Re: Prefixes fn and lfm: URLs broken&In-Reply-To=

[Jesus <je...@gmail.com>]

Hi Sergio,

I get two two differents errors through two possible scenes, declaring or
not the URL namespace definitions explicitly:


** Code option 1 (namespaces explicitly defined) **

@prefix dc: <http://purl.org/dc/elements/1.1/> ;
@prefix fn: <http://www.newmedialab.at/lmf/functions/1.0/> ;
@prefix lmf: <http://www.newmedialab.at/lmf/types/1.0/> ;
id = . :: xsd:string ;
title = dc:title :: xsd:string ;
file = fn:content(.) :: lmf:text_es ;

** Exception obtained **

org.apache.marmotta.ldpath.exception.LDPathParseException: error while
parsing path expression
