## In short

Argues critically that DSRP functions as a universal grammar of description rather than an ontology, pressing on whether it rules out possible world-structures, yields non-trivial consequences, or generates distinctive predictions; the linked page publishes the resulting full exchange with Cabrera. Counterexamples and resolutions remedy more challenging claims against proposed counterexamples.

## What they found (results)

Concludes DSRP is descriptive rather than adjudicative and that universality alone does not establish an ontological claim; Cabrera counters with an entailment/minimality argument and the M = I·O results, and Mossé revised the series to state the 'structural ontology' framing up front.

## What they set out to do (purpose)

A post documenting a long email exchange between Benjamin Mossé and Derek Cabrera over whether DSRP is genuinely an ontology.

These researchers were not testing DSRP. The finding is theirs; the correspondence to DSRP is drawn by this site.
