In a previous post, I described how vCards are used throughout standards-based scheduling and calendaring systems. Many different vCard standards coexist in today’s organizations. I also described how directory services, especially LDAP (the Lightweight Directory Access Protocol), are the well-established means to enable wide secure access to the information in vCards. In this post I discuss current efforts that will expand these existing standards to support buildings and their systems.

Work Plan for oBIX 2.0
Some of you know that the oBIX Committee (open Building Information Exchange) is meeting again. The work is moving ahead on multiple fronts. We have separated encodings (XML and COAP) from the core specification. We are working on separate transport specifications for SOAP and REST (including JSON). We are doing a refresh of the core specification for consistency and conformance. I am most excited, however about the oBIX 2.0, the enterprise services.
The core specification (1.x) requires each oBIX server to provide a lobby. Clients can ask the server what is in the lobby, and thereby discover how to interact with the system behind that server. Contracts are special purpose agreements...
Slim BIM: The Middle Ground between Document and Service Part 2
In my last post, introduced Slim BIM and the critical need for shared configuration to speed development in the building systems. This post extends that conversation.
A report from NREL, delivered last Spring, defined the Building Service Interface (BSI), a standard for interacting with building systems from non-building applications. That report recommended that each BSI be able to share a light-weight BIM, i.e., ...
Using COBIE as an integration interface
At the meeting of the NIBS FMOC in Baltimore this spring, challenges in expanding the use of COBIE were again at center stage. The National Institute of Building Science (NIBS) is a public-private partnership to advance the identification and resolution of problems and potential problems that hamper the construction of safe, affordable structures. In recent years, one NIBS committee has led efforts to develop a national building information models standard (NBIMS). NBIMS is more than technology, and concerns far more than a 3D building model; BIM it is the basis for re-engineering the processes used in facility design and construction.
The Facilities Maintenance and Operations Committee (FMOC) of NIBS promulgates best practices in building operations. BIM has traditionally focused on initial building cost. Initial cost, though, is only 15 to 20%...
