Indeed - this fits into the need for work on mappings and to address the different kinds of identifiers in different databases as a basis for integration across heterogeneous data sources. > On 12 Mar 2019, at 09:28, Ivan Herman <ivan@w3.org> wrote: > > Hugh, > > I agree with Juan that these are questions for step 9:-) > > However, one data point: as far as I can see and understand, the Property Graph model does not put the kind of emphasis RDF does on the usage of URI-s for the nodes and links.
