- A Predicate-Ordered Sort-Ordered Logic for RDFS
- RDF Schema defines basic ontological modeling primitives on top of RDF. Other Semantic Web languages with richer modeling primitives are to be constructed by extending RDF Schema, among them are OIL, DAML and OWL. However, the layering of Semantic Web languages on RDFS RDF and RDF Schema cannot be achieved...

- SquishQL: The simplest RDF query language
- RDF is a main standard for metadata defining and storage in a Web 2.0 environment. However, most of the query languages are incomplete and fairly complex. However, accessing RDF data is a simple thing when you use SquishQL - an RDF query language with SQL notation. Using several code examples,...

- Taking the RDF Model Theory Out for a Spin
- Entailment, as defined by RDF's model-theoretical semantics, is a basic requirement for processing RDF, and represents the kind of "semantic interoperability" that RDF-based systems have been anticipated to have to realize the vision of the "Semantic Web". This paper investigates the computational aspects of deductive closures of RDF graphs, and...

- Designing and Creating a Web Site Based on RDF Content
- This paper presents a method and a tool for designing and automatically creating an HTML web site for publishing Semantic Web content represented in RDFS. The idea is to specify the needed RDF to HTML transformation on two separate levels. On the HTML level, the layout of the pages can...

- An Assessment of RDF/OWL Modelling
- The Semantic Web initiative offers a set of standards (RDF, RDFS and OWL) for the representation and exchange of information. This paper addresses the question of what sorts of modelling problems these standards can be most fruitfully applied to. What benefits can be gained from using them? What are the...

- A Logic-Based RDF to HTML Generator for Spinning the Semantic Web
- This paper considers the problem of rendering RDF content for the human user by transforming RDF descriptions into a repository of semantically indexed and linked HTML pages. This paper presents a two level method for such a transformation: On the HTML level, the layout of the pages can be described...

- RDF Support in Oracle
- Resource Description Framework RDF is a standard for representing information that can be identified using a Universal Resource Identifier URI. In particular, it is intended for representing metadata about Web resources. RDF provides the basic building blocks for supporting the Semantic Web. The simplicity of its structure promotes interoperability across...

- A Possible Simplification of the Semantic Web Architecture
- In the semantic web architecture, Web ontology languages are built on top of RDFS. However, serious difficulties have arisen when trying to layer expressive ontology languages, like OWL, on top of RDF-Schema. Although these problems can be avoided, OWL and the whole semantic web architecture becomes much more complex than...

- RDF and Contexts: Use of SPARQL and Named Graphs to Achieve Contextualization
- The very simple structure of the RDF data model and semantics can lead to a number of issues when more complex scenarios are supposed to be represented in RDF. Aspects such as temporary evolution of a knowledge base, relevance and trust require more than just a model that consists of...

- The Semantic Web as a Semantic Soup
- The Semantic Web is currently best known for adding metadata to web pages to allow computers to 'Understand' what they contain. This idea has been applied to people by the Friend of a Friend project which builds up a network of who people know through their descriptions placed on web...

- The Yin/Yang Web: A Unified Model for XML Syntax and RDF Semantics
- XML is the W3C standard document format for writing and exchanging information on the Web. RDF is the W3C standard model for describing the semantics and reasoning about information on the Web. Unfortunately, RDF and XML - although very close to each other - are based on two different paradigms....

- Tethering Cultural Data With RDF
- This paper describes a research project leading to the development of a data querying application based on the Jena RDF store. The starting point is a collection of relational databases holding cultural heritage material from the National Collections of Scotland. This source data is a mixture of fixed fields and...

- Semantic Web - Is it ready for prime time?

- D2R MAP - A Database to RDF Mapping Language
- The vision of the Semantic Web is to give data on the web a well-defined meaning by representing it in RDF and linking it to commonly accepted ontologies. Most formatted data today is stored in relational databases. To be able to use this data on the Semantic Web we need...

- XML Schema Registration and Validation
- An XML schema defines the structure of an XML document by setting constraints on the data types of elements and attributes in the document. XML documents can be validated against the XML schema to ensure they conform to the constraints defined in the schema. There are several schema languages that...

- Generating an XML Document From XML Schema With JAXB
- An XML Schema is an XML-based representation of the structure of an XML document. Many J2EE developers use an XML Schema instead of a Document Type Definition DTD to generate an XML document; because unlike DTD, XML Schema supports data types and namespaces. An XML document based on an XML...
