Building Semantic Web CRUD operations using PHP

by parmentierf & 1 other
Create, Read, Update, and Delete (CRUD) operations are the most basic database operations, but they are also the most crucial. CRUD operations are typically done using the Structured Query Language (SQL) on relational database systems. As the Web is becoming more and more data-oriented, there is a need to shift from SQL-based CRUD operations to Semantic Web-based CRUD operations. Learn how to use PHP to perform CRUD operations over the Semantic Web.

MaRVIN: a distributed platform for massive RDF inference

by parmentierf
Naming: Marvin is named after Marvin, the paranoid android from the Hitchhiker’s Guide to the Galaxy. Marvin has “a brain the size of a planet”, which he is seldomly able to use. Indeed, the true horror of Marvin's existence is that no task he could be given would occupy even the tiniest fraction of his vast intellect.

ARQ - Property Paths

by greut

A property path expression (or just 'path') is similar to a string regular expression but over properties, not characters. ARQ determines all matches of a path expression and binds subject or object as appropriate. Only one match is recorded - no duplicates for any given path expression, although is the path is used in a situation where it's initial points is already repeated in a pattern, then this duplication is preserved.

by parmentierf & 1 other
Le moteur d’inférence qui va rajouter des nouvelles informations à partir des informations existantes est le composant pour lequel il n’y a pas d’équivalent dans le monde SGBD (1); c’est lui qui vient donner tout son sens au reste de la pyramide des technos (XML, URI, RDF, OWL), en interprétant et “motorisant” une ontologie.

2008-10-15: The Semantic Web Deployment Working Group and the XHTML2 Working Group published the W3C Recommendation RDFa in XHTML: Syntax and Processing. This specification allows publishers to express structured data on the Web within XHTML. This allows tools to read it, enabling a new world of user functionality, allowing users to transfer structured data between applications and web sites, and allowing browsing applications to improve the user experience. For those looking for an introduction to the use of RDFa and some real-world examples, please consult the updated RDFa Primer. Learn more about the Semantic Web Activity and the HTML Activity.
