Re: Problem extending SilvaNews

Hi Pierre,

You can use the same scheme, adding your custom metadata, e.g.:

scheme = 'http://infrae.com/namespaces/metadata/silva-news'
meta_template = (
    '<meta scheme="http://infrae.com/namespaces/metadata/silva-news" '
    'name="%s" content="%s" />')
metas = []
if hasattr(version, 'teaser'):
    content = entitize_and_escape_pipes(version.teaser_editable())
    metas.append(meta_template % ('teaser', content))

The scheme is only used to identify during processing what set of metadata the 
value belongs to.  This allows you to extend the properties with your own 
metadata sets.

I have patched SilvaNews to provide support for a teaser, a display method 
(default, full content, lead_paragraph, lead paragraph + image, teaser, 
teaser + image), external link (news item just appears in viewers and links 
to content elsewhere), and a link method (none, external link, article).

The version of SilvaNews my modifications are based on is 2.1.1.  If you're 
interested, I can send it along.

It also has support for "news images".  News Images are assets that can be 
attached to a news item, and include keywords.  You can have multiple news 
images for a news item, perhaps keyed on 'intranet', 'external site', "25px 
by 50px", etc.  News Viewers can be configured to display "news images" with 
certain keys.  So, you can have a news viewer that displays only "25px by 
50px" images, or one that specifically displays images approved for your 
intranet.  Kupu has also been patched to include a "news images" tool to 
manage these.

Let me know if you're interested.

Andy
