<p>Hi</p>
<p>I am not at all clear from this as to how to tag a natural gas
pipeline and the various equipments at substations, or water or
liquid hydrocarbons eg aviation fuel.</p>
<p>Is a product tag needed? The assumption is electricity (IEC 601
is purely electricity) but what about other stuff especially
where words and phrases are common irrespective of product.</p>
<p>Regards</p>
<p>Tony<br>

<div>Hi,</div>
<div><br>
</div>
<div>I recently found out that current tagging for
substations (power or pipelines) with substation=* key
actually merge two distinct concepts.</div>
<div>It deals with hierarchy levels and specific network
functions a substation can host.</div>
<div>It's hardly possible to document the substation=* key
properly with the values voted in the last pipeline
extension proposal.</div>
<div>Main issue is a "compression substation" can also be
a transmission or distribution substation and it hasn't
been solved during the review process.<br>
</div>
<div><br>
</div>
<div>I wrote a new proposal to move the less used values
of substation=* in more detailed and dedicated functions
subkeys.</div>
<div>It also adds substation=generation (formerly
substation=transmission) and substation=delivery which
are missing currently.<br>
</div>
<div><a href="https://wiki.openstreetmap.org/wiki/Proposed_features/Substation_functions" target="_blank">https://wiki.openstreetmap.org/wiki/Proposed_features/Substation_functions</a></div>
<div><br>
</div>
<div>This not-so-big change on < 2000 existing objects
(out of +300k power substations and 7k pipeline
substations) would enable OSM to have a better matching
with IEC definitions and a more usable tagging. We will
be able to tag more objects with substation tagging
(delivery substation mainly) than before.<br>
</div>
<div>Most of function subkeys has defaults that allow us
to add them on specific situations if required only.<br>
</div>
<div><br>
</div>
<div>I'll add more example before vote start (surely next
Febuary or March depending on how RFC goes)</div>
<div><br>

<div>All the best</div>
