Re: [IOT] Semantic searches in registry

Hi Johannes, Thanks for your response! An important design principal I had when I wrote the proposal was that I did not want to force a database technology if someone would implement the spec. This was the major reason for me not to use RDF or SPARQL in the spec. The spec should be implementable on other technologies as well. Of course this principal is up for discussion. Choosing a technology would probably simplify the protocol and extend usage options (allowing more complex queries). What do you think about this? Also I have a more specific question on the example you provided. Is there a way to 'pre-define' namespaces in XMPP? They way I see it is the XML stream is opened upon connection and there is no way to add namespaces on the go hence the usage of the 'xmlns' attribute to switch to a specific context.
