Agree

But... is my request not clear?

I understand the owl:sameAs mechanism STATES the equivalence of thingies.

That's after the fact.

What—if anything—in SW helps DISCOVER the relationships?  It's not much value if one cannot trace the STATEMENT back to the DISCOVERY process.

No, you would transform the legacy data (using transient or materialized views) and then apply the reasoning at the view layer.

Strong disagreement.

Removing the data from the legacy systems messes with the semantics of the production data.  There are all sorts of invisible, screwy "rules" buried inside legacy systems

cannot do is "rip and replace"

Are there factions in SW who believe they can "rip & replace?"  Amazing.

The track record of "we're going to rewrite THE system..." is long & littered with red ink.
