But a river is flowing water and is often rendered differently, and tagging as natural=water risks losing this information invisibly, if the water=river tag is accidentally or intentionally deleted - this is partially the fault of OpenStreetMap-Carto for not yet rendering any difference between rivers and standing water. </div><div><br></div><div>-- Joseph Eisenberg</div></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Dec 13, 2020 at 9:49 AM Tomas Straupis <<a href="mailto:tomasstraupis@gmail.com">tomasstraupis@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;border-left-color:rgb(204,204,204);padding-left:1ex">2020-12-13, sk, 19:18 Mateusz Konieczny via Tagging rašė:<br>

Mateusz, can you point out which of my claims is a lie?<br>
I didn't say iD invented duplicate schema, I said that schema was<br>
lying dead until iD decided to introduce it as the only way to tag<br>
water, introduction "launched" new water schema adding any<br>
considerable usage (as it was the only option for iD mappers).<br>
<br>
Introducing duplicate and unused schema (especially as the only<br>
option) is not a good IT decision, basic analysis should have shown<br>
that. But in case of id it was technology leading functionality and<br>
thus leading users when in IT it must be the other way round -<br>
usage/requirements must lead technical decisions. That is IT BASICS.<br>
Lack of such understanding is the reason why I claim iD developers<br>
lacked basic IT knowledge.<br>

<br>
Key word "introduced" so it is 2012, not 2019.<br>
water=reservoir usage in 2012 is close to zero.<br>

<br>
The author of this proposal agreed that standard water schema is NOT<br>
deprecated. And a few people voting in wiki cannot deprecate a tag.<br>
Only people actually mapping can do that.<br>

Do not copy/paste my words in random order and you will not get such<br>
claims from me :-)<br>
<br>
Anyways, there is no way I will be able to teach IT things people<br>
who do not want to learn. Let's not rewrite the history of this saga<br>
and lets move forward instead of repeating the same discussion again<br>
and again. Let's do what is possible so that this does not happen<br>
again:<br>
<br>
* When tagging schema CAN be changed and when it CAN NOT?<br>
* What ADVANTAGES are required to allow deprecating current schema?<br>
