3.1
component
named and individually scheduled physical item and feature that might require management, such as inspection, maintenance, servicing or replacement, during the in-use phase
Note I to entry: Components can serve as interacting objects in a system (313).

3.2
data dictionary
centralized repository of information about data such as meaning, relationships to other data, origin, usage and format
Note ito entry: The definition is from IBM Dictionary of Computing.

3.3
data template
data structure used to describe the characteristics of construction objects (14)
EXAMPLE 1 A data template provides a view based on an information exchange, e.g. a heating, ventilation and air conditioning (HVAC) system designer is asking for the descriptions of the 1-IVAC products that can he loaded Into the design system.
EXAMPLE 2 A data template provides manufacturers a standardized data structure that can be applied to any internal system and/or process of handling product data, e.g. one or several product information management systems can apply or map to this structure to enable machine readability, both internally and with any requests from any software using the same data template structure. An HVAC product manufacturer can then answer the request from any stakeholder including the HVAC system designer.
Note I to entry: The relevant scope of the data template can be used together with the term “data template. E.g. a data template for a product (9) can be named product data templates. A data template for a system (LU) can be named “system data template”, etc.
Note 2 to entry: A data template can be used in an information exchange for a specific purpose for a construction object in the inception, brief, design, production, operation and demolition of facilities.
3.4
construction object
object of interest in the context ofa construction process
EXAMPLE I The construction object “wall’ is a type of system (11.3).
EXAMPLE 2 The construction object “calcium silicate masonry unit” isa type of product (3,9). [SOURCE: ISO 12006-2:2015, 3.1.2, modified — EXAMPLEs 1 and 2 have been added.]
3-5
enumerated type value
data type consisting of a set of named values called elements, members, enumeral, or enumerators of the type
3.6
globally unique identifier
GUID
unique identifier generated using an algorithm
Note 1 to entry: In ISO 16739-i and ISO 12006-3 the compressed version ot iUID is used. [SOURCE: ISO 23386:2020, 3.13]BS EN ISO 23387 pdf download.
