the syntax of the prfix command

Hallo,

 

 

I am creating semantics using protege.

I run into some differences for the naming convention for the prefix lines,

and I did not found any explanation on the net:

 

1.       Some with a trailing hash ("#")

2.       And some with a trailing slash ("/")

 

Form http://de.wikipedia.org/wiki/Turtle_%28Syntax%29 I took these examples

 

@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .

@prefix dc: <http://purl.org/dc/elements/1.1/> .

@prefix ex: <http://example.org/stuff/1.0/> .

 

3.) Is it possible to use NO TRAING character (no slash or hash) , too?

 

What is the difference between 1,) and 2.) ???

Is 3.) possible, to?

 

 

 

Yours,

  F. Haferkorn
