Using RSS and Atom to Access a Voyager Index

Voyager supports Atom and RSS, along with extensions for geospatial content (GeoRSS) and Media (MRSS).

RSS

You can use the following queries to return information via RSS.

• This example will return the entire index:
  http://localhost:8888/feed
  
  

• This example will return content matching the text query “vegas”
  http://localhost:8888/feed?q=vegas
  
  

• This example will return datasets using a spatial constraint:
  http://localhost:8888/feed?&bbox=-93.5156+-38.6719+42.8906+44.2969&bbox.mode=WITHIN
  
  

• This example will return items which have a subtype of raster:
  http://localhost:8888/feed?f.subtype=Raster
  
  

• Any of the above queries can be combined. For example raster datasets which match the text query of “vegas”:
  http://localhost.com:8888/feed?q=vegas&f.subtype=Raster
  
  

• By default, the georss:box element is written as [xmin ymin xmax ymax]. This can be in conflict to applications that expect [lat lon lat lon]. To flip the coordinates to [lat lon lat lon], add ?flip=true to the query string:
  http://localhost:8888/feed?q=vegas&flip=true

Atom

• To use the Atom format, change the URL to:
  http://localhost:8888/feed/atom.xml?q=vegas

This can also be returned as json (or jsonp)

• http://localhost:8888/feed/atom.json?q=vegas

• http://localhost:8888/feed/atom.jsonp?q=vegas&jsoncallback=myfunction
