The OSI-model

after reading a paper about the OSI-model I'm not exactly sure how to look at this model.

Does data (a file) travel from the application level "down" each layer at the client

Application
V
Presentation
V
Session
V
Transport
V
Network
V
Data link
V
|
|
| (Physical)
|

and "up" each layer (in reverse order: physical, data link, network etc..) at the server ?

After taking a look at a picture (http://www.cs.columbia.edu/~hgs/internet/it_stack.gif)
I noticed that there seems to be no data link activity between the
network (IPv4, IPv6) and physical layer (Ethernet)..

I couldn't be more confused. Any help at all is highly appreciated Smilie

OWL::DirectSemantics::Translator(3pm)			User Contributed Perl Documentation		     OWL::DirectSemantics::Translator(3pm)

NAME
OWL::DirectSemantics::Translator - lift an OWL2 model from an RDF model SYNOPSIS
use RDF::Trine; my $model = RDF::Trine::Model->temporary_model; RDF::Trine::Mode->parse_url_into_model($url, $model); use OWL::DirectSemantics; my $translator = OWL::DirectSemantics::Translator->new; my $ontology = $translator->translate($model); DESCRIPTION
This translator is only about 90% complete. Constructor "new" Creates a new translator object, primed and ready for action! Method "translate($model [,$ontology_node])" Translates the data in the RDF::Trine::Model provided into OWL, returning an OWL::DirectSemantics::Element::Ontology object. The model is generally assumed to contain a single ontology. $ontology_node is an optional RDF::Trine::Node object containing the ontology's URIor blank node identifier. $model will be modified by the translation process. Any triples translated to OWL are removed from the model. Any triples remaining are ones that could not be translated. (If the model provided is OWL DL-compatible, there should be no triples remaining after translation.) SEE ALSO
