Resource Map

A Resource Map (ReM) is a concept of ORE Model allowing to associate an identity with compound digital objects (aggregations of digital resources) and make assertions about their structure and semantics. Compound objects combine distributed resources together, including multiple media types.

ReM Serialization

A Resource Map may be serialized (or represented) in several different formats including Atom feeds, RDF/XML, RDFa, and others.

The example below illustrates how a ReM can represent the arXiv e-print at http://arxiv.org/abs/astro-ph/0601007 using an Atom feed. Metadata such as the digital object identifier, title, and authors for the e-print are included first in the Atom feed. The e-print is a compound digital object composed of five aggregated resources which are listed next: OAI-PMH metadata about the e-print, a splash page, a PostScript version of the e-print, a PDF version, and a gzipped tar file containing multiple versions of the e-print.
