Hello @tdwg/cd

GOAL: to create an agreed format, before analyzing use-cases, in order to support CD data model development and testing. Once we agree on the format, we will begin breaking down the use cases. Thanks for your review.

• Please review this use-case breakdown method (as soon as possible - say by May 3rd)
• Note any criteria missing that you will need for developing/testing the data model.
• Please add missing criteria, or comments on the method, as comments to this issue. Thanks.

This method was used by Olaf Banki at a recent ICEDIG Meeting to develop a vision for a collections digitization dashboard (CDD) model for SYNTHESYS+ to use to build a CDD for DiSSCo.

Note, for example, we decided we should add a dimensions column

• dimensions column added (where we say what dimensions this use case requires). See what we mean by dimensions in the V 1.0 CD data model
• for each use case, we will look at the data elements to figure out what dimensions must be in place to support these data types. We will note any elements that don't fit into any of the current dimensions.
• metrics may be a missing dimension that we need to add to the model

For your reference, here is a much more complicated use case breakdown model from RDA. It incorporates many more levels of information (e.g. "concepts of operations" - or imagining the requirements dictated by the data, say, for how to move the data around, or keep it up-to-date, or how to share it).

Scope: note too that scope for CD is at the collections-level (not individual specimens). So only use cases in the ICEDIG example relevant to collections are pertinent to consider for this effort.

Perhaps we need to

• Change the information on this page https://github.com/tdwg/cd/tree/master/reference/crosswalks to reflect the Use Cases are now for CD (from NCD).
• Do we need a note (or in a README.md) that shares the NCD crosswalks are still relevant?

Add to repo as markdown files rather than wiki pages

Please provide link to the BioCASE project website and an expansion and/or link to RLG Programs and link to RAVNS.

I want to use github to submit a new use case.

• Get ICEDIG (Niels Raes) to add use cases (or link to the Use Cases List created for planning recommendations to SYNTHESYS+ for building the Collections Digitization Dashboard for DiSSCo.
• Add them, or a link to them, here https://github.com/tdwg/cd/tree/master/reference/use_cases

https://www.tdwg.org/community/cd/

Includes reflecting changes to:

• the physical collections over time e.g. disposals, accessions, acqusitions, collection moves
• how the data represent the physical collections e.g. adding dimensions, splitting / lumping CDs

Persistent identifiers (PIDs) will be an important feature of any registry of collections and collection-holding institutions. If the CD metadata standard for descriptions of collections applies to the exchange of information between collection registries, a single PID system, or a well-defined coordination of multiple PID systems, will be essential. We should develop a plan that will enable us to recommend the adoption and deployment of one or more PID systems as part of CD.

This class has not yet any properties and need to be elaborated more

What to do about updating this entry https://fairsharing.org/bsg-s000202/ about NCD?

1. do we link to it somewhere (old, but relevant links)
2. update the information there to indicate cd std is in development?

Covering the repo structure and conventions, and project management setup

Though David Shorthouse proposed it as a new term for Darwin Core, the idea might have merit at the data set level. See tdwg/dwc#180.

We need to identify the dimensions, before in each case considering what is required to incorporate them into the model / standard. The majority will already be described by existing standards (although potentially multiple options), so will be a case of hooking into the model rather than designing from scratch.

I want to collect specimens in another country. I do not know the regulations regarding scientific collection and export of material in that country and I want advice and help. I want to find people in a local herbarium who will know what regulations exist and can give me advise.
I might also look for a herbarium in that country to deposit duplicate specimens. This can be to conform to regulations, as a courtesy or just as a safety measure.

Potential stakeholders include funding agencies (like conservation companies, and foundations) who are looking for certain data that are needed for addressing their missions. This metadata has the potential to expose what's available and help with prioritizing funding.

Article 40.7 of the International Code of Nomenclature for algae, fungi, and plants specifically mentions Index Herbariorum as the source of abbreviations to identify collections were types are deposited.

From 1 January 1990 all types for a new name must state where the type is deposited

ICN Article 40

40.7. For the name of a new species or infraspecific taxon published on or after 1 January 1990 of which the type is a specimen or unpublished illustration, the single herbarium, collection, or institution in which the type is conserved must be specified (see also Rec. 40A.5 and 40A.6).

Note 4. Specification of the herbarium, collection, or institution may be made in an abbreviated form, e.g. as given in Index Herbariorum (http://sweetgum.nybg.org/science/ih/) or in the World directory of collections of cultures of microorganisms.

This is done. Contributors: @debpaul @mswoodburn @WUlate
