Rivendell has the ability to manage multiple RSS audio feeds, including
|
|
capabilities for posting and expiring audio automatically as well as updating
|
|
associated cast metadata.
|
|
|
|
|
|
CREATING AND POPULATING RSS FEEDS
|
|
--------------------------------
|
|
Setting up a new RSS feed is a matter of accomplishing the following steps:
|
|
|
|
1) Create and configure the feed in RDAdmin
|
|
|
|
2) Schedule the audio posts by means of one or more Upload Events in RDCatch.
|
|
|
|
3) Manage the metadata in RDCastManager.
|
|
|
|
We'll cover each of these steps in turn.
|
|
|
|
|
|
1) Creating RSS Feeds
|
|
Base parameters for each RSS feed are configured in RDAdmin->ManageFeeds. The
|
|
'CHANNEL VALUES' section shows metadata values that will be common to the feed
|
|
as a whole (as opposed to specific podcasts within it). The other parameters
|
|
are used as follows:
|
|
|
|
Key Name - A unique name, eight-characters or less in length, used to
|
|
identify the feed within Rivendell.
|
|
|
|
Audio Upload URL - This is the URL of the directory to which the audio
|
|
files will be uploaded. It is also the URL that the
|
|
system will use when deleting expired audio from the
|
|
system (e.g. by means of an FTP 'DELETE' command);
|
|
hence the specified 'Username' and 'Password' should grant
|
|
sufficient rights to allow contents in the directory
|
|
to be deleted. Currently supported protocols are
|
|
'file:', 'ftp:' and 'smb:'.
|
|
|
|
Audio Download URL - This is the URL of the directory from which the audio
|
|
files will be downloaded. The URL listed should be
|
|
world-readable by 'anonymous' users. Often, this will
|
|
be the same as the 'Audio Upload URL' above.
|
|
|
|
Enable AutoPost - If enabled, each new cast in the feed will become
|
|
'visible' immediately following upload, using the
|
|
default metadata as configured in the channel values.
|
|
If not enabled, then all new casts are placed on hold
|
|
pending the customization of the metadata for the
|
|
particular cast in RDCastManager.
|
|
|
|
Audio Extension - The file extension to use for files posted to the feed
|
|
(default: 'mp3'). NOTE: when using a non-default value,
|
|
it is necessary to manually create a corresponding
|
|
symbolic link on the web server running the 'rdfeed.xml'
|
|
script with the appropriate extension that points to the
|
|
script. For example, if using an extension of 'aac', one
|
|
would do:
|
|
|
|
cd <rd-bin-dir>
|
|
ln -s rdfeed.xml rdfeed.aac
|
|
|
|
Max. Shelf Life - Sets the maximum period (in days) that a piece of audio
|
|
can be set in RDCastManager to remain in the feed until
|
|
purged. If set to 'None', then no limit is enforced.
|
|
This value also establishes the default expiration date
|
|
for each cast (with 'Off' resulting in no expiration
|
|
date being set --i.e. the cast remains TFN).
|
|
|
|
|
|
|
|
XML Data Fields - The various 'XML' fields contain customizable templates that
|
|
Rivendell uses to construct the actual XML code that goes into the RSS file.
|
|
The following variables are automatically substituted on-the-fly when the XML
|
|
is rendered by the 'rdfeed.xml' script:
|
|
|
|

|
2) Posting Audio
|
|
Once the RSS feed(s) are set up, individual podcasts can be added by
|
|
scheduling one or more Upload events in RDCatch. To associate a given upload
|
|
to a particular feed, simply select the desired feed in the 'RSS Feed'
|
|
control of the Edit Upload dialog, being sure that it gets uploaded to the
|
|
location specified in the 'Audio Base URL' for the feed. RDCatch will
|
|
automatically add the audio to the feed's XML file after the upload.
|
|
|
|
|
|
3) Editing Podcast Metadata
|
|
The metadata for individual podcasts (including the cast's expiration date and
|
|
posting status) can be edited by means of the RDCastManager module. Operation
|
|
of the module should be largely self-explanatory.
|
|
|
|
|
|
POSTING THE RSS FEED FILE
|
|
-------------------------
|
|
The RSS file for each feed is generated dynamically by the RDFeed
|
|
script. The specific location of the script is determined by the value
|
|
given in the '--libexecdir=' parameter to './configure' (see the
|
|
'INSTALL' file for more details) and will also be influenced by the specific
|
|
configuration used by the web server. A typical link would looks as
|
|
follows:
|
|
|
|
http://www.example.com/rd-bin/rdfeed.xml?TEST
|
|
|
|
This link would serve the RSS file for the feed with the Key Name 'TEST'.
