<p>If using the ExtendedMeasurementsOrFacts, as Andrea recommends, I should include the occurrence ID from table occurrences in the column `occurrenceID`.<o:p></o:p></p>

</span></span></span><![endif]><span style="font-size:10.5pt;font-family:"Calibri",sans-serif;color:#1F497D">In this case, I would say yes. In general, that would depend on whether the measurement or fact relates to the event, or to the occurrence. The specification
says about occurrenceID: "</span>The identifier of the occurrence the measurement or fact refers to. If not applicable, it should be left empty.".
<span style="font-size:10.5pt;font-family:"Calibri",sans-serif;color:#1F497D">This refers back to the introductory paragraph (see https://tools.gbif.org/dwca-validator/extension.do?id=http://rs.iobis.org/obis/terms/ExtendedMeasurementOrFact), stating that "</span>
When used with Event Core it allows to create an additional link between the eMoF and the occurrence extension."
<span style="font-size:10.5pt;font-family:"Calibri",sans-serif;color:#1F497D">In the case of measures of coverage, it would indeed be occurrence related</span>.<span style="font-size:10.5pt;font-family:"Calibri",sans-serif;color:#1F497D"><o:p></o:p></span></p>
<p style="margin-left:.5in"><span style="font-size:10.5pt;font-family:"Calibri",sans-serif;color:#1F497D">However, please be aware that this is a contruct that no longer falls withing the "start schema" setup that an IPT supports (and GBIF indexes from): links
can only go one level deep from the center, and links between satelite tables (in this case occurrence and eMoF) are not supported. That said, it is a good format for a dataset to exist in though, regardless of GBIF, at indexing, losing some of that information.<o:p></o:p></span></p>
<p style="margin-left:.5in"><span style="font-size:10.5pt;font-family:"Calibri",sans-serif;color:#1F497D">Alternatively, you could consider using the combination of

<a href="https://dwc.tdwg.org/terms/#dwc:organismQuantityType">https://dwc.tdwg.org/terms/#dwc:organismQuantityType</a> on occurrence records directly for the measure that this fits best, and only use the extension for the other one.

though these are now so generic that I am not sure how useful they would be for your case.<o:p></o:p></span></p>

<p>Hi all,<o:p></o:p></p>
<p>Thanks, Andrea and André :-) for your replies.<o:p></o:p></p>
<p>Just to be clear, this is how I should do:<o:p></o:p></p>
<p>In the event core, I leave `samplingProtocol` blank, because each event will have two sampling methods. The sampling method should be included in `measurementType`of the (Extended)MeasurementsOrFacts DwC Extension.<o:p></o:p></p>
<p>I am curious what will happen when GBIF ingests the data. Will any of the sampling methods be associated with the occurrences?<o:p></o:p></p>
<p>Cheers,<o:p></o:p></p>

<p class="MsoNormal">Dear all,<br>
<br>
One of our publishers is preparing an event based dataset with plant <br>
surveys, where two measurements were taken at each location: a Braun <br>
Blanquet Scale value and % of coverage.<br>
<br>
The normal option to create this dataset would be to make two event <br>
records for each plot, one for each survey method. This allows to <br>
preserve all original data, but will result in two occurrences for the <br>
same species at the same plot.<br>
<br>
The other option would be to report only one of the survey methods, <br>
avoiding occurrence duplication, but not preserving data for the other <br>
method.<br>
<br>
Would anyone have a suggestion how to prepare the dataset, so that it <br>
keeps values for both methods and does not create duplication of <br>
occurrences?<br>
<br>
Or the duplication is not an issue, and we should publish data for both <br>
methods?<br>
<br>
Thanks,<br>
<br>
Rui<br>
