Talk:Key:seamark:name

Is there any justification to reinvent and duplicate tag name?

For example - is there any good reason to use "seamark:name=5N" instead of "name=5N"? Mateusz Konieczny (talk) 12:51, 2 August 2015 (UTC)

I've verified that neither OpenSeaMap nor JOSM's OpenSeaMap display seamark:name=*, not even when name=* is missing. Also, iD does not support it. 4 out of the 60 OpenSeaMap presets for JOSM use seamark:name=* only, all others (the vast majority) use name=* only. So, seamark:name=* is probably an ancient leftover that could be moved to other name tags such as official_name=* to facilitate geocoding using standard tools such as Nominatim.

I think "5N" is probably a ref=* code, not a name. However, OpenSeaMap does not display ref=*, nor does the standard layer for unnamed elements that can be combined with sea marks (eg. sea lights and man_made=lighthouse). I think they should support it, but the combination is not very common. In my area near  Lagoa dos Patos, whenever a sea mark has both a name and a reference code, official nautical maps represent it in the format "Name (code)", and when there's only a reference code, it's only "(code)".

Also in my area, ref=* in sea marks seems to represent a database record identifier. If that's right, it should be moved into a more specific tag identifying the data source, as is usually done with other kinds of data imports in OSM. Also, seamark:name=* is being used for the name displayed in official nautical maps, while name=* is a shortened, more standardized version of it that fits nicely into OpenSeaMap.--Fernando Trebien (talk) 19:58, 1 March 2019 (UTC)

@Malcolmh: - in https://wiki.openstreetmap.org/w/index.php?title=Key:seamark:name&curid=99243&diff=2184554&oldid=2184550 you claim that "The "ref" for a seamark object would be the catalogue number in the lists published by navigation authorities." - how it exactly differs from ref=* tagging? Mateusz Konieczny (talk) 07:40, 8 August 2021 (UTC)

Hello @Mateusz Konieczny: I did a test too and got different results. OpenSeaMap only renders seamark:name=*, not name=*. Example - only one of the three lights has seamark:name=*, and that's the only one that's rendered. --Kylenz (talk) 00:30, 6 November 2021 (UTC)

@Kylenz: it is not a good justification, see Tagging for the renderer. It seems that OpenSeaMap should be fixed to use standard tags rather than duplicating them Mateusz Konieczny (talk) 06:31, 6 November 2021 (UTC)

I totally agree, I personally will be using name=* and description=* instead of seamark:name=* and seamark:information=*. Just worth pointing out that OpenSeaMap currently doesn't support the two standard tags --Kylenz (talk) 07:00, 6 November 2021 (UTC)

While I don't like it, you should look at it together with seamark:national_name=*.

I'm more annoyed by not using ref=5 for the seamark:name=5 example here.

Effort to document difference from, and use with, name

When tagging something like seamark:type=bridge for the benefit of water-based navigation, there are a bunch of seamark-tags that apply. seamark:name=* is one of them. There a number of details I would like to improve the documentation of:

• The documentation currently says that the value of this tag should not be a description, similar to how name=* is used. I've seen this tag (ab)used in this manner though. There is no corresponding seamark:description=*. What is the guideline for moving descriptive names to a more suitable tag?

• How should (seamark-)items that have no name (like some bridges) be tagged? Can noname=yes be used?

• Another point that could use clarification: what is the relation with name=*? Should name=* be used together with this tag, or only when they differ?

• @Malcolmh: You added this phrase “This name is often different from the local customary name, which would be used for the "key:name" tag.”. How and when is this tag's value different from that of name=*?

"There is no corresponding seamark:description=*. What is the guideline for moving descriptive names to a more suitable tag?" - see ATYL, you are free to fix mistaggings, also when it needs creation of new tags Mateusz Konieczny (talk) 00:09, 25 December 2021 (UTC)

"Should name=* be used together with this tag, or only when they differ?" - if object has name then it should be tagged in name=* Mateusz Konieczny (talk) 00:10, 25 December 2021 (UTC)

1. seamark:information=*.
2. Likely no Seamark equivalent.
3. They are separate. Use both. One difference seen in Key:seamark:name#Names_of_Navigation_Objects is this will get seamark:name=5, while the ordinary OSM standard would be ref=5. This tag is defined as "The unique identifier of a navigation object.".
4. Should use seamark:national_name=* for that.
