Re: Literature on semantic web and similar models

Dear Milton,

just off the cuff (I hope this was the level of analysis you were looking for):

RDF and semantic web
in my opinion, this is a good article about the linking of RDF with ontologies and so, in a sense, between the linked-data and semantic-web communities*: http://www.cs.ox.ac.uk/people/ian.horrocks/Publications/download/2008/Horr08a.pdf

* this distinction is not standard, but I think it can be drawn to a certain extent: on one side, the LOD community, using RDF mainly for inter-operability purposes; on the other side, the semantic web community, which is more ground within the formal logic and AI tradition, and which prefers OWL more than generic RDF as modeling language.

Another great doc on the formal issues behind querying RDF is: http://www.w3.org/TR/sparql11-entailment/  in which SPARQL 1.1 entailment regimes are discussed.

In general, finding presentations of the formal underpinning of "generic" RDF (other than the W3C docs, which are by the way excellent) is in general harder. Maybe someone else has suggestions about this?

OWL and and first order logic
On the relationship between description logics and FOL (and hence the relational model): http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.58.8255
I recommend in general Ian Horrock's overview articles for those who are interested in the formal underpinning of OWL. Look especially on the differences between semantic assumptions (such as closed world assumption). This path can lead to the connections with the Datalog/Prolog world.

Linked data and Big Data
On the relationship between linked data and big data: http://www.fujitsu.com/uk/Images/Linked-data-connecting-and-exploiting-big-data-(v1.0).pdf

XML and RDF
There is a debate going on about the limitations of XML over RDF, but I don't have specific references (apart from noting that XML, when used as a data model (and not merely as a syntax), can only represent tree-like models).
