Webscaled: Data marketplace - Buy and sell data

Tag: Sparql

To all my fellow Python enthusiasts, Ivan Herman (with the help of new programmers from the CTIC Foundation in Spain) has released a new version of his SPARQL wrapper for Python. The wrapper creates the query URI for you and will convert the results to RDF/XML and JSON, if possible. Keep up the excellent work guys, we can never have enough Semantic Web libs for Python!

The RDF Data Access Working Group has published the following three SPARQL Proposed Recommendations:

SPARQL Query Language for RDF
Defines the syntax and semantics of the SPARQL query language for RDF. The results of SPARQL queries can be results sets or RDF graphs.
SPARQL Query Results XML Format
Defines an XML format for the variable binding and boolean results formats.
SPARQL Protocol for RDF
Uses WSDL 2.0 to describe an HTTP protocol for conveying SPARQL queries to an SPARQL query processing service and returning the query results to the party that made the request.

Hey everyone, I've gathered some good reading material for your enjoyment! If you're new to the Semantic Web or just want to brush up on your knowledge then take a look at the following articles. Listed below are over thirty introductions, primers, references, guides, and tutorials on the Semantic Web, RDF, OWL, SPARQL, and GRDDL. If you know of other articles that would fit well here leave me a comment and I'll be happy to add them to the list. Enjoy!

Microsoft has taken steps in the direction of supporting Semantic Web standards such as RDF, OWL, and SPARQL. While their support is minimal and not hyped very broadly it is still nice to see the them implementing these standards in their software. I also haven't seen any evidence that they wish to formulate a proprietary brand of these standards, so I have no complaints.

Appmosphere RDF ClassesARC is a lightweight, SPARQL-enabled RDF system for mainstream Web projects. It is written in PHP and has been optimized for shared (or performance- or privilege-limited) Web environments. ARC facilitates the integration of RDF and SPARQL into PHP/MySQL frameworks.

ARC is a very well documented project, which I think is important for its success. Their documentation is clear, concise, and provides plenty of inline sample code to examine as you read and learn.
