<div>Hi Ivan,<br><br>I just looked over your post really quickly. But that quick glance makes me think you are need of one or both of the following modules in addition to nodewords:<br><br>

module can decide to concatenate further meta or define a<br>"owerwriteability" level.<br><br>I gave a look to nodewords aka Meta tags but I have stuff that<br>aren't nodes (they aren't views or taxonomies either) that don't fit<br>
with the node paradigm too well.<br><br>nodewords provide a hook to 'prepare' META but it is on a module<br>base.<br>Nodewords needs to be aware of all the content types (or just pages,<br>menu_hook etc...) it can support (*unless I'm missing something...*)<br>
but actually what know better which are the most suitable meta for a<br>"content" should be the content producer (be it a "node" or just a<br>MENU_CALLBACK).<br>Other modules like nodewords_bypath and _nodetype do some extrawork<br>
to know what actually called the hook.<br>But I'd find myself more comfortable with a different approach:<br>- there is a common API that let me manage META<br>- modules that want to add META use it<br>- when everything is ready drupal_set_html_head get called<br>
<br>The problem is:<br>- the API functions should be ready when other modules call them<br>- drupal_set_html_head($meta) should be called last<br><br>If the weight of my meta module is high, other modules won't find<br>
the functions.<br>If the weight of my module is low and I put<br>drupal_set_html_head($meta) in the menu hook, drupal_set_html_head<br>will be called before $meta had the chance to be filled by other<br>modules.<br><br>I'd say this is a general common problem but I didn't find any<br>
"drupalish" way to solve it.<br><br>The easiest (and somehow elegant) way I thought to deal with this<br>problem was to build up 2 modules with different weight):<br>- meta_prepare (that will offer the functions)<br>
- meta_deliver (that will simply call drupal_set_html_head)<br><br>Is there a more drupalish way to deal with dependency and "order of<br>execution" in drupal?<br><br>thanks<br><br>--<br>Ivan Sergio Borgonovo<br>
