buildingSMART Data Dictionary, OmniClass, and Open Standards-Based BIM...

Course Description As they design and construct buildings, professionals need to work in an interoperable fashion with each

other. But how do different software applications talk to each other? And to a product database? Or a

specification system? How can a designer be sure that the engineers understand the attributes attached

to his design? Or that product searches yield reliable results?

The buildingSMART Data Dictionary is a catalog of object names (the ‘vocabulary’) with the capacity to

comprehend multiple languages and alternate terminology in dealing with those objects, and to relate

those objects to properties and other data that can be used to describe those objects, providing a

common way of viewing a construction project or asset. The Data Dictionary fits into the suite of Open

BIM standards provided by buildingSMART International that are the universally accepted methodology

for interoperable model and data exchanges.

The Data Dictionary is based on a concept laid out in in an ISO standard -- 12006-3: 2007 (Building

construction: Organization of information about construction works, Part 3: Framework for object-oriented

information). Through the Data Dictionary, an open BIM model can be linked to data from many sources,

improving interoperability and paving the way for analysis and design checks from the early stages of the

project through the full life cycle.

CSC CONFERENCE 2014 – TAPPING THE FUTURE

Learning Objectives At the end of this program, participants will be able to:

1. Identify what the buildingSMART Data Dictionary is.

2. Understand how OmniClass and the Data Dictionary are related and work together

3. Understand the latest developments in OmniClass

4. Identify how the buildingSMART Data Dictionary may be used in a BIM project.

5. Understand the concept of an open BIM and the role that the buildingSMART Data Dictionary plays in an open BIM.

• How are they used?

First: What is buildingSMART? • buildingSMART International (bSI) is a neutral,

international not-for-profit supporting the worldwide use of openBIM

• The key elements of bSI work: – tools and standards enabling use of common terminology – developing an 'open' file format for storing data – creating processes and protocols for sharing information – certifying compliant software applications


buildingSMART Standards


IFC Model – create a comprehensive information

specification

Data Dictionary – uniquely identify properties and

objects / dynamically extend the IFC model

Exchange Requirements - IDM – define information requirements and

rules for particular business processes

Product Room Members


Product Room Steering Committee members:

The Problem • Control of name space – users identify objects

differently – firms, disciplines, regions, languages • Result: DISCONNECTS • How to resolve?


• Option 2: buildingSMART Data Dictionary (bSDD)

– Pro: Machine enabled, allows for use of natural language variations

– Con: Requires implementation in software

Currently best, most scalable and consistent solution to this common problem


The Solution?

What is the buildingSMART Data Dictionary?

• An open library of object types (concepts, properties, standards, etc.) used in the building industry

• A web service for establishing relations and accessing uniquely identified content

• Works with IFC and IDM

• Based on ISO 120006-3:2007

• Owned and operated by bSI with participation from organizations and chapters around the globe

OmniClass™

So what is OmniClass?

→15 table faceted classification system

→In development since 2001

→North American in focus

→Designed to classify concepts in all types of construction through the full facility life cycle


OmniClass™ and bSDD • Advantages to OmniClass from bSDD

and vice versa – bSDD provides context and relationships

to OmniClass classifications – OmniClass will provide means to organize

and analyze bSDD content – OmniClass will help introduce and

promote bSDD to users in US and Canada – bSDD helps introduce and promote

OmniClass outside US and Canada


Why Classification? Classification Uses:

– Storage – Retrieval – Analysis – Presentation

Classification’s value comes from the order it provides to information – the “human-facing side of BIM”


Classification Basics →Classification is the grouping of like

concepts and their arrangement into a hierarchy – broader concepts (parents) to narrower concepts (children)

→Two basic types:

Enumerative Faceted


Enumerative Classification All concepts are arranged in a single hierarchical listing

→More traditional and common (Dewey Decimal, Library of Congress)

→Considered easier to use →Fundamentally “flat” architecture →More prone to conflict →Less flexible


Enumerative Classification

Faceted Classification Concepts are arranged in multiple parallel hierarchies that view the subject area from a variety of perspectives or “facets”

→Individual tables tend to be smaller and simpler

→Multi-table architecture makes it far more useful in databases

→Far more flexible →Less prone to conflict →Less commonly used →Sometimes difficult for users
