Association moves toward system specification

The LonMark Interoperability Association is expanding its scope to encompass whole systems in addition to individual devices.

The LonMark Interoperability Association is expanding its scope to encompass whole systems in addition to individual devices.

This change simplifies the process of defining open systems by combining guidelines that detail the various tools and functionality that comprise an open system.

Incorporating XML/SOAP web services standard interfaces for machine-to-machine communications will extend the footprint of an open LonMark system providing added benefits to end-users in the form of open procurement (bidding) and vendor independence.

The association's shift to certifying systems builds on worldwide acceptance of the value of LonMark Certified devices to put an end to the debate of "system versus device".

As the market for open interoperable systems grows and more and more specifications are written to include "open systems", it will be possible for an individual to write an industry- or application-independent specification that clearly provides the benefits of open systems to end-users and investors - leading conclusively to the selection of a LonMark system.

The system will then be flexible enough to satisfy the needs of the specifier/consultant, integrator, and the end user.

Currently available for review by LonMark members in the member area of the LonMark Interoperability Association website, the new "system definition" divides the systems description into five categories: system behaviours, devices, connectivity, device interfaces and network software and tools.

Also addressed in the definition is the technique for communicating via the Internet.

This allows data to be reviewed in a standard fashion using web services, such as SOAP and XML.

When defined and finalised, the LonMark web services schema will reside within the oBIX (Open Building Information Exchange) initiative sponsored by CABA, the Continental Automated Buildings Association.

"Moving toward systems and seamless Internet connectivity is the next logical step for the LonMark Interoperability Association", said Barry Haaser, Executive Director of the Association.

"The adoption of LonMark system components will help reduce costs associated with specifying, designing, maintaining and supporting open systems worldwide".
