Anja, Richard, (ccing the Library Linked Data list) Really great work! Adding to Rinke's comment, I'm also happily surprised by the coherence that you still can give to the various parts of the LOD cloud: the colored version is really fascinating to see [1]. Our core library linked data core

Hi, is there a legend to the coloured cloud, which explains a bit the coloured clusters, or did I simply missed it? (it would be nice, if this legend is directly included in the graphic) Cheers, Bob Am 23.09.2010 10:09, schrieb Antoine Isaac: Anja, Richard, (ccing the Library Linked Data

Any objections against using xsd:anySimpleType or rdfs:Literal as the rdfs:range for OWL datatype properties?

Dear all: Are there any theoretical or practical problems caused by defining the range of an owl:DatatypeProperty as http://www.w3.org/2001/XMLSchema#anySimpleType or http://www.w3.org/2000/01/rdf-schema#Literal ? I think both should be valid (and are useful) in OWL DL ontologies,

Hi all: Thanks! So I understand that for an owl:DatatypeProperty that may hold xsd:float, xsd:integer, xsd:int, xsd:double, or xsd:decimal values, the simplest solution is rdfs:Literal. Is that correct? xsd:decimal would include xsd:integer and xsd:int (?), but there is no standard

NB: It seems that OWL 2 supports DataUnionOf( xsd:float xsd:decimal ) The question is how broadly current apps and repositories already support OWL 2, in particular at Web scale, outside of small, controlled environments. So I guess rdfs:Literal is the better choice for the moment.

Using xsd:simpleType would discard the case of using XML Literal (for example a GML encoded Geometry). Literal seems to be a safer bet. I wish to see in a future version of RDF, a mechanism to valid XML literal with an XML schema complex type or element. I think a datatype should only be
