Start and end dates
Currently, this page describes that for the attribute "Periodic date start" (PERSTA) the key "start_date" should be used, and that for the attribute "Periodic date end" (PEREND) the key "end_date" should be used. This appears to be incoherent with the way start_date=* and end_date=* are used for other kinds of objects in Openstreetmap. Instead end_date=* and start_date=* look like the appropriate keys for encoding "Date end" (DATEND) and "Date start" (DATSTA). The information contained in the attributes "Periodic date start" (PERSTA) and "Periodic date end" (PEREND) could either be combined into service_times=*, which would be in line with the usage in the rest of OSM, or attached to new keys periodic_date_start=* and periodic_date_end=*. (I'm intentionally proposing service_times=* because a lighthouse might have opening_hours=* for visitors and completely different service times when its light is on.) What do you think? --Biff (talk) 22:28, 30 July 2013 (UTC)
Help for non-experts
This page is clearly full of useful information. However, it's hard to see how to actually use these tags if the reader is not an expert in tagging (or perhaps an expert in openseamap tagging).
Some worked examples would be very useful. Can anyone suggest these?
Ftr, I'm a mostly-inland boat-user, wanting (for completeness) to give the openseamap tags for land-lubber tags like mooring=yes. eteb3 (talk) 20:00, 28 August 2020 (UTC)
- there are numerous JOSM presets making seamark tagging easier. The European inland navigator should have a look at Seamarks/CEVNI Notice Marks and Seamarks/CEVNI Lateral Marks. See also Seamarks/Buoyage Systems and forum.openseamap.org . User:Kannix 2020-08-9)
Category to group seamark tags
I want to ask, which wiki category do you prefer to use to group the seamark tags? E.g. for group in Key/ValueDescription and associated data item.
A consistent specification might be preferable.
At present there are 3 of them mixed in use:
--Chris2map (talk) 08:38, 30 January 2022 (UTC)
- Category:Marine navigation This is already used on central wiki pages for the seamark tagging, especially Seamarks/Seamark_Objects and related pages in Template:Seamarks_seamark_en. The term "navigation" provides some reference to the special purpos of the seamark information as Navigationa aid. Additionally, it gives at least a hint, that it is not only for use at the sea, but navigation in general, which is also relevant at inland waterways. Correspondingly, the inland waterway seamark wiki page Seamarks/CEVNI_Notice_Marks is already using Category:Marine navigation. The Category:Marine navigation will need to be added to Seamarks/INT-1_Cross_Reference.
- "nautical" could be used as term, e.g. as of "nautical chart". At the same time this is also referred to as "navigational chart", again suggesting to use Category:Marine navigation and thereby picking up the navigational purpose of seamark information.

- Category:Marine navigation sounds reasonable to me too. Unfortunately, many tags were provided with the group Maritime. Then they would all have to be updated. --Chris2map (talk) 18:38, 30 January 2022 (UTC)
... let's start together. Do you have a todo list?
- There has to be reviewed every seamark: key or tag, listed on either Category:Maritime or Category:Marine, and changed the specified group= (if so) and also with the related data item. --Chris2map (talk) 20:05, 30 January 2022 (UTC)
