Freebase RSS Feed Generation

This Freebase app automatically generates an RSS feed from any query. 
The resulting RSS feeds are Media RSS and Geo RSS compatible.
Interesting examples of how to use these feeds are listed below.



API details:

  URL:http://rss.avh.user.dev.freebaseapps.com/feed.xml
  query:Any MQL query (JSON or RISON encoded).
  title:Title for RSS feed, optional.
  service:Freebase service, default is http://www.freebase.com
  image:Either required, omit, fill, or optional, default is optional.
  article:Either required, omit, or optional, default is omit (fetching each article can get slow).
  location:Either required, omit, or optional, default is optional.





 RSS Feed

Enter an MQL query and click the RSS button to generate the corresponding RSS feed:



  
    title:
    
  
  
    query:
    
        
{
   "type": "/music/album",
   "artist": "Abba"
}
        
    
  
  
    
    
      image:
        
          required
          omit
          fill
          optional
        ,
      article:
        
          required
          omit
          optional
        ,
      location:
        
          required
          omit
          optional
        
    
    
  






 Piclens

Piclens is a cool 3D photo viewer which takes a Media RSS feed as input.

Here are some examples of links which generate a Media RSS feed using a MQL query and feed it into the Piclens viewer:

Females,
Males,
Beatles Albums,
Podcasts,
Countries,
Visual Arts.

(Note: these links do not work in the Acre appeditor, you must open this page in a new window.)

Here are instructions on how to embed a Piclens link on your website:


    <script type="text/javascript" src="http://lite.piclens.com/current/piclens_optimized.js"></script>
    <script type="text/javascript">
    function ShowPicLensQuery(query)
    {
        var feed = "http://rss.avh.user.dev.freebaseapps.com/feed?image=required&query=" + escape(query);
        if (PicLensLite.hasClient()) {
            PicLensLite.start({"feedUrl":feed});
        } else {
            alert("Please install PicLens first!");
            window.open("http://www.piclens.com", "_new");
        }
    }
    </script>
    <a href="javascript://females"
       onclick="ShowPicLensQuery(this.title);"
       title="(type:/people/person,gender:Female)">Female Persons</a>


Or try your own PicLens query:



  
    query:
    
      
{
   "type": "/common/topic",
   "timestamp": null,
   "sort" : "-timestamp"
}
      
    
  
  
    
    
  






 GeoRSS

Here is an example of how a MQL query can generate a GeoRSS feed which 
contains longitude and latitudes for each entry. The results are displayed using Google maps. 
For example:
US States,
Dutch Provinces,
Museums,
Big Cities,
California Counties

  Hangliding Sites




 GreaseMonkey

GreaseMonkey is a Firefox extension which can dynamically enhance existing web pages.
To make the above RSS tools easily accessible from the existing Freebase filter pages you can install
this GreaseMonkey script:

fbrss.user.js.
