Developing Feeds with RSS and Atom

Name

mod_company

Synopsis

mod_company allows RSS feeds to deliver business news metadata. Like mod_audio, this is another example of RSS 1.0 stretching the bounds of RSS functionality; this module could lead to RSS being used as a specialist business news vehicle rather than just a generalized list of links.

Namespace

mod_company takes the namespace prefix company: and is identified by the URI http://purl.org/rss/1.0/modules/company. By now, you’ll realize that this means the root element of a RSS 1.0 document containing mod_company will resemble this:

<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
          xmlns="http://purl.org/rss/1.0/"
          xmlns:company="http://purl.org/rss/1.0/modules/company/">

Elements

mod_company provides four elements, all of which are subelements of item. None are defined as mandatory, but there’s little hassle and much reward in including all of them.

company:name

The name of the company.

company:symbol

The ticker symbol of the company’s stock.

company:market

The abbreviation of the market in which the stock is traded.

company:category

The category of the company, expressed using the Taxonomy module. For more details, see mod_taxonomy later in this chapter.

Example

<item rdf:about="http://www.example.com/financial_news/00001.html">
    <title>Cisco Stock moves either up or down!</title>
<description>A brief story about a thing happening today</description>
<link>http://www.example.com/financial_news/00001.html<link>
   <company:symbol>CSCO</company:symbol> ...
