Hi Alex, Hugh,

You can use our API to query the db using a DBpedia (or Freebase etc.)
identifier. Here an example (for Barack Obama):

http://news.ontos.com/api/ontology?query={"get":"attrents","offset":0,"limit
":30,"typeFilter":"http://www.ontosearch.com/2008/02/ontosminer-ns/domain/co
mmon/english#Person",
"attrnames":["http://www.ontosearch.com/2008/02/ontosminer-ns/domain/common/
english/dbpedia#sameAs"],"attrvals":["http://dbpedia.org/resource/Barack_Oba
ma"]}

Just now you have to know the Ontos type for doing this, i. e. you have to
match DBpedia types to Ontos types by yourself. We are planning to extend
this functionality in order to make this more simple.

You can of course use our API to make queries by object name or fulltext and
use resulting objects as "starting points" for exploring the db, i. e. to
find additional ones. Also see Kingsley's hint.

Regards,
Christian
