This workshop focus on building skills of staff whose job it is to maintain and update datasets in existing IPT instances. From the research community, we invite taxonomists who wish to learn how to share and publish their occurrence data in the arwin Core Archive (DwC-A) format. This workshop will focus on occurrence data, with the intent to discuss use of IPT extensions (e.g., media, genomics, determinations, and relationship extensions). There will be a sample dataset for teaching. Participants are strongly encouraged to bring their own dataset to work with. A summary of the workshop outcomes is available at its wiki page.
