The policy schema is a way to capture permission and policy information belonging to DSpace objects into a policy.xml
file. It provides a one-to-one mapping to the ResourcePolicy
object on a DSpace object. The hierarchy is as follows:
policies
elementpolicy
- a ResourcePolicy serialized as an XML tagXML Attribute, ResourcePolicy field name, name type, rpType group, group action, action (represented as a String) eperson, ePerson#getEmail end-date, endDate start-date, startDate description, rpDescription |
The following is an example policy.xml
which belongs to a single DSpace object. It contains 4 policies: one for a custom group, one for the Administrator gorup, one for the Anonymous group, and one for an EPerson.
<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <policies> <policy action="ADMIN" group="COMMUNITY_hdl:123456789/1_ADMIN"/> <policy start-date="2010-01-01" action="READ" group="Anonymous"/> <policy start-date="2010-01-01" action="ADMIN" group="Administrator"/> <policy type="TYPE_CUSTOM" eperson="dspace-user@localhost.localdomain" action="Add"/> </policies> |
The metadata.xml
contains information about the DSpace object, typically user generated. The hierarchy is as follows:
metadata
elementvalue
element - corresponds to the MetadataValue
for the DSpace object or information captured from the object itself; described below for each applicabl DSpace objectFor Communities, the following fields are translated to the metadata schema:
XML Attribute, Database Field name, name short_description, short_description introductory_text, introductory_text copyright_text, copyright_text side_bar_text, side_bar_text |
For Collections, the following fields are translated to the metadata schema:
XML Attribute, Database Field name, name short_description, short_description introductory_text, introductory_text provenance_description, provenance_description license, license copyright_text, copyright_text side_bar_text, side_bar_text |
For Items, the following fields are translated to the metadata schema:
XML Attribute, MetadataValue Field language, MetadataValue#getLanguage qualifier, MetadataValue#getMetadataFeild#getQualifier element, MetadataValue#getMetadataField#getElement schema, MetadataValue#getMetadataField#getMetadataSchema#getName |
For Bitstreams, the following fields are translated to the metadata schema:
XML Attribute, Bitstream Field name, name source, source description, description sequence-id, sequenceID bundle-primary, true if the Bitstream is equal to Bundle#getPrimaryBitstream |

For Items or other objects which contain Bundles and Bitstreams, a directory is created for each Bundle under which Bitstreams are collected. Each bitstream is stored using a prefix of `bitstream_`, the uuid of the Bitstream, and a file extension if it can be derived. e.g. for a Bundle ORIGINAL
and Bitstream with a uuid 46f383da-15d7-423e-bd76-741d9c503d0f will be stored under data/ORIGINAL/46f383da-15d7-423e-bd76-741d9c503d0f
.
If a DSpace Object contains a logo, it is written directly under the data directory using the same filename format as Bitstreams.
