##  Handle System - RDF Schema for Handle Data Model

##  This document presents an RDF Schema for the Handle System - see
##  RFC 3651 [1]. This is the authoritative reference for the Handle
##  Data Model. For ease of linking, however, this schema refers to
##  the HTML version of the RFC [2]. For further information on the
##  Handle System, see [3].

<!-- "Handle" class -->
<s:Class r:ID="Handle">
  <s:label>Handle</s:label>
  <s:comment>A handle is a globally unique name for an Internet
	resource. Handles are character strings that consist of two parts:
	a naming authority, followed by a unique local name under the naming
	authority.</s:comment>
</s:Class>

<!-- "HandleValues" class -->
<s:Class r:ID="HandleValues">
  <s:label>HandleValues</s:label>
  <s:comment>A set of values assigned to a handle.</s:comment>
  <s:subClassOf r:resource="&rdf;Collection"/>
</s:Class>

<!-- "HandleValue" class -->
<s:Class r:ID="HandleValue">
  <s:label>HandleValue</s:label>
  <s:comment>A handle value is a record that consists of a set of data
	fields: "Index", "Type", "Data", "TTL", "Permission", "Timestamp",
	"Reference".</s:comment>
</s:Class>

<!-- "HandleReference" class -->
<s:Class r:ID="HandleReference">
  <s:label>HandleReference</s:label>
  <s:comment>A handle reference refers to another handle value in terms
	 of a UTF8-string and a 4-byte integer (where the UTF8-string is the
	 handle name and the integer is the value index). For convenience a
	 handle reference is implemented as a URI-ref using the "info:" URI
	 scheme, where the handle value index is referenced in the fragment
	 identifier. For example, a handle reference to the handle
	 "10.1045/may99-payette" with index value "100" will be implemented
	 as the URI "info:hdl/10.1045/may99-payette#index=100".</s:comment>
