@aorzelskiGH @BirgitBoss I have added two more questions, also hiddnen ID's for the question for an easy tracibility.

Furthermore, in practical implementations we advise to “filter” out protocol and schema for comparing IRI identifiers. For example, following IDs should be considered equal:
- https://admin-shell.io/some_id_example
- http://admin-shell.io/some_id_example
- ftp://admin-shell.io/some_id_example

Idea was to ignore the protocol-specific schema to make implementation practical

**How to refer to semantic concepts of existing standards like VDI 2770 properties or OPC UA companion specifications (e.g. “Serial number” property from OPC UA DI companion spec)?** <!-- ID: 27, 28 -->
Map concepts to “admin-shell.io” namespace (see [custom identifier best practices](#id18)). Within the concept description itself use “sourceOfDefinition” or “isCaseOf” to link to “original” concept.

The link custom identifier best practices is very strange... does not jump to the question but to complete FAQ list. It seems to me that the labels id18 etc. were only introduced in comments and thus are not effective?

Examples of several suppliers are found at: http://admin-shell-io.com/samples/
