<p>Jonathan,</p>
<p>That sounds similar to our approach. <br>
</p>
<p>Generally speaking there is a "best source" for data - the place
where updated data is reliably available - and in the case of USGS
that is their web site, so we just point people there. For LTER
data, of course, we are the "best source" so we document that data
and share it via PASTA, DataONE etc. <br>
</p>
<p>There are a few cases where we do maintain "local" copies of
external data, either because the availability at the source is
unreliable (not the case for USGS), the data volume is best dealt
with on a local network (e.g., large LiDAR datasets), the data is
really hard to locate and extract, or where there is a reason that
you want to maintain a particular static version of the data
(e.g., for a series of analyses conducted over a period of time
where you don't want the underlying data to change). However, we
DON'T include them in the data catalog. <br>
</p>
<p>Don't forget that for your derived products you can include
references to the USGS source in a "methodStep" in EML. For
referring to source data already documented in EML and stored in
PASTA via the "provenance" web service (e.g.,
<a class="m_-4550727407362179302moz-txt-link-freetext" href="https://pasta.lternet.edu/package/provenance/eml/knb-lter-bes/332/580" target="_blank">https://pasta.lternet.edu/<wbr>package/provenance/eml/knb-<wbr>lter-bes/332/580</a>)
which will produce a methodStep "stub" that can easily be included
in your metadata. For USGS you'll need to generate your own
methodStep - but you can use the example produced by the
provenance web service to do that....</p>
<p>Hope that helps!</p>

<div dir="ltr">Hi IMs!
<div><br>
</div>
<div>I have a question on how to best represent data that your
study uses, but is provided by others. If you use such data,
we could use your insights on how you make that portion of
your data available to the community and the LTER.</div>
<div><br>
</div>
<div>Baltimore Ecosystem Study gets its stream flow data from
the USGS. We in turn use this flow data to calculate our
daily loads and other results that we track. The USGS data
are kept on their website and we incorporate them into our
work.</div>
<div><br>
</div>
<div>For the purposes of making our data available to the larger
community, (LTER, PASTA, DataONE, etc.) we have historically
just pointed to the USGS data on the USGS site. (example: <a href="https://waterdata.usgs.gov/usa/nwis/uv?01589197" target="_blank">https://waterdata.usgs.gov/<wbr>usa/nwis/uv?01589197</a> )
as opposed to collecting our own copy and providing it
ourselves.</div>
<div><br>
</div>
<div>The above precludes us from providing a direct link to the
data such as that that would be PASTA "type 1".</div>
<div><br>
</div>
<div>If you have any suggestions as to how, if differently, we
should represent these data, which are integral to our work,
but not provided by us, I would very much appreciate hearing
them.</div>
<div><br>
</div>
<div>Thank you!</div>
