way 574903669: how certain are you about "no evidence on the ground"? When had you been there? Google shows a very nice wide paved road there. OSM looked quite up-to-date before you removed the road classification. https://www.google.com/maps/place/15%C2%B034'30.0%22N+102%C2%B026'16.8%22E/@15.575,102.435806,1611m/data=!3m1!1e3!4m5!3m4!1s0x0:0x0!8m2!3d15.575!4d102.438

Ok. in general, we put in the tags what is on the signs. Corner-cases make it a bit more complex here. Signs can have shortened names due to limited space you have to expand. Spelling mistakes can exist on signs and here we suffer from different ways to do transliteration into the Latin alphabet.

I don't know what the "official" transliteration method is. In Thailand it would be RTGS. Not certain for Laos. The official one would be the preferred one for name:en (unless it has it's own English name). If the sign differs it would be good to add this as well in the alt_name:en tag so it can be found when searching for it. Adding something obviously wrong as name:en is a bad idea because the sign might be going to be changed on the next chance. For your notes: "Beu 10 - Ber Sib". Sib is the spoken word for 10. I have the tendency to keep the number as arab numbers. With it being on the sign, this is a good candidate for alt_name:en. The other differing transliterations probably as well, unless the one on the sign from your notes is also the correct official transliteration in which case it should be replacing name:en.

It's been a while since I was in Luang Prabang. I got a few hundred georeferenced photos. With some help I got part of it entered in Lao script as well.

In general I suggest to follow the successful tagging scheme also used in Thailand. Put the local name in Lao script in the name tag. Avoid to shorten the name. Use English name/transliteration in name:en.

If you can't write Lao, put only English. That's fine for a start. If you can take a photo of the Lao script, try to find someone typing it for you.

a variety_store is not the corner shop you wanted to add. shop=convenience is the tag

this is clearly a highway=residential. Why do you tag everything as tertiary?

please stop tagging everything as highway=tertiary

Hello,
please take caution about the classification of highways. The way 570532245 is only a dead-end residential road. A classification as tertiary is wrong. I have corrected it for you.

you added many ways with a temporary highway=road. Please take care to do a correct tagging, otherwise data can't be used in OSM. seems most are agricultural, so highway=track

why was way 504117425 not connected to the main road at the eastern end near the bridge?

way 507348977: leads to farmland. residential not justified

way 526553099:
It might have been fine, that the correctly tagged tertiary highway extends a bit further from the village onwards from the point where the road turned into unpaved. Residential sounded not too bad. Tertiary looks certainly wrong. It is leading only to agricultural areas. So probably highway=track is more appropriate. Why is the way not continued in the west? It is obvious that it continues there. And the different imagery layers support this as well.

roads ragged with temporary type highway=road. Shouldn't they be highway=unclassified as they connect villages? way 568266427
way 568266426
way 568263878

What happened here? A (service?) road leading to the temple tagged as tertiary, nearby highway=road. eg way 568301907

Are you going to revisit that tagging?

why is nearly everything tagged as highway=tertiary? Most of them are clearly not...

While I agree, that way 384629995 is not necessarily an agricultural track, it is certainly no major highway of the arterial network. So highway=tertiary is absolutely unjustified. I'm changing it to a highway=service as it seems the only thing it serves is the cemetery.
In case the area nearby the railway crossing is residential, a highway=residential might be an option as well.

you deleted a lot of highway=* classifications when adding the durface. Did you replace/rename existing tags instead of adding a new one? I fixed some, bout would be nice if you could review the other edits you did during this time to ensure that others got their tags back as well

you repaired some, but for example residential way 559328577 is still tagged as secondary

residential roads are no major highways. please use appropriate tagging

I repaired your bad tagging before. Why are you breaking it again? Are you trying to destroy data? a residential road is no tertiary highway.

Will you fix it yourself?

Do not use highway=tertiary for residential roads. The key "maxspeed" is for tagging signed speed limits. So there has to be an official speed limit sign. It is not used to tag the typical/recommended speed. Please double-check this.
