for DSpace Items and Bitstreams occurring in the techMD element should conform to the DSpace Required Technical Metadata Element Set defined at http://wiki.dspace.org/index.php/DSpaceMETSSIPProfile^{Image Removed}. This metadata should be encoded using the PREMIS Data Dictionary.

3. The DSpace Content Object Model organizes DSpace Items into Bundles. Bundles are exclusive classifications of files within a DSpace Item.

4. Content files—files files--files intended for the Content bundle—must bundle-must be included in or referenced from the fileSec and the structMap. Metadata files—files files-files intended for the Thumbnail, Text (Extracted), License, CC_License and Metadata bundles—are bundles--are included in or referenced either from the fileSec, dmdSecs or amdSecs.

1. This profile is intended for use with the DSpace Packager Plugin, sometimes called the Lightweight Network Interface and discussed at http://wiki.dspace.org/index.php/PackagerPlugins^{Image Removed}.
