what you see is what you (maybe) understand...

what you see is what you (maybe) understand... what you see is what you (maybe) understand...

How about the browser?

Look, ma, there’s something in this Web page...

unreliable HTML scrapping to process the data

A better solution?

Look, ma, there’s something in this RSS feed...

XML as lingua franca for data serialization

XML scrapping to assure data reuse

the syntactic Web

from data to information, from information to knowledge

Can we explain this content? what you see is what you (maybe) understand...

Understanding data: persons, events, presentations, photos,... what you see is what you (maybe) understand...

There are plenty of other useful vocabularies... DOAC, DOAP, GoodRelations, SIOC, XMP etc.

RDF as a solution for... storing distributed Web resources denoted by URIs

RDF as a solution for... describing “things” of interest e.g., documents, persons, software, concepts,...

RDF as a solution for... modeling knowledge: taxonomies, thesauri, ontologies

RDF as a solution for... linking and (re)using other existing data in a coherent manner ...see Linked Data initiative

Can I “explain” this content using RDF within HTML? what you see is what you (maybe) understand...

RDF constructs can be used directly into Web pages

RDFa another way to serialize the RDF model

RDFa using (X)HTML to specify RDF triples: subject predicate object rdfa.info
