This falls into the category "Neat things you can do with SMW":
I just added the following code to my wiki:
--- orig/includes/OutputPage.php
+++ mod/includes/OutputPage.php
@@ -1039,6 +1039,11 @@
$ret .= "<meta name=\"keywords\" content=\"" .
htmlspecialchars(preg_replace(array_keys($strip),
array_values($strip),implode( ",", $this->mKeywords ))) . "\" />\n";
}
+ $d = $this->parse('<ask
headers="hide">{{PAGENAME}}[[Kurzbeschreibung:=+]][[Kurzbeschreibung:=*]]</ask>',
false);
+ if ($d != '') {
+ $ret .= '<meta name="description" content="' .
+ htmlspecialchars($d) . "\" />\n";
+ }
foreach ( $this->mLinktags as $tag ) {
$ret .= '<link';
foreach( $tag as $attr => $val ) {
As you can guess, most pages have an attribute "Kurzbeschreibung"
(= short description), which now gets automatically added if it is
available.
I'm still amazed at the cool things SMW enables me to do!
Kudos to all the developers!

PS: This could be made into an extension, so the query is not hardcoded
but can be set via a special page.
PPS: I have no idea how this change interacts with caching. Does anyone
know this?
