3 Terms, definitions and abbreviated terms

3.1 Terms and definitions

3.1.1 Terms defined in ISO 10303-1

For the purposes of this document, the following terms defined in ISO 10303-1 apply:

3.1.2 Terms defined in ISO 10303-41

For the purposes of this document, the following terms defined in ISO 10303-41 apply:

3.1.3 Other terms and definitions

For the purposes of this document, the following terms and definitions apply:

3.1.3.1
ancestor node

any node that can be reached from a given node, by successive traversals of links in the reverse direction.

EXAMPLE    For a given node, its ancestor nodes include all parent nodes, all parent nodes of these parent nodes, etc.

3.1.3.2
bill-of-material (BOM) data structure

graph of data elements that depict a bill-of-material structure

NOTE    See annex for examples of bill-of-material data structures.

3.1.3.3
bill-of-material (BOM) structure

description of the structure of a product in terms of its nested constituents

NOTE    See annex for examples of bill-of-material structures.

3.1.3.4
child node

node to which a link is pointing

3.1.3.5
configuration item

subdivision of a product, either a component or an assembly

3.1.3.6
descendant node

any node that can be reached from a given node, by successive traversals of links

EXAMPLE    For a given node, its descendant nodes include all children nodes, all children nodes of these children nodes, etc.

3.1.3.7
directed acyclic graph (DAG)

collection of nodes and links such that no node is an ancestor (or descendant) of itself

3.1.3.8
effectivity

characteristic that indicates whether a product is allowed, approved, or permitted to be used in another product

3.1.3.9
form, fit, and function

collection of characteristics that include the shape of a product, the way it interfaces with other products, and the purpose that the product serves

3.1.3.10
leaf node

node that has no children

3.1.3.11
link

uni-directional relationship from one node to another node within a directed acyclic graph

3.1.3.12
lot

batch

collection of distinct products that are treated as a single unit

EXAMPLE    Three thousand bundles of yarn are divided into different groups. Each group is submerged in a separate barrel of red dye. The group is treated as a lot and assigned a lot number. The lot number is identified so that conditions causing slight changes in the colour are differentiable among bundles belonging to different lots. A customer may wish to purchase bundles of the same lot to ensure consistency of the colour.

3.1.3.13
node

element of a directed acyclic graph, connected to other such elements by links

3.1.3.14
parent node

node from which a link is initiated

3.1.3.15
parts list data structure

graph of instances that depicts a parts list structure

NOTE    See annex for examples of parts list data structures.

3.1.3.16
parts list structure

description of the structure of a product in terms of a hierarchy of all distinct usages of its constituents

NOTE    See annex of examples for cases of parts list structures.

3.1.3.17
promissory use

intention to use a constituent in an assembly

3.1.3.18
root node

node that has no parents

3.1.3.19
tree

restricted type of directed acyclic graph in which there is only one root node, and in which each node has at most one parent

3.2 Abbreviated terms

For the purposes of this document, the following abbreviated terms apply:

URL uniform resource locator
BOM bill-of-material
CM configuration management
DAG directed acyclic graph
