Linked Data fidelity.

The goal is webby structured data integrated into the innermost sanctum 
of the Web via URIs that have the dual effect of denoting things and 
identifying locations of the description of the descriptions of the 
things they denote [1][2].

Unfortunately, in an attempt to hide raw URIs, many Linked Data 
visualization efforts end up throwing out the baby with the bath water 
i.e., URIs get discarded rather than being associated with labels using 
<a/>  or <link/> relations within <head/>.

The pattern above enables discovery and exploitation of Linked Data URIs 
via user agents (e.g., browsers) and humans (who can then mouse over 
text anchored with a Linked Data URI based hyperlink or just click).

The organization in question should keep the Linked Data URIs its 
consumed from the LOD cloud (and any other public Linked Data sources) 
discoverable to user agents and humans, as per my comments above. Of 
course, they can do whatever with their private Linked Data.

No, the pattern I am suggesting is all about making Linked Data 
discoverable from basic Web pages where said pages are providing a 
presentation of data accessed from public Linked Data sources.

That's not my point. As I've stated in the past, this is about the best 
of both worlds i.e., "horses for courses" compliance :-)


1. -- DBpedia URIs and explicit indirection
2. -- hash URIs as implicit indirection.
