RSS Channel Example

++++++++++++++++++++

Assuming you have several blog entries, click on the title of the

search box in the left column. A larger search box should appear. Enter:

.. sourcecode:: sql

   Any X ORDERBY D WHERE X is BlogEntry, X creation_date D

and you get a list of blog entries.

Click on your login at the top right corner. Chose "user preferences",

then "boxes", then "possible views box" and check "visible = yes"

before validating your changes.

Enter the same query in the search box and you will see the same list,

plus a box titled "possible views" in the left column. Click on

"entityview", then "RSS".

You just applied the "RSS" view to the RQL selection you requested.

That's it, you have a RSS channel for your blog.

Try again with:

.. sourcecode:: sql

    Any X ORDERBY D WHERE X is BlogEntry, X creation_date D,

    X entry_of B, B title "MyLife"

Another RSS channel, but a bit more focused.

A last one for the road:

.. sourcecode:: sql

    Any C ORDERBY D WHERE C is Comment, C creation_date D LIMIT 15

displayed with the RSS view, that's a channel for the last fifteen

comments posted.

* show that the RSS view can be used to display an ordered selection

  of blog entries, thus providing a RSS channel

* show that a different selection (by category) means a different channel
