S-101 document referencing older versions of ISO 191xx standards

[forodd]

Don't know if this has been brought up before.

One of our "ISO-experts" had a look at the latest version of the S-101 PS (Edition 1.2.0.202301109) and noticed that the list of references in part 1.2 contains references to several ISO/TC211 standards that have been replaced by newer versions.

I know for sure that for some standards this is intentionally done so, but not sure its the case for all.

Some examples he found
ISO 19105:2022, (S-101 references 2000)
ISO 19107:2019 (S-101 references 2003)
ISO 19131:2022 (S-101 references 2008)
ISO 19157-1:2023 (S-101 references 2013)

Not sure this is an issue at all, and maybe not for 2.0.0 anyway, but comments anyone?

Agree this is not a pressing concern, but my comments are:

This should reference S-100 5.1. I don't think the ISO references are necessary unless they are explicitly referenced somewhere in the PS. The reference to S-100 should be enough since S-100 specifies the use of ISO standards:

S-100 normative references

S-101 vs. S-100 references to ISO standards listed in previous message

Standard	S-101 agrees with S-100	Reference in S-100
ISO 19105	Why is this referenced in S-101?	Unreferenced in S-100 other than in "Terms and definitions".
ISO 19107	Yes
ISO 19131	No
ISO 19157	No

I would agree with Dave that we should remove references unless we specifically reference something as S-101 refers to these standards via S-100. A short statement explaining this may be useful. I think one further action here could be to prompt the S-100WG to consider tracking where S-100 is behind the ISO standard and monitoring this, it may be that we choose to stay on the older versions but it should be a considered view.

it may be that we choose to stay on the older versions but it should be a considered view.

In general, the newer standards add a tremendous amount of additional complexity with little benefit to S-100. Their use would impose additional implementation requirements on OEM's.
