Hi,
which app do you mean?

- The LOC dataspace at http://loc.openlinksw.com/sparql supports xml, 
json, html, etc.
- Yahoo BOSS supports XML with RDF/XML as one subnode, and a feed format.
- The GoodRelations Search demo at 
http://goodrelations-search.appspot.com/ is an early prototype that 
currently supports only inspecting the Yahoo index. Thus, the output is 
HTML only. If you want structured data, simply invoke the Yahoo BOSS 
interface directly. This is very straightforward:
   START ="0"
   QUERY ="cars"
   query = urllib.quote_plus(QUERY)
   uri = 
("http://boss.yahooapis.com/ysearch/web/v1/%s?appid="+APPID+"&format=xml&view=searchmonkey_rdf&start=%s") 
% (query, START)
   yahooresult = urllib.urlopen(uri)

You can then extract the RDF data collected by Yahoo:

   dom = minidom.parse(yahooresult)
   results = []
   elements = dom.getElementsByTagName('result')
   for hit in elements:
        abstract = hit.getElementsByTagName('abstract')
        if len(abstract) == 0:
            abstract = "No abstract available. "
        else:
            abstract = abstract[0].firstChild.data
        clickurl = hit.getElementsByTagName('clickurl')[0].firstChild.data
        dispurl = hit.getElementsByTagName('dispurl')[0].firstChild.data
        rdf = hit.getElementsByTagName('searchmonkey_rdf')[0]
        rdf = rdf.getElementsByTagName('rdf:RDF')
        if len(rdf) == 0:
            rdf = "No RDF Found"
        else:
            rdfdata = rdf[0].toxml()
            rdfdata = parseRDF(rdfdata.encode('ascii', 'replace')) # 
TODO: Find better solution for non-ascii content in RDF
            rdf = "RDF metadata found (%d statements)" % len(rdfdata)

   
You need a Yahoo APP ID, which is available for free.

Best
Martin
