<div>I strongly disagree.</div>
<div><br>
</div>
<div>It is perfectly useful to document the existence of tags in the database with data items. For example one was created for the key sub_sea:type [https://wiki.openstreetmap.org/wiki/Item:Q4506] and it has been possible to add this it is a discardable tag
that the main OSM editors remove when editing. While it is possible in principle to add a long form tag documentation page, and indeed the presence of the data item is a record that one may be worth writing, it needs a different set of skills to research its
content. As such the data item and others like it are useful on their own.</div>

<b>Subject:</b> [OSM-talk] Creation of "Data Items" by bot for undocumented tags</font>
<div> </div>
</div>
<div class="BodyFragment"><font size="2"><span style="font-size:11pt;">
<div class="PlainText">Data Items should not be created by bot for undocumented tags.<br>
<br>
According to <a href="https://wiki.openstreetmap.org/wiki/Data_items#Item_Creation_Process">
https://wiki.openstreetmap.org/wiki/Data_items#Item_Creation_Process</a><br>
the Data Items (aka "Wikibase" or "Wiki Data items") are automatically<br>
created by a bot, even before a tag is documented, if a tag has a<br>
certain standard format and more than 10 uses in the database.<br>
<br>
The data item is created in this case with the text "ıCreated a new<br>
Item: Auto-updating from Wiki pages" - e.g.<br>
<a href="https://wiki.openstreetmap.org/w/index.php?title=Item:Q19947&action=history">https://wiki.openstreetmap.org/w/index.php?title=Item:Q19947&action=history</a><br>
<br>
This is confusing to users. For example, Item:Q19947 above,<br>
"landuse=research" was created before there was a wiki page. Then<br>
yesterday a user documented the tag with a page, but did not<br>
understand why there was already a data item:<br>
<br>
"Wikibase entry: evidence for preceding deletion? I've just created<br>
landuse=research, but the data item<br>
<a href="https://wiki.openstreetmap.org/w/index.php?title=Item:Q19947&action=history">https://wiki.openstreetmap.org/w/index.php?title=Item:Q19947&action=history</a><br>
was already existing in December '19. How was the data item then<br>
created?"<br>
<a href="https://wiki.openstreetmap.org/wiki/Talk:Wiki=#Wikibase_entry:_evidence_for_preceding_deletion.3F">https://wiki.openstreetmap.org/wiki/Talk:Wiki=#Wikibase_entry:_evidence_for_preceding_deletion.3F</a><br>
<br>
Besided the potential confusion caused by creating these items by<br>
bots, I think it is a bad idea to encourage wiki users to start<br>
editing these data items without first creating an actual<br>
human-readable wiki page to document the tag.<br>
<br>
In theory, the "Data Items" can be useful if they properly document<br>
how tags are used, in a way that is easier for computers to handle,<br>
but this only works if the data is maintained and updated.<br>
<br>
Creating a new wiki page (by human) will alert other users via<br>
"Special:Recent" and "Special:NewPages", while the stream of items<br>
created by bots is too much for humans to maintain, and the page names<br>
are too obscure (Item: Q19947 is meaningless) to be scanned by humans.<br>
<br>
Therefore, I propose that Yurikbot be changed to only add new data<br>
items for documented tags which already have a wiki page in at least<br>
one language. I do not see a benefit to creating date items for<br>
undocumented tags.<br>
