<p>Hello everyone,</p>
<p>Minh NGuyen had the following remark <a moz-do-not-send="true"
href="https://wiki.openstreetmap.org/wiki/Talk:Tag:cycle_network%3Dcycle_highway">on
the wiki</a> about the current tagging scheme of the cycle
highways.<br>
<br>
Anyone any thought on it?<br>
</p>
<p><br>
</p>
<h2><span class="mw-headline" id="Incompatible_with_cycle_network">Incompatible
with cycle_network</span></h2>
<p>This tag is incompatible with the predominant usage of <tt
dir="ltr" class="mw-content-ltr"
style="background:#EEF;font-size:1em;line-height:1.6"><bdi
style="white-space:nowrap"><a
href="https://wiki.openstreetmap.org/wiki/Key:cycle_network"
title="Key:cycle network">cycle_network</a></bdi>=*</tt>.
This key was originally intended to identify a specific network
with uniform signage – a renderer was supposed to be able to
choose a shield based on a combination of <tt dir="ltr"
class="mw-content-ltr"
style="background:#EEF;font-size:1em;line-height:1.6"><bdi
style="white-space:nowrap"><a
href="https://wiki.openstreetmap.org/wiki/Key:cycle_network"
title="Key:cycle network">cycle_network</a></bdi>=*</tt> and
<tt dir="ltr" class="mw-content-ltr"
style="background:#EEF;font-size:1em;line-height:1.6"><bdi
style="white-space:nowrap"><a
href="https://wiki.openstreetmap.org/wiki/Key:ref"
title="Key:ref">ref</a></bdi>=*</tt>. But it appears that
cycle highways are signposted and numbered differently in each
country, so there's no such cycle network as "cycle highway":

<p>A renderer would have to perform a spatial query to reliably
display the correct shield for each of these routes, somewhat
undermining the push to have renderers use route relations instead
of <tt dir="ltr" class="mw-content-ltr"
style="background:#EEF;font-size:1em;line-height:1.6"><bdi
style="white-space:nowrap"><a
href="https://wiki.openstreetmap.org/wiki/Key:ref"
title="Key:ref">ref</a></bdi>=*</tt> tags on ways.
</p>
<p>We already made this mistake once by repurposing the <tt
dir="ltr" class="mw-content-ltr"
style="background:#EEF;font-size:1em;line-height:1.6"><bdi
style="white-space:nowrap"><a
href="https://wiki.openstreetmap.org/wiki/Key:network"
title="Key:network">network</a></bdi>=<bdi>lcn/rcn/ncn</bdi></tt>
tags for routes outside the United Kingdom, leading to the
otherwise redundant key <tt dir="ltr" class="mw-content-ltr"
style="background:#EEF;font-size:1em;line-height:1.6"><bdi
style="white-space:nowrap"><a
href="https://wiki.openstreetmap.org/wiki/Key:cycle_network"
title="Key:cycle network">cycle_network</a></bdi>=*</tt> as
a workaround. Let's avoid making this mistake again by deprecating
<tt dir="ltr" class="mw-content-ltr"
style="background:#EEF;font-size:1em;line-height:1.6"><bdi
style="white-space:nowrap"><a
href="https://wiki.openstreetmap.org/wiki/Key:cycle_network"
title="Key:cycle network">cycle_network</a></bdi>=<a
href="https://wiki.openstreetmap.org/wiki/Tag:cycle_network%3Dcycle_highway"
title="Tag:cycle network=cycle highway"><bdi>cycle_highway</bdi></a></tt>
in favor of country-prefixed values like <tt dir="ltr"
class="mw-content-ltr"
style="background:#EEF;font-size:1em;line-height:1.6"><bdi
style="white-space:nowrap"><a
href="https://wiki.openstreetmap.org/wiki/Key:cycle_network"
title="Key:cycle network">cycle_network</a></bdi>=<a
href="https://wiki.openstreetmap.org/w/index.php?title=Tag:cycle_network%3DNL:cycle_highway&action=edit&redlink=1"
class="new" title="Tag:cycle network=NL:cycle highway (page
does not exist)"><bdi>NL:cycle_highway</bdi></a></tt>, or by
choosing a different key altogether like <tt dir="ltr"
class="mw-content-ltr"
style="background:#EEF;font-size:1em;line-height:1.6"><bdi
style="white-space:nowrap"><a
href="https://wiki.openstreetmap.org/w/index.php?title=Key:cycle_highway&action=edit&redlink=1"
class="new" title="Key:cycle highway (page does not exist)">cycle_highway</a></bdi>=<bdi>yes</bdi></tt>.
