The dexterous nature of an entity relationship model endowed with 
machine comprehensible entity relationship semantics ultimately lends 
itself to mapping. We (OpenLink Software) have mapped more than a 100 
different data source and protocol combinations to RDF, over the years.

As per my earlier reference, the shortcut to understanding this reality 
goes back to Peter Chen's 1976 dissertation [1] about the entity 
relationship model. The model that RDF improves upon by adding:

1. machine comprehensible entity relationship semantics
2. use of URIs to denote entities in this model .

Linked Data further enhances this via use of de-referencable URIs. 
TimBL's variant of Linked Data [2] basis this specifically on HTTP URIs.

Entity Relationship Model to achieve a unified view of disparate data

Linked Data meme .
