---------------------------------------
Summary: Atom Taglib: tag attribute requirements to do not reflect
standard's definition
Key: SLING-3671
URL: https://issues.apache.org/jira/browse/SLING-3671
Project: Sling
Issue Type: Improvement
Components: Scripting
Affects Versions: Scripting JSP-Atom-Taglib 1.0.0
Reporter: Christoph Dahlen
The current
[TLD|http://svn.apache.org/repos/asf/sling/trunk/contrib/scripting/jsp-taglib-atom/src/main/resources/META-INF/atom.tld]
for the Atom taglib allows creating Atom Feeds that do not meet the standard's
requirements.
Most simple example:
{code:xml}
<atom:feed><atom:entry /></atom:feed>
{code}
will create the following output
{code:xml}
<feed
xmlns="http://www.w3.org/2005/Atom";><updated>2014-06-16T12:39:03.382Z</updated><entry
/></feed>
{code}
This output fails to [validate|http://validator.w3.org/feed/] due to missing,
but mandatory elements "id" and "title" for _feed_ and _entry_ and missing
element "updated" for _entry_.
According to http://atomenabled.org/ the required elements for both
[feed|http://atomenabled.org/developers/syndication/#requiredFeedElements] and
[entry|developers/syndication/#requiredEntryElements] are:
* id
* title
* updated
Enforcing this requirements would require the following changes:
# make the "id" attribute required for _feed_ and _entry_ element
# either
## make the "updated" attribute required for _feed_ and _entry_ OR
## auto-compute the updated attribute for _entry_, as it is obviously done for
the _feed_ element
# replace the "title" element by a "title" attribute for _entry_ and _feed_ and
make it mandatory.
Comments on the feasibility are very welcome.
