In CMS Fiona, RSS feeds can be generated by
exporting news lists using a layout file that creates the
desired RSS format. The news lists themselves come into
existence by assigning CMS files to channels (using the
channels version field) and then releasing the
CMS files.
Using the NPSOBJ instruction newslist, all
news files or only those that meet particular criteria can
be queried (for example those that have been assigned to
particular channels). Furthermore, the maximum number of
news articles to be retrieved can be restricted.
In CMS Fiona, the following features serve to create news feeds:
In the system settings, channels can be defined. Channels are used for structuring news articles by their topic, i. e. for categorizing or classifying them, just like a user-defined field product-group classifies a file with respect to the products described in the contents of the file. The channel settings can be set via the Extras > System configuration menu item.
The versions of documents and folders have
the built-in field channels. The
channels field’s type is
multi-selection, meaning that any number
of the channels that have been configured can be
assigned to it. In this manner, content is assigned to
the channels.
File formats have the
canCreateNewsItem field (Mark as news on
the live server). If this field has been activated for
a format, the files with this format are added to an
internal news list when they are released, provided
that the version’s channels field is not
empty (meaning that this field contains at least one
channel).
It is possible to create news lists from
files assigned to any combination of channels. For
this, an NPSOBJ instruction and a Tcl command are
available. Analogously to the toclist
instruction, the NPSOBJ instruction returns a context
list, so that the version fields can be queried. The name
of the corresponding Tcl command is
news.
