What is OpenSpime? (Documentation available here: http://openspime.org/what )

The OpenSpime protocol is a set of custom XMPP protocol extensions. The OpenSpime Core protocol defines the XMPP protocol extension that can be used to enable physical devices to communicate.

The OpenSpime protocol consists of:

• the core protocol itself, which is an extensible Extensible Mark-up Language (XML) container;
• the core protocol extensions, i.e. a set of extensions which extend the core protocol, and are already available to be used for a series of functionalities.

As just said, the OpenSpime core protocol is a container, and a container only, which takes care of essential security and practical issues, regardless of the content which is transmitted over the OpenSpime network. More in particular, it allows to:

• encrypt the content sent between two entities (end-to-end encryption);
• digitally sign the content sent between two entities;
• claim the authority to perform operations in the name of another entity.

This means that encryption, digital signature and management rights are taken care of once and for all at core protocol level. On top of this, it is then possible to build extensions which take advantage of these to build X-internet functionalities.

The OpenSpime protocol already comes with 3 protocol extensions (therefore known as core protocol extensions), which allow:

• data reporting from an entity to another entity;
• SpimeSeek, i.e. the process which allows to seek for entities’ data across the network;
• claiming, i.e. the mechanism which authorizes an entity of the OpenSpime network to perform trustful operations in the name of another entity which has allowed it.

What is the vision behind OpenSpime, and what are the requirements and prerequisites for the Internet Of Things?
