Hydra is affilliated with the following programs and organisations:

The Hydra coordinater FhG FIT is a member of ARTEMISIA, the association for R&D actors in the field of ARTEMIS: Advanced Research & Technology for EMbedded Intelligence and Systems.

The Hydra middleware allows developers to create inclusive applications with a high degree of accessibility for all. The Hydra project supports the Commissions campaign: eInclusion - be part of it!

The Hydra project is part of the Cluster of European projects on the Internet of Things. The Cluster aims to promote a common vision of the Internet of Things.

Hydra enabled devices
Physical devices are the cornerstone of any application intending to implement the Hydra middleware. Any application using external devices such as energy meters, light control switches, blood pressure monitors, etc., will need to interface with the device through its communication interface, which will be greatly facilitated by using the Hydra middleware.

In the Hydra middleware we use the following terms:

Hydra-Compliant Physical Device
A “Hydra-compliant Physical Device” is a physical device that can be Hydra-enabled. Hydra-compliant physical devices divide into 5 different classes that determine the procedure to be used to Hydra-enable devices and integrate them into a Hydra network. In the least class, such devices need to offer some external interface for communication and control. Examples of such external interfaces supported by the Hydra middleware are Bluetooth, ZigBee, RF, RFID, serial ports, USB, etc.

Hydra-Enabling a Device
“Hydra-enabling a Device” means the process of making the functions of a Hydra-compliant physical device available and controllable for other devices in a Hydra network. Depending on its device class, three methods make such a device Hydra-enabled:
  • installing (parts of) the Hydra middleware on the device,
  • using the Service Compiler tools to embed Web Services on the device and generate a Proxy
  • using a Proxy to represent the device on a Gateway
At the end of this process the functions of this device can be invoked using Web Services, and metadata about the device is provided in the format and protocol required by Hydra.

Hydra-Enabled Device
A “Hydra-Enabled Device” is a Hydra-compliant physical device that has successfully run through the Hydra-enabling process. A Hydra-enabled device owns a software representation, i.e. a Hydra Device, in a Hydra network and
  • can be discovered by other devices in a Hydra network,
  • makes all or a subset of its functions accessible as Web Services,
  • offers its Web Services either natively (embedded code) or through a proxy,
  • supports UPnP and advertises its entry into a Local Area Network through UPnP broadcasting,
  • supports Hydra Generic Services and Hydra Energy Service.
At the time of writing (October 2010) the following 42 devices have been Hydra-enabled:
