<div dir="ltr">Another thought on this. The site relation requires a main tag. That's fine for the piers with historic=heritage. It might also be alright for a lock flight where combined with place=locality if that's an appropriate tag, although you might argue it is an extant feature. The site page also points out there are many cases where the main tag is site=* and that is undocumented, although having browsed the first few pages on taginfo many seem like they could just be replaced with a documented tag. So, site=lock_flight would be an alternative possibility but perhaps not very desirable either.<br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, 15 Aug 2021 at 12:23, Tom Crocker <<a href="mailto:tomcrockermail@gmail.com">tomcrockermail@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto">Hi Tony<div dir="auto"><br></div><div dir="auto">I think you're right; that's a good relation to use for both those situations.

<p>Hi,</p>
<p>I've been having similar thoughts for listed buildings of
Historic England et al particularly gate piers. I looked at type =
site and type=group and decided to use type = site as site is in
the wiki and has 158K uses, group is not in the wiki and has 250
uses.</p>
<p>But I might just be following all the other sheep ... . .. . <br>

My main motivation is how to highlight subjectively "interesting"
features for tourism and education purposes with quantitative
tagging. It is now possible to find the general location as a
tourism=attraction and pull up full information about it,
including all the locks. This is where I am going with a personal
Android app.<br>
<br>
Being more serious about relations than my first thread comment, I
loathe the over-use and often unnecessarily complex use of
relations where a simpler solution will suffice. That said, it
took a two cups of coffee research and thought but I think the not
well-liked 'group' relation does seem ideal here IF you want more
detail rather than just Where Is It?<br>
<br>
For Foxton Lock, I've followed Dave F's suggestion and simply
added more detail to the existing place=locality tag. So, you can
find it and know what it is using free-form text, but doesn't say
anything quantitative about the locks themselves - perhaps that
just doesn't matter?<br>

Foxton Locks<br>

I noticed that one can't find the Fort Augustus Flight at all in
OSM, so I have tried a half-way approach and created a
place=locality tag but put it on a group relation:<br>

"<span>The largest narrow boat staircase is the
Watford locks which has four steps and is located on the
Leicester line of the Grand Union Canal.<br>
On the Droitwich Junction Canal we have a two staircase lock -
locks 4 & 5. The next nearest Staircase lock are the
Stourport locks on the Staffordshire and Worcestershire Canal"</span><br>

I remember going there with the school. From memory the
