A retrospective on the development of the RDF/XML Revised Syntax
نویسنده
چکیده
This paper reviews the process that was undertaken in revising the transfer syntax for RDF as defined in the RDF Model and Syntax W3C Recommendation[1] by the RDF Core Working Group[2] and the problems that are now clear especially comparing the revised RDF model and new abstract syntax. The syntax looks out of date in particular with the use of XML QNames giving unconstrained syntax terms in the XML, causing problems with newer XML technology such as XSLT, DTDS and W3C XML Schema[3] and other XML-constraining languages. In order to deliver a modern RDF syntax, this paper reviews the requirements for RDF in two aspects – as a canonical transfer syntax and one for end-users, targeted at HTML. It evaluates previous RDF syntax proposals against these requirements and analyses the pros and cons of XML and non-XML syntaxes. The conclusion is a summary of syntax approaches for future standardisation activity.

TriX : RDF Triples in XML
Many approaches to writing RDF in XML have been proposed. The revised standard RDF/XML still has many known problems. It is not intrinsically difficult to have a clear serialization of RDF in XML, and we present a simple solution. We add the ability to name graphs, noting that in practice this is already widely used. We use XSLT as a general syntactic extensibility mechanism to provide human fr...

متن کاملFrom XML to RDF: Syntax, Semantics, Security, and Integrity (Invited Paper)
In this paper we evaluate security methods for extensible Markup Language (XML) and the Resource Description Framework (RDF). We argue that existing models are insufficient to provide high assurance security for future Web-based applications. We begin with a brief overview of XML access control models, where the protection objects are identified by the XML syntax. However, these approaches are ...

متن کاملOWL rules: A proposal and prototype implementation
Although the OWL Web Ontology Language adds considerable expressive power to the Semantic Web it does have expressive limitations, particularly with respect to what can be said about properties. We present SWRL (the Semantic Web Rules Language), a Horn clause rules extension to OWL that overcomes many of these limitations. SWRL extends OWL in a syntactically and semantically coherent manner: th...
