Datasets 1. Background Wikipedia has grown into one of the central knowledge sources of mankind and is maintained by thousands of contributors. Wikipedia articles consist mostly of free text, but also contain different types of structured information, such as infobox templates, categorisation information, images, geo-coordinates, and links to external Web pages. Semantic Web I have an idea that I think is very important but I haven’t yet polished to the point where I’m comfortable sharing it. I’m going to share it anyway, unpolished, because I think it’s that useful. So here I am, handing you a dull, gray stone, and I’m saying there’s a diamond inside. Maybe even a dilithium crystal. My hope is that a few experts will see what I see and help me safely extract it.

SPARQL - Semantic Web Standards Overview RDF is a directed, labeled graph data format for representing information in the Web. This specification defines the syntax and semantics of the SPARQL query language for RDF. Resource Description Framework (RDF) / W3C Semantic Web Activity Overview RDF is a standard model for data interchange on the Web. RDF has features that facilitate data merging even if the underlying schemas differ, and it specifically supports the evolution of schemas over time without requiring all the data consumers to be changed. RDF extends the linking structure of the Web to use URIs to name the relationship between things as well as the two ends of the link (this is usually referred to as a “triple”). Using this simple model, it allows structured and semi-structured data to be mixed, exposed, and shared across different applications. This linking structure forms a directed, labeled graph, where the edges represent the named link between two resources, represented by the graph nodes.

SPARQL Query Examples - Knowledge Wiki - Official wiki of Base22 About SPARQL is a query language that is able to retrieve and manipulate data stored in Resource Description Framework (RDF) format. It was made a standard by the RDF Data Access Working Group (DAWG) of the World Wide Web Consortium, and is recognized as one of the key technologies of the semantic web. Contents gromgull Local OpenID no help available Profile for latest GRDDL transformation for RDFa This page is a profile for GRDDL source documents using the latest GRDDL RDFa transform. Currently the use of this profile licenses RDF data extracted by 2008/09/03/RDFa2RDFXML.xsl from an RDFa source. If you want to declare that a document contains RDFa and always uses the latest profile, add this profile to the head of your XHTML: <head profile=" If you want to use a specific version of the transformation, use the specific profile of that version, e.g.: <head profile=" or reference the transformation directly, e.g.: <head profile=" (...) <link rel="transformation" href=" (...)

RDFSharp - Semantic Web Standards (Tool description last modified on 2015-09-7.) Description RDFSharp is a lightweight open source C# framework designed to ease the creation of .NET applications based on the RDF model, representing a straightforward didactic solution for start playing with RDF and Semantic Web concepts. With RDFSharp it is possible to realize .NET applications capable of modeling, storing and querying RDF data. RDFSharp has a modular API made up of four layers:

Resource Description Framework (RDF) Schema Specification 1.0 W3C Candidate Recommendation 27 March 2000 This Version: Latest Version: Previous Version: Editors: What is Cytoscape? Supports Many Standards Cytoscape supports a lot of standard network and annotation file formats including: SIF (Simple Interaction Format), GML, XGMML, BioPAX, PSI-MI, GraphML, KGML (KEGG XML), SBML, OBO, and Gene Association. Delimited text files and MS Excel™ Workbook are also supported and you can import data files, such as expression profiles or GO annotations, generated by other applications or spreadsheet programs. Using this feature, you can load and save arbitrary attributes on nodes, edges, and networks. For example, input a set of custom annotation terms for your proteins, create a set of confidence values for your protein-protein interactions. Public Database Clients

RDF/RDFa RDF/RDFa is major new functionality in Drupal 7 which describes Drupal entities (nodes, user, comments, terms) and their relationship in a format machines can understand. Mappings are defined between local Drupal entities and widely used vocabularies like Dublin Core, FOAF, SIOC, SKOS, etc. These mappings are stored in arrays and can be defined via programming in the modules. They can also be altered the same way as forms, links, etc.

Spark SQL Programming Guide - Spark 1.1.0 Documentation Spark SQL allows relational queries expressed in SQL, HiveQL, or Scala to be executed using Spark. At the core of this component is a new type of RDD, SchemaRDD. SchemaRDDs are composed of Row objects, along with a schema that describes the data types of each column in the row.
