Add material core to sandbox

[timrobertson100]

In the SPNCH workshop we will have a hands-on exercise to map data. One track of that will be mapping Material to Darwin Core Archives in the Sandbox (another to a Frictionless model which is yet to be defined).

To bring DwC-A closer to the work on the model, we'd like to introduce a Material core to use instead of Occurrence which is a layer of confusion. This resurrects and will replace previous ideas with the MaterialSample core which never made it to production.

This will be largely similar to Occurrence core, but removing those fields NOT specific to Material.

@tucotuco - can you please confirm Material and materialID as the preference over the MaterialSample terminology current in DwC, knowing it will align better with the forthcoming model?

[tucotuco]

Confirmed to use Material and materialID for this.

Clarification, do you mean, "This will be largely similar to Occurrence core, but removing those fields NOT specific to Material"?

[timrobertson100]

Thanks - corrected

Notice that MaterialEntity and materialEntityID are close to be proposed

[tucotuco]

@timrobertson100 We may save ourselves some hassle by going with MaterialEntity and aligning with the Task Group proposal. There were arguments against Material as being both a noun and an adjective and therefore potentially confusing or misleading.

Available in the sandbox and the issue linked above captures the need for IPT v3 support
