Add categories (goals) to SDG targets

[andylolz]

There’s a link between these two codelists, which it’s useful to be able to see on the reference site and elsewhere. The DAC (replicated) codelist includes this link as category elements.

This looks like a step forwards to me, only not approving because I don't have my head around what is possible to do with codelists in terms of what their structure enables, so can't tell if this is 'schema correct' or whatever the appropriate phrase it (or if we want to stick to that)

Cool – thanks for taking a look Matt!

So I sent the equivalent PR upstream here: IATI#304.

So for the IATI reference site, it adds references from SDG targets to their respective SDG goals:
http://sdg-categories-iati-codelists-nonembedded-refbot.surge.sh/codelists/UNSDG-Targets/#codes

On https://codelists.codeforiati.org, this would add a reference in the description, and categories, similar to those shown on the Sector codelist.

Thanks - good to see that it is used elsewhere (Sectors).....part of me feels that this hints about how the SDG Indicators (the third level, non-replicated to date) codelist should be setup.

[andylolz]

Yep, agreed. It’s unclear why this wouldn’t also be replicated.

Looks great!!

Ace – so the categories are now shown here:
https://codelists.codeforiati.org/UNSDG-Targets/

Thanks for reviewing and merging, both!
