Die Deutsche Kreditwirtschaft (DK) is an industry association of the German banking industry.
The available validation services for the payment types specified by the DK are based on schemas published by DK. The schemas are ISO 20022 based but they include some SEPA restrictions.
In addition to the schema, the service also contains the business rule checks derived from the implementation guides published by the DK. The detailed information about the versions of the schemas and implementation guides can be found by selecting an item from the list below.Read more

However, some business rules specified in the DK implementation guide are derived from general level specifications, like ISO20022 or EPC, and in these cases the wiki pages made for these organisations are often used instead.
All German implementation guides can be found from: http://www.ebics.de/index.php?id=77
