Content Syndication with RSS

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 of them 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.
