Comments on: Why reading DataViewer pages instead of conventional web pages?

In response to Georgi’s question:
“could you elaborate on an example in which the Zitgist Browser / DataViewer enables me (the end-user) to do something I couldn’t do by reading web documents or even do something faster than by reading web documents”�

My response:
First, the current Document Web ultimately quantifies the number of documents (at a give point in time) containing relevant or irrelevant information (to me) that I will never find the time to read.

An RDF Data Viewer such as the one from Zitgist, enables me to establish a bookmark in the Document Web from which to BEAM a Structured Data Query using a query language such as SPARQL (directly or indirectly).

I can do this becuase the Data Viewer exposes the URIs of the Data Sources

User Generated Content is growing exponentially at an ever increasing rate. Time remains a constant (24 hrs in a day). Thus, the sooner I can BEAM queries down the Giant Global Graph that is the Web, the sooner I return to my pursuit of being, or remaining, a realtime Netizen

Yeah, in fact the thing here is that there is no templates yet defined for owl:Class (and owl:Ontology), etc. In such a case, the viewer use a more or less generic template (depends on cases) to create the document. So it explains the situation.

However, as soon as we define templates to display ontologies stuff, then this case would be resolved.

Take care,

Well, I am probably interpreting the output incorrectly, but I would think that the SubclassOf reference would more or less encapsulate the class reference to promyelocyte (layered data, cfr.RDFa primer) and the restriction about the property, but it seems to mention the concept defined on that page instead. But nevertheless, great service...

Hi,

Well, it seems to be working here. Could you tell me what information is missing? I quickly checked and it was looking good according to what was defined in the neutrophilic promyelocyte page.

Thanks!

Take care,

Fred

Apparently, the Dataviewer does extract RDFa out of valid xHTML pages, so it is possible to feed regular XHTML pages to it (as long as the markup is valid, which is far from conventional web pages of course: example Dataviewer query on an (RDFa)-XHTML page If may may say so: see also this related post: Integrating OWL-RDFS in xHTML
