<p>Hi <br>
</p>
<p>I agree with you. Tagging something like this is difficult. The
tagging depends on the reason for tagging, the Leeds &
Liverpool canal is a relation which contains the water ways of
this feature, if the staircase locks are being tagged because of
their tourism features then a relation containing all of the
tourism objects is appropriate and tagged with appropriate
heritage and tourism tags - I think at the relation level as the
objects all combine to make the feature.</p>

<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>

<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 ...

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>
