<p>Hi Markus,</p>
<p>Thank you for your quick reply.</p>
<p>I understand the need to make the updated extension "correct",
accordingly to the "class".</p>
<p>However, the lack of implementation on GBIF in ingesting related
resources is a point of concern.<br>
</p>
<p>It brings to my memory the XVII Congress of the European
Mycological Association (EMA), in 2015, in Madeira. In that
congress, Dmitry Schigel and myself, we were invited to organise a
symposium on Biodiversity Informatics and Fungal Data, in the end
of the first day. But, in the opening plenary session of the the
conference, the President of EMA, David Minter, stated with
emphasis that GBIF deliberately lacked support to all mycological
researcher community. His main argument was that GBIF does not
support interactions between species, which is critical data for
many fungi species. Unfortunately, I think we have to agree with
him!<br>
</p>
<p>Using associatedTaxa is a limited solution if we want to document
the occurrence of the interaction. And using the extension will
create problems when documenting interactions between different
biological groups, namely in the metadata description.</p>
<p>I came across this problem precisely because I am preparing and
update of a dataset of fungi
<a class="moz-txt-link-freetext" href="https://www.gbif.org/dataset/651c0bec-bd78-4300-bbb0-5ed172fc82af">https://www.gbif.org/dataset/651c0bec-bd78-4300-bbb0-5ed172fc82af</a>,
where all fungi are associated with a plant host. The use of the
extension would allow us to define, for example, the establishment
means of the host. But, if GBIF is not ingesting the resource
relationship, we are only left with the option of using
associatedTaxa and occurrenceRemarks to document interactions,
which is not my preferred option.</p>
<p>Best regards,</p>
<p>Rui<br>

Hi Rui,
<div class=""><br class="">

<div class="">the scientificName term was dropped because it is
not part of the regular DwC relation "class":</div>

<div class="">The resource relation can relate any kind of things
and GBIF needs to lookup the ids to find the scientificName of
the related resource in your case. Unfortunately this is not
implemented right now, so by upgrading to the latest "correct"
version of the extension you will lose the related scientific
name on the GBIF occurrence page. </div>

<div class="">Hi IPT list members,<br class="">
<br class="">
Could anyone help me to understand what are the
implications of doing an update of the Darwin Core
Resource Relationship extension, that our IPT
installation is asking to update?<br class="">
<br class="">
I am particularly concerned with the dataset <a
href="http://ipt.gbif.pt/ipt/resource?r=edp_tua_arthropoda_eia"
class="" moz-do-not-send="true">
http://ipt.gbif.pt/ipt/resource?r=edp_tua_arthropoda_eia</a>, that is
using this extension. The table resourcerelationship.txt
in the dataset uses the term scientificName to identify
the name of the tree where larva of butterflies feed on.
This is reflected in the occurrence data at <a
href="http://gbif.org" class="" moz-do-not-send="true">gbif.org</a>,
for example, in this record:
<a href="https://www.gbif.org/occurrence/1585354292"
class="" moz-do-not-send="true">https://www.gbif.org/occurrence/1585354292</a>.<br
class="">
<br class="">
I noticed that the update of the extension dropped the
term scientificName. So, could anyone guide me on the
changes that I need to do in the dataset, in order to be
able to update the extension and have the same or
equivalent information about the relationship in the
record at <a
href="https://www.gbif.org/occurrence/1585354292?"
