# Transformations

|
|
|

|
|
The following rules have been applied in order to create PDDL files from IEC 62264 production system models.
|
||
|
|
|
||
|
|
## Metamodel Concepts
|
||
|
|
Metamodel concepts of IEC 62264 are being converted to a set of PDDL type specifications and predicates. Relevant elements are those that appear within a given IEC 62264 model. Unused elements are not translated in order to reduce file size and increase performance and readability.
|
||
|
|
* IEC 62264 elements (e.g., `Equipment`, `Equipment Class`) are being converted to types.
|
||
|
|
* IEC 62264 relations (e.g., `Equipment` can be classified by [0..*] `Equipment Classes`) are being converted to predicates.
|
||
|
|
|
||
|
|
For the above mentioned examples, the IEC 62264 concepts are being translated from
