I don't think necessarily this is the right place for it, but this prompted me to wonder - is there any scope for making recommendations in terms of current data practices that might be adopted to better enable move to LD for libraries?

This is something we've been discussing with cataloguers following our work in the Lucero project and based on our experience of trying to convert MARC to LD
- thinking of things like... In MARC21:

Use X00 $$4 and X10 $$4 to indicate relationship between person and item catalogued
Include Authority identifier $$0 in all applicable fields - e.g. 100; 650 etc. etc. (to enable linking to authority sources such as VIAF)
Ensure accurate use of fixed length fields (LDR, 006, 007, 008 etc.)

There are quite a few places in MARC where identifiers or encoded values can be recorded, which would map to existing LD URIs - the more these are filled out, the easier a useful transformation to LD might be

Any support for this idea? Or is it out of scope/too late?

The mental block that needs to be overcome is knowing the hubs probably don’t contain every instance needed, but developers shouldn’t let that be a show-stopper.

One of the nice things about OWL, though, is that domain-specific terms can also be mapped to other terms without community involvement. I think this is a useful point because many developers still seem to believe that existing vocabularies are all-or-nothing. [I see this is mentioned in the “Directly use, or map to,…” section.]
