Ontologies and the Semantic Web

Fri, 30 Dec 2016 06:44:09 +0000

A video lecture introducing RDF Schema and OWL, with visible slides throughout. The concepts behind ontologies are also discussed in a general, schema-agnostic manner. Places these technologies within the larger context of the Semantic Web.

XSD (XML Schema Definition)

Thu, 24 Nov 2016 05:51:18 +0000

This slide presentation explains that the purpose of an XML Schema is to define the legal building blocks of an XML document, just like a Document Type Definition (DTD). Explains the difference between the simple and complex element types. Also covers attributes, restrictions, enumeration, and indicators.

Coloring RDF Triples to Capture Provenance

Wed, 23 Nov 2016 05:50:22 +0000

Recording provenance information of RDF triples aggregated from different heterogeneous sources is crucial in order to effectively support trust mechanisms, digital rights and privacy policies. Managing provenance becomes even more important when we consider not only explicitly stated but also implicit triples (discovered through RDF Schema inference rules) in conjunction with declarative languages for querying and updating RDF graphs. This paper proposes a method which relies on colored RDF triples represented as quadruples to capture and manipulate explicit provenance information.

On Explicit Provenance Management in RDF/S Graphs

Sun, 17 Jan 2016 13:56:09 +0000

The notion of RDF Named Graphs has been proposed in order to assign provenance information to data described using RDF triples. This paper argues that named graphs alone cannot capture provenance information in the presence of RDF Schema reasoning and updates. In order to address this problem, the authors introduce the notion of RDF/S Graphsets, in which a graphset is associated with a set of RDF named graphs and contain the triples that are jointly owned by the named graphs that constitute the graphset. They formalize the notions of RDF named graphs and RDF/S graphsets and propose query and update languages that can be used to handle provenance information for RDF/S graphs taking into account RDF Schema semantics.

XML and JSON Data Modeling Best Practices

Sat, 16 Jan 2016 13:43:28 +0000

This brief tutorial demonstrates some best practices to use when modeling data in XML and/or JSON. It covers document sizing and granularity, keeping a data model simple and understandable, and applying envelope patterns. This tutorial is geared for developers using Mark Logic 7 or 8.

Multi-Agent and Semantic Web Systems: RDF Schema

Abi Evans — Fri, 13 Nov 2015 06:00:10 +0000

This slide presentation of lecture material was used as part of a course given at The University of Edinburgh School of Informatics. This lecture introduces RDF Schema and discusses its benefits as well as its constraints and limitations. This includes inference and semantics, entailments, comparisons to OWL (such as the handling of disjointedness), and serializing RDF in XML.

Using HTML Schemas for Semantic Markup Microdata

Abi Evans — Tue, 10 Nov 2015 05:13:00 +0000

This video ooks at the relationship between XML and HTML Schemas. Shows examples of Schema.org, one such library of microdata that can now be incoportated into HTML documents to give specific meaning to the content on our web pages.

Why Use XML Schemas?

Abi Evans — Tue, 10 Nov 2015 02:57:31 +0000

This tutorial presents the case for using XML Schemas: They are more powerful than DTD; Support Data Types; Use XML Syntax; Secure Data Communication; are Extensible; and "Well-formed is not enough (errors can still occur in the absence of validation, even if XML syntax is used)".

Markup Languages and Document Processing: Vocabularies and Queries

Abi Evans — Tue, 10 Nov 2015 02:57:30 +0000

This lesson plan was used for the course "Markup Languages and Document Processing", part of the Master in Informatics and Computing Engineering program at Porto University. Contains Bibliography and Materials (most with links) used to achieve the following learning goals: Describe the class and properties of RDF Schema; Define application profiles as vocabularies designed for a domain and shared in a community; Query ontologies using the SPARQL language.
