Date, Prep, Webinar on Extensions - for 2018

[debpaul]

We need a webinar on extensions in general. Many tickets reference issues with understanding how to use them, where to find examples of them in use, and how to develop new ones. A related topic that will come up then, is how the "core" file inside the DwC-A can be different. So the webinar will certainly need to review the DwC-A. Concrete examples needed - that we can link to in documentation.

@pzermoglio suggests we also use this opportunity to cover work-a-rounds for sharing "many-to-many" relationships using DwC Archives; perhaps ask Dave Watts dave.watts@csiro.au to share example and possibly cover the topic.

This webinar would help address questions in the following tickets:
tdwg/dwc-qa#9
tdwg/dwc-qa#18
tdwg/dwc-qa#22
tdwg/dwc-qa#76
tdwg/dwc-qa#79

maybe partially answer or address bits of:
tdwg/dwc-qa#21
tdwg/dwc-qa#28

example of extension issues in development
tdwg/dwc-qa#74

Review whether this is still necessary, given the Extensions mini-hour given at TDWG 2017.

@tucotuco I believe we need one - a webinar on extensions that is. Especially one where we can point to examples of particular extensions in use. As part of a greater strategy - we need to share Paula's mini-hour widely via SPNHC for example. The TDWG audience (most anyway) likely get extensions. The SPNHC audience hasn't really seen this yet. It's one of the reasons I suggested we figure out how to do something at the SPNHC-TDWG meeting in 2018 - focusing on SPNHC audience.

I believe that a large part of confusion around extensions is because the data-package format DwCArchive use the name Darwin Core... The zippd DwCArchive files (for the GBIF IPT) would much more appropriately be named Biodiversity Data Archive (BDA) - or similar. People tend to mix up Darwin Core-extensions and DwCArchive-extensions.

One the second topic: I love the idea of getting support for a many-to-many relationship into the DwCArchive ("BDA") format - or rather to be specific - between DwCArchive files - using persistent identifiers in a community-wide agreed, specified and well documented way.

@dagendresen About the many-to-many relationships, it would be great to have someone (Tim Robertson) talk about the W3C "CSV on the Web" standard (https://www.w3.org/standards/techs/csv#w3c_all), for which there is a Darwin Core Archive use case:

@timrobertson100 we'd like to invite you to talk about the W3C efforts to make CSV a standard recognized data type. Are you up for this? Please?
