### Basisprofil DE
The Basisprofil DE project contains the national German profiles created by HL7 Germany. The project also contains a couple of derived profiles that change the slicing of their base profile. Below are some examples.

#### Example 1 - Constraining slices

The profile shown below is a derived profile based on the German base Patient profile. The derived profile is meant for use in the context of German insurance core data management (VSDM, eGK-Datensatz). The slice `VersichertenID_GKV` (on `Identifier`) already exists base profile. In the derived profile, its minimum cardinality is set to 1.

#### Example 2 - Constraining slices

Another example is the coverage-de-khentgg-strict profile, a Coverage profile derived from the German coverage-de-gkv profile. In this profile the maximum cardinality of the `Krankenversichertennummer` and `PseudoVersichertenID` slices (on `Identifier`) is set to 0 as these slices are not used in this specific context.

#### Example 3 - Adding slices

Finally, in the patient-de-geronto profile (a Patient profile derived from the German patient-de-vsdm profile) additional slices are added on `Identifier` (e.g. `geronto-pid` and `geronto-teleid`).

### Core specification
#### Nested slicing
The core specification contains a couple of profiles on Observation to capture different measurements, such as blood pressure. The core profile for blood pressure (http://hl7.org/fhir/StructureDefinition/bp) contains nested slices. First, the `component` element is sliced to obtain two separate slices for Systolic Blood Pressure and Systolic Blood Pressure. Next, the `coding` element is sliced to obtain a specific slice with a fixed system and code.
