Abstract

Open Archives Initiative Object Reuse and Exchange (OAI-ORE) defines standards for the description and exchange of aggregations of Web resources. OAI-ORE introduces the notion of a Resource Map, an RDF Graph [RDF Concepts] which describes the Aggregation, the aggregated Resources of which it is composed, and the relationships between them (and/or the relationships between these and other resources).

Since a Resource Map is an RDF Graph, it can be serialized using any RDF syntax. This document outlines the use of one such syntax for the serialization of Resource Maps: RDF/XML [RDF/XML]. A companion document [ORE RDFa] outlines the serialization of Resource Maps in RDFa [RDFa Syntax].

This document is intended for implementers who have an understanding of ORE concepts and are responsible for the development of applications which generate or process Resource Maps using RDF/XML. Readers who want a high-level understanding of the motivation for ORE, and of the solution it provides, should read the ORE Primer [Primer]; readers who want further details of the RDF/XML syntax should consult the W3C RDF/XML specification [RDF/XML]

This is one of several documents comprising the OAI-ORE specifications and user guides.

1. Introduction

The Open Archives Initiative Object Reuse and Exchange (OAI-ORE) [Abstract Data Model] introduces the notion of a Resource Map, an RDF Graph [RDF Concepts] which describes an Aggregation, the Aggregated Resources of which it is composed, and the relationships between them (and/or the relationships between these and other resources). Since a Resource Map is an RDF Graph, it can be serialized using any RDF syntax.

This document outlines the use of one such syntax for the serialization of Resource Maps: RDF/XML [RDF/XML]. The RDF/XML specification [RDF/XML] describes an XML format for serializing RDF graphs. In order to represent an RDF Graph as an XML document the constructs of the RDF Graph (triples made up of subjects, predicates and objects) have to be represented as components in that XML document, i.e. as XML elements and XML attributes, XML element names and XML attribute names, and as XML element content and XML attribute values.

For some features of the RDF Graph, the RDF/XML syntax permits the encoding of a single feature in multiple ways in XML. The aim of this document is to provide a profile of RDF/XML for encoding an ORE Resource Map. However, it is possible to use RDF/XML to encode the same ORE Resource Map using a different set of conventions permitted by RDF/XML.

1.1 Notational Conventions

The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [IETF RFC 2119].

This specification uses the common term URI to mean both IRI [RFC3987] and URI [RFC3986].

1.2 Namespaces

This specification uses the following namespaces and prefixes to indicate those namespaces:

Prefix Namespace URI Description
dc http://purl.org/dc/elements/1.1/ Dublin Core elements
dcterms http://purl.org/dc/terms/ Dublin Core terms
foaf http://xmlns.com/foaf/0.1/ FOAF vocabulary terms
ore http://www.openarchives.org/ore/terms/ ORE vocabulary terms
rdf http://www.w3.org/1999/02/22-rdf-syntax-ns# RDF vocabulary terms
rdfs http://www.w3.org/2000/01/rdf-schema# RDFS vocabulary terms

1.3 Conformance

The Internet media type / MIME type for RDF/XML is application/rdf+xml. Where RDF/XML is used to provide representations of ORE Resource Maps that media type MUST be used.

A consumer of ORE Resource Maps encoded in RDF/XML MUST support all of the syntactic conventions defined by RDF/XML. This allowance for different syntactic conventions is supported by conformant RDF/XML parsers.

2. Summary of Recommended ORE RDF/XML Syntax

The general convention used in RDF/XML is that the set of subject-predicate-object triples is represented as sequences of XML elements corresponding to the subject of one or more triples (node elements) containing child XML elements corresponding to predicates (property elements) the attributes and/or content of which correspond to the objects. Since the object of one triple may itself be the subject of another triple, that pattern can be repeated, with the consequence that this convention is sometimes referred to as "striping". Neither the order of node elements within the root element, nor the order of property elements within the node element, is significant.

This document describes a convention for encoding Resource Maps in RDF/XML where this striping is limited to one "level" i.e. a node element contains child property elements but those property elements do not contain further node elements.

The exception to this one level striping is when the object of a triple is a "blank node", or "bNode". In this case any subsequent triples where that object bNode is a subject may be nested in the "stripe" corresponding to the subject of the original triple. Note that bNodes are not mandated by the ORE data model, but MAY occur in some triples, for example when asserting the creator of a Resource Map, where no URI is available for the specified agent. Where a bNode is the object of multiple triples (e.g. the same agent is the creator of multiple resources), then two options are available: either the pattern above is repeated for each occurrence of the bNode and the triples where that bNode is a subject are nested in each "stripe", or the bNode is represented as an un-nested node element in its own right.

Also, in the conventions used here, a node element always has the XML expanded name ("http://www.w3.org/1999/02/22-rdf-syntax-ns#", "Description"), typically represented by the QName rdf:Description, where the prefix rdf is associated via an XML namespace declaration with the namespace name http://www.w3.org/1999/02/22-rdf-syntax-ns#. In other words, these examples do not make use of RDF/XML's "typed node element" convention: triples with the predicate http://www.w3.org/1999/02/22-rdf-syntax-ns#type are always represented using property elements.

In the remainder of this document, the names of XML elements are cited as XML QNames. An XML QName is an abbreviation for an expanded name, a pair consisting of an XML Namespace Name (a URI) and a local name. The prefix part of the XML QName is bound to an XML Namespace Name through an XML Namespace declaration; where an XML QName has no prefix, the XML Namespace Name is obtained from the default namespace declaration. Where an XML QName is used to represent a URI in RDF/XML, the URI is determined by appending the local name part of the QName to the XML Namespace Name. For example, using the mapping provided in the section above on Namepaces, the QName ore:describes maps to the URI http://www.openarchives.org/ore/terms/describes. Note that the prefix used in the QNames in this document should not be interpreted as significant; any prefix can be used as long as the QName corresponds to the XML expanded name which would be generated using the prefix/namespace name pairs listed in the section above on Namepaces.

As demonstrated by the examples in the remainder of this document the recommended rules for encoding a Resource Map in RDF/XML are:

3. Examples of Resource Maps Encoded in RDF/XML

The remainder of this section uses the an e-print in arXiv with a "splash page" at http://arxiv.org/abs/astro-ph/0601007 to illustrate the RECOMMENDED RDF/XML encoding of a Resource Map. This is an interesting example because it has multiple identifiers, versions, formats, mirrors and external relationships. For illustrative purposes, the example diverges from the real e-print in arXiv in the manner that it associates an aggregation of data with the e-print.

These examples use the following URIs for the Aggregation (URI-A) and Resource Map (URI-R). As specified, the URI-A of an Aggregation should be distinct from the URI of a splash page.

The ordering of the following subsections correspond to that used to introduce features in the Abstract Data Model specification [Abstract Data Model]. Each section header links to the corresponding Abstract Data Model section. The examples are not intended to be exhaustive, but sufficient to demonstrate the recommended RDF/XML syntax.

3.1 Relationship between a Resource Map and an Aggregation

A Resource Map MUST include one triple with an ore:describes predicate. The subject of this triple MUST be the URI-R of the Resource Map. The object is the URI-A of the Aggregation described by the Resource Map.

The triples corresponding to the example are:

These triples SHOULD be serialized in RDF/XML as follows:

Note: The use of bold in the RDF/XML above indicates the segment of the XML that corresponds to the triples in the table that immediately preceeds the example. This visual cue will be used throughout this document.

3.2 Metadata about the Resource Map and Aggregation

A Resource Map MUST include triples expressing minimal metadata properties about the Resource Map. It MAY include triples expressing additional metadata properties about the Resource Map. Finally it MAY include triples expressing metadata properties about the Aggregation.
