<p>I haven't forgotten this - work and some thought have intervened.</p>
<p>The agreed basis is <br>
</p>
<p>heritage:operator=Historic England<br>
heritage:operator=Cadw<br>
heritage:operator=Historic Environment Scotland<br>
heritage:operator=Northern Ireland Environment Agency</p>
<p>ref:GB:he=12345<br>
ref:GB:hs=LB2345<br>
ref:GB:cadw=34567<br>
ref:GB:niea=55643</p>
<p>this also works for non statutory organisations eg CAMRA</p>
<p>heritage:operator=CAMRA</p>
<p>ref:GB:CAMRA=xyz<br>
</p>
<p>I think that in the case where an object is in two or more lists
e.g. Chirk Aqueduct then relations needs to be used, my concept is</p>
<p>object Z - tagged with physical properties, it is then a member
in two relations, a relation A holding Historic England refs and a
relation B holding Cadw refs. This relation method also works for
example a pub in CAMRA and Historic England</p>
<p>I'll start making the wiki changes in the next day or so if there
are no objections.<br>

<div>Late to this as ever. I think Robert summarised all the
important things I wanted to say, so just a few additions:</div>
<div><br>
</div>
<div>* Use cases: I imagine the primary use cases will be
related to individual lists, so ensuring that they are readily
discoverable at the list level helps.</div>
<div>* Using an Operator tag as effectively part of the primary
key has problems in that it's easy to make typos or to forget
what the canonical form of the operator name is in osm (check
out Weatherspoons, for instance).</div>
<div>* Other heritage lists. There are a considerable number of
perfectly valuable non-statutory heritage lists. Off the top
of my head those of Camra (Heritage Pubs), 20th Century
Society (active in achieving the recent listing of Dunelm
House), local civic societies, <a
href="http://www.rhrp.org.uk/surveystatus.htm"
moz-do-not-send="true">railway heritage groups</a>, and
local authorities (which may retain lists which will be
considered for planning purposes).</div>
<div>* List ownership changes, as mentioned. The earliest
mention of UK listed status I'm familiar with is in volumes of
the Pevsner series abbreviated as MHLG, and even in the
history of OSM we've seen English Heritage transform to
Heritage England, and similar changes in many natural heritage
bodies.</div>
<div><br>
</div>
<div>I think including a country code in the key is probably
useful to provide context & avoid potential collisions in
use of initials.</div>

<br>
There certainly are cross-border structures that are listed by
more than <br>
one heritage authority. Chirk aqueduct and Chirk viaduct, for
example, <br>
are both listed by both Historic England and Cadw.<br>
