Dear Wiki user, You have subscribed to a wiki page or wiki category on "Clerezza Wiki" for change notification.
The "LinkedDataPlatform" page has been changed by RetoBachmannGmuer: http://wiki.apache.org/clerezza/LinkedDataPlatform?action=diff&rev1=1&rev2=2 * 4.1.7 LDPR representations should have at least one rdf:type set explicitly. This makes the representations much more useful to client applications that don’t support inferencing. + Partially. Resources generated by Clerezza conform to the requirement but its possible to insert arbitrary data. + The description of any named resource in the content graph is served if a get request for that resource is sent against the clerezza instance and the URI is not handled by a dedicated Jax-RS resource and the resource if not of a type for which a Typehandler is registered. When addin triples to the content graph there's no mechanism enforcing that all named resources have an RDF type statement. - 4.1.8 Predicate URIs used in LDPR representations should be HTTP URLs. These predicate URIs must identify LDPRs whose representations are retrievable. LDPR servers should provide an RDF Schema [RDF-SCHEMA] representation of these predicates. + * 4.1.8 Predicate URIs used in LDPR representations should be HTTP URLs. These predicate URIs must identify LDPRs whose representations are retrievable. LDPR servers should provide an RDF Schema [RDF-SCHEMA] representation of these predicates. + + Partially. Triples generated by Clerezza should conform to the requirement but its possible to insert arbitrary data. As arbitrary triples can be uploaded there's no mechanism enforcing meaningfull dereferenceability of the type statements. + * 4.1.9 LDPR representations must use only the following standard datatypes. RDF does not by itself define datatypes to be used for literal property values, therefore a set of standard datatypes based on [XMLSCHEMA11-2] and [RDF-PRIMER] are to be used: xsd types + rdf-xml + + Partially. With the exception of the WebId module [verify] literals generated by Clerezza conform to the requirement but its possible to insert arbitrary data. + + * 4.1.10 LDPRs must use at least one RDF triple to represent a link (relationship) to another resource. In other words, having the source resource’s URI as the subject and the target resource’s URI as the object of the triple represent the link (relationship) is enough and does not require the creation of an intermediate link resource to describe the relationship. + + [REC!] This requirements seems to imply that the properties have a preferred direction, which contradict http://dig.csail.mit.edu/breadcrumbs/node/72. Clerezza does not currently enforce a link it is possible to add to the contentgraph a triple with a subject IRI not otherwise used and a literal object. The resources generated by clerezza do have at least a type statement, would this qualify as link? +
