<h2><a name="description">Description</a></h2>
|
|
|
|
<p>
|
|
Provides syndication hints to aggregators and others picking up this
|
|
RDF Site Summary (RSS) feed regarding how often it is updated.
|
|
For example, if you updated your file twice an hour, updatePeriod
|
|
would be "hourly" and updateFrequency would be "2". The
|
|
syndication module borrows from Ian Davis's
|
|
<a href="http://InternetAlchemy.org/ocs/">Open Content Syndication (OCS)</a>
|
|
directory format. It supercedes the RSS 0.91 skipDay and skipHour elements.
|
|
</p>
|
|
<p>
|
|
<em>updatePeriod</em><br />
|
|
Describes the period over which the channel format is updated.
|
|
Acceptable values are: hourly, daily, weekly, monthly, yearly.
|
|
If omitted, daily is assumed.
|
|
</p>
|
|
<p>
|
|
<em>updateFrequency</em><br />
|
|
Used to describe the frequency of updates in
|
|
relation to the update period. A positive integer indicates how many
|
|
times in that period the channel is updated. For example, an
|
|
updatePeriod of daily, and an updateFrequency of 2 indicates the
|
|
channel format is updated twice daily. If omitted a value of 1 is
|
|
assumed.
|
|
</p>
|
|
<p>
|
|
<em>updateBase</em><br />
|
|
Defines a base date to be used in concert with updatePeriod and
|
|
updateFrequency to calculate the publishing schedule. The date
|
|
format takes the form: yyyy-mm-ddThh:mm
|
