The SAS Information Delivery Portal provides access
to the publish and subscribe features of SAS. These features enable
users and applications to publish information to other authorized
users. Information can be published using various delivery methods,
including SAS publication channels, message queues, e-mail, and files.
A publication
channel is a virtual communication path that is identified with a
particular topic, organizational group, user audience, or other category.
A publication channel is similar to a radio channel that is identified
with a particular frequency. Your site administrator defines the publication
channels for your organization. Users who sign up to receive information
from a channel are called subscribers. If you subscribe to a channel,
then you automatically receive information whenever it is published
to that channel.
Using
the SAS Information Delivery Portal, you can do any of the following
tasks:
-
-
Subscribe to one or more channels.
This action involves the following tasks:
-
-
Subscribe to one or
more publication channels that have been defined by your portal administrator.
For details, see Managing Your Subscriptions.
-
Publish information to a publication
channel or to a WebDAV repository.

-
Specify the sort order for packages
that are published in a channel. Packages are listed in order by creation
date.

-
When you
subscribe to a channel, one of the following occurs:
-
If the delivery transport in your
subscriber profile is
Portal, then the channel
is automatically added to your Publication Channel Subscriptions portlet.
-
If the delivery transport in your
subscriber profile is
WebDAV, then channel
content appears in the WebDAV repository.
-
If the delivery transport in your
subscriber profile is
E-mail,
then channel content is e-mailed to you. (You receive e-mail only
for content that is published to the channel using SAS Publishing
Framework. You do not receive e-mail for content that is published
from the portal.)
