4.4 Complete schema
Where the information requirements are satisfied by a BIM, a complete information schema that covers all of the information required for all actors throughout the construction process will be large and comprehensive. Such a schema is relevant in defining all of the project information needs for all business processes at all life cycle stages, but it is not the way that project information is usually delivered.
4.5 Breaking a complete schema to support requirements
It is more usual for information to be exchanged about a particular topic and the level of detail provided to be driven by the life cycle stage. This may be a single business process at a specific point in the project life cycle, but commonly consists of in formation units that may be relevant to more than one life cycle stage or business processes. This is commonly referred to as a model view and is a matter of deciding which components of the information schema should be used to meet requirements.
4.6 Supporting the building information modelling process
Elements of the overall information schema are used in a building information model (see Figure 2). For a particular business process, only certain classes of information are required. Multiple objects are derived from each class, each object having an identity (determined by a unique identifier) and a state (determined by the values given to each attribute of the object). The classes that support the business process form a unique and identifiable standard schema or model view.
5.2.3 1DM component overview
Each 1DM component shall start with a short plain language description of the contents, use case, aims and scope that the component is intended to address or about which particular topic or business requirement information shall be exchanged.
Examples of simplified 1DM components are given in Annex 13.
5.3 Interaction map/transaction map
The purpose of an interaction map is to identify the relevant roles and transactions for a specific purpose, typically the completion of a team-based project task. 1DM draws a distinction between a role that makes a request (initiator) and the role that gives effect to that request (executor). If there is such a required communication between two roles, then it is termed a transaction.
The approach recommended to prepare an interaction map is according to the CRISP Model (Dietz, J.L.G.: Enterprise Ontology, Springer, 2006).
In an interaction map, all transactions needed for the handling of required contributions of relevant roles to the BIM shall be included. All transactions within the interaction map have a unique identity and name.AS ISO 29481.1 pdf download.
