The basic concept behind the DSpace's simple archive format is to create an archive, which is directory full of items, with a subdirectory per item. Each item directory contains a file for the item's descriptive metadata, and the files that make up the item.

archive_directory/
item_000/
dublin_core.xml -- qualified Dublin Core metadata for metadata fields belonging to the dc schema
metadata_[prefix].xml -- metadata in another schema, the prefix is the name of the schema as registered with the metadata registry
contents -- text file containing one line per filename
file_1.doc -- files to be added as bitstreams to the item
file_2.pdf

<element>
- the Dublin Core element<qualifier>
- the element's qualifier<language>
- (optional)ISO language code for element
Code Block |

<dublin_core> <dcvalue element="title" qualifier="none">A Tale of Two Cities</dcvalue> <dcvalue element="date" qualifier="issued">1990</dcvalue> <dcvalue element="title" qualifier="alternatealternative" language="fr">J'aime les Printemps</dcvalue> </dublin_core> |
(Note the optional language tag attribute which notifies the system that the optional title is in French.)
Every metadata field used, must be registered via the metadata registry of the DSpace instance first.
The contents
file simply enumerates, one file per line, the bitstream file names. See the following example:

metadata_[prefix].xml
, where the [prefix]
is replaced with the schema's prefix.<dublin_core>
element include the attribute schema=[prefix]
.Here is an example for ETD metadata, which would be in the file metadata_etd.xml
:
