creates
type: ObjectProperty
inverse of: is created in
comment: A relation between a production process (e.g., Batch) that creates one or more tangible objects (e.g., Items)

has size
type: ObjectProperty
comment: A relationship to count the amount of certain objects in a collection (e.g., size of a material batch)

is created in
type: ObjectProperty
comment: An Item is created in an ItemBatch.

needs equipment
type: ObjectProperty
comment: A relationship indicating that an entity needs a particular equipment to be produced

type: ObjectProperty

range: Transform
comment: Indicates the relation between a spatial object and its representation in a 3D scene.

Plastic Bottle
type: Class
subclass of: Item
comment: A plastic bottle is a bottle constructed from high-density plastic.

Plastic Bottle Batch
type: Class
subclass of: Item Batch
comment: A collection of plastic bottles.

Batch
type: Class
subclass of: Restriction
  on property: needs equipment
  all values from: ProductionEquipment
subclass of: Restriction
  on property: has size
  max qualified cardinality: 1
  on class: Size
comment: A uniform collection of tangible objects or Lot. This can either be a collection of produced items (i.e. the outflow of products) or a collection of raw material or required material (i.e. the inflow of products). It is assumed that the objects in a batch are similar and thus have shared attributes. Note that this definition is broader than the definition in IEC 61512, which defines a batch as the material that is being produced (whereas in SAREF4INMA a batch can be items or materials).

Item
type: Class
subclass of: Restriction
  on property: is created in
  all values from: Item Batch
subclass of: Restriction
  on property: is created in
  qualified cardinality: 1
  on class: Item Batch
comment: A tangible object which can be unique identified, for example, with a GTIN in the form of a barcode/QR/RFID tag. An item product can be the result of the organization's production process (i.e. outflow of objects/goods) or can be uniquely identifiable material (i.e. inflow of objects/supplies). Each item is part of exactly one ItemBatch, whereas each ItemBatch contains only Items which have similar properties. An item can consists of multiple Batches and other Items (i.e. subassemblies).

Item Batch
type: Class
subclass of: Batch
subclass of: Restriction
  on property: creates
  all values from: Item
comment: A uniform collection of tangible objects which are relevant for the prodcution process. The ItemBatch consists of a set of objects with similar properties (e.g. a certain type of sensors or metal sheets). The difference between ItemBatch and MaterialBatch is that individual items can be traced in a ItemBatch, whereas this is not possible in a MaterialBatch, meaning that, for example, it is possible to trace the individual metal sheet used in a ItemBatch. This implies that the objects in an ItemBatch have an unique identifier (e.g. a GTIN code in the form of a barcode/QR-code or RFID tag).

Size
type: Class
comment: The amount of certain objects in a collection (e.g., size of a material batch).
