Best practice for exposing, sharing, and connecting pieces of data, information and knowledge on the Semantic Web using URIs and RDF.
Publishing data in RDF format.
Independent of any ontological detail or inference.

Use URIs as names for things
Use HTTP URIs so that people can look up those names.
When someone looks up a URI, provide useful information, using the standards (RDF)
Include links to other URIs; so that they can discover more things.

OpenID is a decentralized standard to authenticate the user.
It has the benefit that the user can chose any method or procedure to provide authentication credentials.
Based on Single Sign On (SSO).

Domotic Gateway Controller (DGC).
Provide ability to access Device Properties.
Provide ability to control Devices.
Internet enabled.
Access through a DGC URL.

Requirement: No network constraint.
Assumptions:
– Access to the master DNS handling reference domain.
– Solution: A CNAME entry aliasing UAID with the DGC Controlling it.
