RSS-CB 1.1

Abstract

RSS-CB is an extensible metadata description and syndication format, tailored to the needs of central banks and related organizations. RSS-CB conforms to the RSS 1.0 specification, and therefore to the RDF and XML specifications as well. It also uses elements from the Dublin Core and qualified Dublin Core specifications.

Syntax

Following is a description of the elements and attributes that constitute a valid RSS-CB document:

XML declaration

An RSS-CB document begins with an XML declaration.

Syntax:
<?xml version="1.0"?>
Requirement: Required

<rdf:RDF>

The RDF element is the root element, and immediately follows the XML declaration. This element includes the declaration of required and optional custom namespaces. Required namespaces are RDF, RSS, Dublin Core elements, and Dublin Core terms. Declaration of the RSS-CB namespace is expected but not required. Both individual institutions and groups of institutions may promote custom namespaces.

Syntax:
<rdf:RDF
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns="http://purl.org/rss/1.0/"
xmlns:dc="http://purl.org/dc/elements/1.1/"
xmlns:dcterms="http://purl.org/dc/terms/"
xmlns:cb="http://www.cbwiki.net/wiki/index.php/Specification_1.1"
xmlns:onecb="http://www.particularcentralbank.gov/rss/">
Requirement: Required


The RDF element in RSS 1.0 has four child elements. In RSS-CB, two are required, one is optional, and one is prohibited. The permitted child elements must appear in the order shown below.

<channel> Required; one occurrence only
<image> Optional; at most one occurrence
<item> Required; at least one occurrence

Custom namespaces

RSS-CB is extensible through custom XML namespaces. This permits institutions to employ elements and attributes that are specific to their own dissemination needs or to dissemination needs held in common by a group of institutions.

<channel>

In RSS 1.0, the <channel> element has six child elements. In RSS-CB, four are required, one is optional, and one is prohibited. The permitted child elements must appear in the order shown below. There is also one required attribute, about.

<title> Required; one occurrence only
<link> Required; one occurrence only
<description> Required; one occurrence only
<image> Optional; at most one occurrence
<items> Required; one occurrence only
<textinput> Prohibited

Requirement: Optional, but required if higher-level image element is present.

<items>

The <items> element contains a sequential list of URIs, which must match those of the <item> elements contained in the RSS-CB file. The match is between rdf:about attribute of an <item> and the rdf:resource attribute in the list of <items>.

Syntax:
