    therefore not beholden to any group or company whether software suppliers building companies architects or others or indeed governments Open and transparent because the processes by which bSI operates need to be clear and understood by all to demonstrate its independence and neutrality A not for profit organisation meaning that any profits it might make from commercial or quasi commercial activities are used for non commercial purposes such as developing standards The association s goals in pursuit of its mission are To develop and maintain open international standards for Building Information Modelling open BIM To accelerate market assimilation of interoperability through successful sustainable projects To provide networking opportunities specifications and written guidance To resolve high cost problems that hinder data sharing To extend buildingSMART processes and technology to the whole built environment over its lifecycle and encompassing leadership production facilities management and engineering maintenance buildingSMART develops open standards for Building Information Modeling open BIM The standards deal with data models processes and terms The Industry Foundation Classes IFC specification constitutes buildingSMART s specification for the buildingSMART data model Property terms defined in IFC are linked to terms defined in the buildingSMART data dictionary buildingSMART liaises with the International Standardization Organization

  • Introduction
    one or many recognized work flows in the building construction and facility management industry sector Each work flow identifies data exchange requirements that are to be supported by the conforming software applications buildingSMART International publishes official model view definitions and exchange requirements as related specifications The official website for publication of this specification related model view definitions and exchange requirements and supporting materials such as implementer agreements example data sets references to development tools discussion forum and issue database and certification programs is http www buildingSMART tech org The IFC specification includes terms concepts and data specification items that originate from use within disciplines trades and professions of the construction and facility management industry sector Terms and concepts uses the plain English words the data items within the data specification follow a naming convention the data item names for types entities rules and functions start with the prefix Ifc and continue with the English words in CamelCase naming convention no underscore first letter in word in upper case the attribute names within an entity follow the CamelCase nameing convention with no prefix the property set definitions that are part of this standard start with the prefix Pset and continue with the English words in CamelCase naming convention the quantity set definitions that are part of this standard start with the prefix Qto and continue with the English words in CamelCase naming convention The data schema architecture of IFC defines four conceptual layers each individual schema is assigned to exactly one conceptual layer Figure 1 shows the schema architecture Figure 1 Data schema architecture with conceptual layers Resource layer the lowest layer includes all individual schemas containing resource definitions those definitions do not include an globally unique identifier and shall not be used independently of a definition declared at a higher

  • Terms, definitions, and abbreviated terms
    an example of a concept concept template the specification of a subset of the schema structure to enable a certain unit of functionality NOTE The identification of the entities attributes and constraints needed to express a material definition independently on how it is utilized later in the context of a wall is an example of a concept template concept root an entity of a schema used to assign concepts to describe the required functionality NOTE A root concept often describes a model element such as wall air outlet construction task or similar that is the root of a graph of connected entities and attributes defining the specific information items required such as geometry material breakdown structure etc control directive to meet specified requirements such as for scope time or cost NOTE A specialization of the general term object dictionary collection of words terms or concepts with their definition element tangible physical product that can be described by its shape representation material representations and other properties NOTE A specialization of the general term product element occurrence element s position within the project coordinate system and its containment within the spatial structure entity class of information defined by common attributes and constraints as defined in ISO 10303 11 NOTE Similar to the term class in common programming languages but describing data structure only not behavior such as methods external reference link to information outside the data set with direct relevance to the specific information the link originates from inside the data set feature parametric information and additional property information modifiying the shape representation of an element to which it applies group collection of information that fulfills a specified purpose NOTE A specialization of the general term object identification capability to find retrieve report change or delete specific instances without ambiguity instance occurrence of an entity NOTE Similar to the term instance of a class in object oriented programming library catalogue database or holder of data that is relevant to information in the data set NOTE It is information referenced from an external source that is not copied into the data set schema the definition of the structure to organize data for storage exchange and sharing using a formal language NOTE The formal languages EXPRESS ISO 10303 11 and XML Schema W3C Recommendation are currently used to define the schemata of this standard object anything perceivable or conceivable that has a distinct existence albeit not material object occurrence characteristics of an object as an individual NOTE Similar to object instance individual in other publications object type common characteristics shared by multiple object occurrences NOTE Similar to class template type in other publications process object occurrence located in time indicating when product physical or conceptual object that occurs in space NOTE It is specialization of the general term object project encapsulation of related information for a particular purpose providing context for information contained within NOTE Context information may include default measurement units or representation context and precision property unit of information that is dynamically
