Online shops can provide valuable information about objects and their properties. The package comp_germandeli contains an OWL ontology that has been generated from the [[http://www.germandeli.com|GermanDeli online shop]], selling German products in the US. It can be loaded into KnowRob and expands the 'objects' branch of the ontology with about 7,000 additional classes. | Online shops can provide valuable information about objects and their properties.

===== Exchanging Information via RoboEarth ===== | ===== Exchanging Information via RoboEarth ===== |
| [[http://www.roboearth.org|RoboEarth]] is a web-based database for exchanging information between robots via the Internet. The content of the database can be searched using a [[http://api.roboearth.org|web interface]] as well as using a [[http://api.roboearth.org/documentation/dev|REST-style API]]. The following examples show some tools that can interact with RoboEarth; the first two are graphical editors that can up-and download information to and from RoboEarth, the latter is a query interface that directly loads the information into KnowRob. |
