Indicators: Series Identification

[lomky]

Followup to question raised on #12 about Indicator series identification.

• PROPOSAL: We should create a semantic relationship between the related indicators.
  • NEEDED: Semantic relationship to use. @amruelama to research.
  • NEEDED: Semantic relationship added. @lomky to implement.
  • NEEDED: Update current Indicators
  • OPTIONAL: extend this to other Reports (NCA3->NCA4? etc).

[lomky]

We considered using "WasDerivedFrom" at the Indicator->Indicator level, but are coming around to the idea of adding the new verb "dct:replaces" / "dct:issReplacedBy".

We would support this explicitly on USGCRP Publications (Indicators, NCA) and prominent entities in GCIS (IPCC, often cited Datasets, NCA Regions) as needed, but not proactively.

[lomky]

We few this as a connection at the top-level only. Indicator->Indicator, NCA3->NCA4. Not their all their sub components.

This should not be used on annual reports about events in any given year (i.e. extreme events of 2015, extreme events of 2016)

[lomky]

It may be worth explicitly tagging the latest version of a thing. Probably not semanticly.

Work to do:

• Kat:
  • Add the terms dct:replaces dct:isReplacedBy
• Amrutha:
  • Add the connections on the Indicators
  • Add the connections on the NCA

@amruelama dct:Replaces exists now. You can move forward connecting Indicators and NCA reports as discussed.

@lomky In what specific cases have we planned to use dct:isReplacedBy? Right now, I see when Report B 'replaces' Report A, in both report pages, it shows 'Report B' replaces 'Report A' or 1 report replaces this report (Report A), instead of using 'dct:isReplacedBy'. Is it possible to automatically use 'dct:isReplacedBy' term in Report A instead of 'replaces'?

[lomky]

@amruelama nope, looks like they're not actually linked in our system setup :(

here's the existing ones break down:

 cito:cites          |   138
 cito:isCitedBy      |   161
 prov:wasDerivedFrom |  1802
 prov:wasInformedBy  |    10

So we use them pretty equally for the cites & cited by. for the others we prefer the equivalent to isReplacedBy. I think we can just pick a preferred convention?
