ExtruOnt
A relation between a production process (e.g., Batch) that creates one or more tangible objects (e.g., Items)
A relationship to count the amount of certain objects in a collection (e.g., size of a material batch)
A relationship indicating that an entity needs a particular equipment to be produced
Indicates the relation between a spatial object and its representation in a 3D scene.

A plastic bottle is a bottle constructed from high-density plastic.
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).
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).
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).
The amount of certain objects in a collection (e.g., size of a material batch).
