Define requirements to map data and object properties and data types

Mapping namespaces and prefixes, data types mismatches /inconsistencies (eg IRIs as strings, different namespaces).

A starting point can be identifying available xrefs in the problem resources.

Start by identifying the available xrefs in the problem resources, then inventory the namespaces, prefixes, properties, and data types involved. Done means the requirements document the mappings needed and explicitly covers mismatches such as IRIs represented as strings and equivalent properties from different namespaces.
