The Industry Foundation Classes, IFC, are an open international standard for Building Information Model (BIM) data that are exchanged and shared among software applications used by the various participants in the construction or facility management industry sector. The standard includes definitions that cover data required for buildings over their life cycle. This release, and upcoming releases, extend the scope to include data definitions for infrastructure assets over their life cycle as well.
The Industry Foundation Classes specify a data schema and an exchange file format structure. The data schema is defined in
- EXPRESS data specification language, defined in ISO 10303-11,
- XML Schema definition language (XSD), defined in XML Schema W3C Recommendation,
whereas the EXPRESS schema definition is the source and the XML schema definition is generated from the EXPRESS schema according to the mapping rules defined in ISO 10303-28. The exchange file formats for exchanging and sharing data according to the conceptual schema are
- Clear text encoding of the exchange structure, defined in ISO 10303-21,
- Extensible Markup Language (XML), defined in XML W3C Recommendation.
Alternative exchange file formats may be used if they conform to the data schemas.
ISO 16739-1:2017 of IFC consists of the data schemas, represented as an EXPRESS schema and an XML schema, and reference data, represented as definitions of property and quantity names, and formal and informative descriptions.
A subset of the data schema and referenced data is referred to as a Model View Definition (MVD). A particular MVD is defined to support one or many recognized workflows in the construction and facility management industry sector. Each workflow identifies data exchange requirements for software applications. Conforming software applications need to identity the model view definition they conform to.

ISO 12006-2:2015 defines a framework for the development of built environment classification systems. It identifies a set of recommended classification table titles for a range of information object classes according to particular views, e.g. by form or function, supported by definitions. It shows how the object classes classified in each table are related, as a series of systems and sub-systems, e.g. in a building information model.
ISO 12006-2:2015 does not provide a complete operational classification system, nor does it provide the content of the tables, though it does give examples. It is intended for use by organizations which develop and publish such classification systems and tables, which may vary in detail to suit local needs. However, if this part of ISO 12006 is applied in the development of local classification systems and tables, then harmonization between them will be facilitated.
ISO 12006-2:2015 applies to the complete life cycle of construction works, including briefing, design, documentation, construction, operation and maintenance, and demolition. It applies to both building and civil engineering works, including associated engineering services and landscaping.

ISO 16757-2:2016 describes the modelling of building services product geometry. The description is optimized for the interchange of product catalogue data and includes
- shapes for representing the product itself,
- symbolic shapes for the visualization of the product's function in schematic diagrams,
- spaces for functional requirements,
- surfaces for visualization, and
- ports to represent connectivity between different objects.
The shape and space geometry is expressed as Constructive Solid Geometry (CSG) based on geometric primitives concatenated to boundary representations by Boolean operations. ISO 16757-2:2016 uses the applicable primitives from ISO 10303‑42 and from ISO 16739 and adds primitives which are required for the special geometry of building services products. For symbolic shapes, line elements are also used.
ISO 16757-2:2016 neither describes the inner structure and internal functionality of the product nor the manufacturing information because this is typically not published within a product catalogue.
Building services products can have millions of variant dimensions. To avoid the exchange of millions of geometries, a parametric model is introduced which allows the derivation of variant-specific geometries from the generic model. This is necessary to reduce the data to be exchanged in a catalogue to a manageable size. The parametric model will result in smaller data files, which can be easier transmitted during data exchanges.
The geometry model used does not contain any drawing information such as views, line styles or hatching.

The primary purpose of ISO 16757 is the provision of data structures for electronic product catalogues to transmit building services product data automatically into models of building services software applications. This includes a meta model for the specification of product classes and their properties and a meta model for the product data which is exchanged in product catalogues. Product data has to follow the specifications for their product groups.
ISO 16757-1:2015 specifies
the underlying concepts,
a generic model specifying the available modelling elements and their relationships, and
a framework for the specification of the Content Parts by describing the elements which are to be provided by these Parts.

This document deals with the processes involved in the procurement and delivery of information to planning and construction projects, specifically with exchange information requirement (EIR) and BIM execution plan (BEP), considering the administrative processes. This document takes into account international standards and specifications as well as recommended practice.
This document is relevant for all parties involved in the tendering of information deliverables. Including both those that require and those that deliver the information. The required information can be relevant for all processes in the life cycle such as design, construction, operation and maintenance and end-of-life processes. It applies above all to e.g. client, asset owners/operators, architects, engineer, contractors, subcontractors etc.
This document provides methodology to appointing parties on how to require and agree the right amount, quality and level of information needs.
It is also important for appointed parties to be able to assess the quality of existing EIRs and identify possible over-specification or gaps. Based on this, it is possible to estimate and calculate the necessary effort for data creation.
This document operationalizes the tendering and appointment process of information deliverables as specified in EN ISO 19650-2:2018. This document does not cover all clauses of EN ISO 19650-2:2018. Its main goal is to provide template examples and guidance for all activities conditioning specification of requirements and deliverables in the production of exchange information requirements and BIM execution plan. Specifically, it covers the “shall” and “shall consider” requirements in EN ISO 19650-2:2018, 5.2.1 (EIR), 5.3.2 (pre-appointment BEP) and 5.4.1 (confirmed BEP).

This document defines an open and stable container format to exchange files of a heterogeneous nature to deliver, store and archive documents that describe an asset throughout its entire lifecycle.
It is suitable for all parties dealing with information concerning the built environment, where there is a need to exchange multiple documents and their interrelationships, either as part of the process or as contracted deliverables. The format is intended to use resources either included in the container (such as documents) or referenced remotely (such as web resources). A key feature is that the container can include information about the relationships between the documents. Relevant use-cases reflect the need for information exchange during the entire life cycle of any built asset and can include, but are not limited to, the handover of
- a published bidding package,
- required project deliverables at a specific project stage (e.g. when proposing different design scenarios),
- shared information as background or for further development,
- published approval packages, or
- information about versions between partners to provide a means to reference particular states of the information and track changes.

This document discusses an integrated and unified approach for data aspects, specifically for assets in the built environment, using EIF terminology.
The following data architecture (Figure 1) applies within each category.
Figure 1 - Data architecture with typology (grey areas indicating the scope of this document)
...
This document specifies:
-   a generic Top Level "M1: Data model" as common form;
-   a conceptual "L1: Data language" as common meta-model with four ‘linked data’-based concrete language bindings (SKOS, RDFS, OWL and SHACL), including:
-   a choice of RDF-based formats (to be used for all modelling and language levels);
-   a set of data modelling patterns (for identification, naming, handling of enumeration types, quantity modelling, asset decomposition, grouping, etc.).
-   a linking approach for interlinking data sets, interlinking data models and linking data sets and data models which are relevant within the built environment from many perspectives such as:
-   Building information modelling (BIM);
-   Geo-spatial information systems (GIS);
-   Systems engineering (SE)  );
-   Monitoring & control (M&C);
-   Electronic document management (EDM).
This document does not specify a knowledge model since this is already available in ISO 12006-3.
This document does not specify a meta-‘data language’ since this is already provided by the concrete RDF language bindings (being RDFS).
The scope of this document in general excludes the following:
-   Business process modelling;
-   Software implementation aspects;
-   Data packaging and transportation/transaction aspects (handled by ISO TC59/SC13 Information container for document delivery (ICDD) respectively various information delivery manual (IDM) / information exchange requirements (EIR)-related initiatives);
-   Domain-specific (here: built environment-specific) content modelling in the form of concepts, attributes and relations at end-user level (the actual ontologies themselves) beyond a generic upper ontology and modelling patterns.

ISO 19650 part 4 provides detailed process and criteria for the decision points in the process of executing an information exchange within information management as defined by ISO 19650. It promotes a sustainable approach to information exchange where the immediate delivery of information does not preclude its future use.    
It is applicable to any information exchange within project stages (ISO 19650 part 2) and within in-use events (ISO 19650 part 3).  All development and information exchanges should be executed under the appropriate security controls (ISO 19650 part 5).
It supports the satisfaction of a specific EIR/AIR related to an individual information exchange of any type of information by enumerating criteria relating to completeness, compliance to formal exchange schemas, the continuity of concepts between exchanges and the elimination of spatial and specification conflicts
