Hi, Frederik:
I was searching for ref:pht in the tagging plan of the wiki and I can't
see no reference to that anywhere.
In point 4) of "Main steps" of the workflow, OSM users are asked for:
"Examine each way in the ToDo list,
Locate the reference of the stream for this way in the location map.
Search using the reference the stream in the list cauces.csv.
Add the tags indicated in #Tagging Plans."
So they will have to use the ref:pht to find the name, but they aren't
asked to add the ref:pht to the tags, only the tags present in the
tagging schema of the wiki: name=*, alt_name=*, waterway=* and
intermittent=* (plus the changeset tags).
Cheers,
Rafael.

Two things stick out for me:
1. You propose to map all streams with "intermittent=yes". I am not
familiar with Tenerify hydrography but is it really correct that they
are all subject to drying out?
2. You propose to import the original object ID as "ref:pht". At the
same time you say you're not envisaging any later updates. Keeping an
external ID can often be an impediment for mappers working with the data
later: Imagine you want to merge two streams and your editor asks you:
"should the resulting stream have ref:pht=123 or ref:pht=234"? That
would certainly confuse you. Or if you split a stream and you wonder if
it is ok that you are now breaking the presumed 1:1 relationship to the
original data. -- I would recommend to include ref:pht only if the
assumed good use of that is much bigger than the potential issues. You
write that the ref:pht could "be used to locate the stream in the
location map", but when the stream is mapped in OSM then it should be
easy to locate it on any map!
Bye
Frederik
