Thank you all for your explanations. I'm sad that this is a mistake in the doc :-) because as you pointed out S57 spec has no GUID definition. With the combination of the LNAM + DSNM, it allowed to have one that would be convenient in a PostGIS database that contains many S-57 charts.
On my fork of GDAL I add this attribute DSNM (as defined in the previous documentation), and since the DSNM field is mandatory in the S57 spec I did not detect any problem. (Tested with several S57 source US, UK, ES, HR, ... ) In case it would be helpful, I could make a PR. -- loïc > On 3 May 2020, at 12:49, Even Rouault <[email protected]> wrote: > > On dimanche 3 mai 2020 09:54:22 CEST kusala nine wrote: > > DSNM is dataset name.
