Thanks @pelleaardema and just to clarify that the intention on closing the previous post was only in order to consolidate all the posts relating to any candidate changes to the handling of the SDGs via the Standard.
However, in addition to the previously referenced Std Upgrade post of Recognising SDGs as Policy Markers my colleague @petyakangalova who is assisting with the coordination of the Standard Upgrade process (thanks Petya) also reminded me of an alternative post for 'Results - add more indicator vocabularies' which as you will see also includes the proposal for adding an entry for the SDG indicators.
As it is still possible to post to the Standard Upgrade related posts (even if a proposal has been rejected) I would like to link these posts perhaps with the recommendation that the URL link that you have provided for the SDG indicator vocabularies may be a better link to use? Would that be okay?
