{{Short description|Archival standards}}

'''The [[Open Archives Initiative]] '''Object Reuse and Exchange''' (OAI-ORE) defines standards for the description and exchange of aggregations of [[Webweb resource]]s. The OAI-ORE specification implements the '''ORE Model''' which introduces the [[Resourceresource Mapmap]] (ReM) that makes it possible to associate an identity with aggregations of resources and make assertions about their structure and semantics.

These aggregations (sometimes called ''[[compound digital object]]s'' or ''compound information objects'') may combine distributed resources together, and with multiple media types including text, images, data, and video. The goal of OAI-ORE is to expose the rich content in aggregations to applications that support [[authoring]], deposit, exchange, [[Information visualization|visualization]], reuse, and [[digital preservation|preservation]].

== Introduction ==

The ORE standard is concerned with the description of aggregations of web resources. It defines 4 entities:

* the Aggregation itself, identified by its [[URI]] but without any corresponding concrete resource. It is a conceptual resource. Being uniquely identified it can enter into relationships with other resources, in particular aggregations of aggregationaggregations become possible.

* the Aggregated Resource: any resource part of an aggregation, identified by its URI

* the Resource Map: a resource describing an aggregation based on a set of assertions. A mandatory assertion indicates which aggregation the Resource Map itself is describing. Other assertions indicate the aggregated resource(s). Certain metadata are mandatory as well, such as the map creator. [[Dublin Core]] terms are used for this purpose.

Line 16 ⟶ 17:

The standard is open in the sense that a Resource Map may include any additional assertions about resources.

Finally, the ORE standard builds upon the ''Cool URIs ''<ref>[http://www.w3.org/TR/cooluris Cool URIs for the Semantic Web ] (W3C Interest Group Note)</ref> guideline, which discussed two strategies for not confusing a thingsthing and some representation of it.
