UHM use cases¶

tvbruits.org¶

TvBruits is an independant Internet TV. They publish documentaries as :

• Flash videos inside articles (example : http://tvbruits.org/spip.php?article994 )
• Mp3 attached to articles (example : http://tvbruits.org/spip.php?article997 )
• Allow syndicating of articles only.

We want a podcast which merges all these media.

We define a channel that :

1. Fetch tvbruits RSS articles and their attachments
2. Extract videos from the articles
3. Publish a new RSS (with one enclosure per article, so we split).

Here is the XML definition :

<?xml version="1.0" ?>
<channel>
    <node id="rss tvbruits" type="SourceRSS">
        <parameters>
            <parameter name="url" value="http://tvbruits.org/spip.php?page=backend"/>
        </parameters>
        <options>
            <option name="download" value="False"/>
        </options>
        <arrow to="web2attch"/>
    </node>
    <node id="web2attch" type="ExtractEmbedded">
        <arrow to="split"/>
    </node>
    <node id="split" type="AttachmentSplit">

Transform topic-only feeds to full-text version¶

An example with the Nova radio website, having several topic-only feeds. We merge them and populate their summary with webpage relevant text.

The http://feedex.net website provides such a service, but inserts advertisements.

Populate Netvibes activities items with original RSS summary¶

Netvibes activities is a feature of Netvibe which allows you to share RSS items in a feed. By default, Netvibes activities feeds have empty summary. This channel populates summaries with original RSS summaries.

For each item :

1. open the link
2. look for RSS feeds references in the web page
3. look for the link in the RSS feed. If found, get its summary
