</div>Dear John,<br>
<br>
You underestimate the intelligence of OSM contributors and their<br>
motivation to make the map better. Particularly you underestimate<br>
their wish for better highway shields. You think increasingly<br>
specific network tags are too complicated for OSM contributors? Are<br>
you familiar with the great success of the Karlsruhe addressing<br>
Schema?[1] ;-)<br>
<br>
They will tag it. Absolutely they will tag it. When Mapnik support<br>
for local shields is adopted on <a href="http://osm.org" target="_blank">osm.org</a> and announced on talk-US it<br>
will take less than 7 days for the US Interstate system to have shiny<br>
new shields from coast to coast. I'll send you a bottle of Canadian<br>
Maple Syrup if I am wrong.<br></blockquote><div><br>after more than a year after tiger import still most US highways are untouched. have no or wrong ref values. broken connections .... the list is endless<br>nothing will happen in 7 days. <br>

</div>"S" and "I" are so lacking context as to approach line-noise.<br>
"us_ny_ny_co" even hints at the right answer, without reading the<br>
docs.<br>
<div class="im"><br></div></blockquote><div><br>you shouldn't use well established tags in the wrong way. us_ny_ny_co is not a network name. the network is I, US, ....<br> network is useful for routing applications too and should be used as signed in reality.<br>
If we need a tag for mapnik rendering call it mapnik:<something> or shildsymbolizersomething ....<br><br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

</div>Those are mandatory with your incomplete tags. They are optional with<br>
explicit, human-readable tags.<br>

<br>
</div>I agree that failover to the UK style shield is better than nothing.<br>
