Remove undefined terms in parameterGroup examples

[chris-little]

Removed undefined terms narrowerThan, statisticalMeasure and statisticalPeriod from the Parameter Group examples. Add another example to the JSON-LD section.

Hi @chris-little, thanks for doing this. Having thought about it, I'm wondering if we should just remove the section about statistical measures altogether for now. There's a lot of stuff that would need defining, even in the new simplified version. How about simply including some placeholder text, e.g. "ParameterGroups can also be used to gather related statistical quantities, but this will be defined in a future version of the spec"?

This looks OK as far as I can tell but would benefit from a review from someone who's more familiar with how to insert new vocabularies via the JSON-LD context - perhaps @KathiSchleidt?

I'm fine with the hack of referencing eurostat glossary terms, but don't understand why you removed the statisticalPeriod, this loses the daily aspect, now only available in prose.

[KathiSchleidt]

On narrowerThan, either drop or provide correctly! I'd remove in the first JSON examples, only provide in the last one where you have "narrower": ["http://vocab.nerc.ac.uk/standard_name/sea_surface_temperature/"]

"narrower": "http://www.w3.org/2004/02/skos/core" makes absolutely no sense!!!

I left various comments in the file

The PR was to remove undefined terms in response to your Issue #194 . It is only an example. It is not normative. Do you have a reliable source definition of statisticalPeriod?

@jonblower @letmaik This is a tidy up of examples so that they work, and point to resolvable meaningful resources. And fix my mental glitch.

[chris-little]

@jonblower Have you time for a review? @KathiSchleidt has corrected the JSON-LD syntax. Parameter Group examples simplified and fully resolvable.

[jonblower]

@chris-little just wanted to draw attention to my review comment. Do we need the extra example (lines 978 and onwards?) This seems to mainly be a copy of the same example from earlier in the spec.

(Also it would be good to tidy up the formatting/indentation.)

@ghobona @gbuehler Have we just found a Metanorma bug? I have no idea what Lutaml is (Look Up Table AsciiDoc Markup Language?)
@jonblower FYI

[gbuehler]

@chris-little The standard / document.adoc builds fine for me. What specifically are you seeing? As for LutaML, see: https://www.metanorma.org/author/topics/automation/lutaml_uml/
