Warning! This is just a place-holder while I investigate whether its practical to register a MIME-type.


EPData XML is a recursive structure where an object is represented by a root element named as the dataset-class e.g. eprint becomes <eprint>. Each object may contain zero or more elements representing a single metadata field each e.g. eprint.title becomes <title>. A metafield may be of type Subobject in which case it will contain embedded objects.

Multiple metadata values are represented by zero or more <item> elements directly below the metadata field element.

   <item>{basic XML type or complex value}</item>
</DATASETID + 's'>

Note: we may change the root element to be a generic term to allow a mixture of dataset-classes.

IETF-Registration Draft

Media Type Name: application

Subtype name: vnd.eprints.data+xml

Required parameters: None

Optional parameters: charset

Same as charset parameter of application/xml as specified in RFC 3023.

Optional parameters: files

"files='embed'" can be used during content negotiation to request files be
embedded in the resulting XML.

Encoding considerations:

Same as encoding considerations of application/xml as specified in RFC 3023.

Security considerations:

In addition to those of application/xml as specified in RFC 3023, section
10; the format may contain URL-references that are retrieved and embedded in
the resulting digital object. If the EPrints recipient is configured to
allow it these URLs may be retrieved from remote systems (via HTTP) or the
recipient's file system. This behaviour is only intended for use with trusted
input (e.g. migration of complete installs).

Interoperability considerations: None

Published specification: http://wiki.eprints.org/EPData_XML_Representation

Applications which use this media type: EPrints http://www.eprints.org/

Additional information: Same as additional information of application/xml as
specified in RFC 3023.

Intended usage: Limited Use

XML serialisation of EPrints Data (or "EPData") for the import/export of the
complete record. This is used e.g. for ingesting the results of XSL
transforms from standardised XML formats. The mime-type is necessary to
support correct content-type negotiation when using the EPrints REST
interface although the client will require knowledge of the instance's

Author/Change controller:
