SPARQL - Wikipedi

  1. SPARQL (Aussprache?/i) ist eine graphenbasierte Abfragesprache für RDF. Der Name ist ein rekursives Akronym für S PARQL P rotocol A nd R DF Q uery L anguage. Die RDF Data Access Working Group (DAWG) des World Wide Web Consortiums trieb die Entwicklung und Standardisierung von SPARQL voran
  2. SPARQL (pronounced sparkle , a recursive acronym for SPARQL Protocol and RDF Query Language) is an RDF query language —that is, a semantic query language for databases —able to retrieve and manipulate data stored in Resource Description Framework (RDF) format
  3. SPARQL, pronounced 'sparkle', is the standard query language and protocol for Linked Open Data on the web or for semantic graph databases (also called RDF triplestores). SPARQL, short for SPARQL Protocol and RDF Query Language, enables users to query information from databases or any data source that can be mapped to RDF
  4. SPARQL is a query language and a protocol for accessing RDF designed by the W3C RDF Data Access Working Group. As a query language, SPARQL is data-oriented in that it only queries the information held in the models; there is no inference in the query language itself

  1. SPARQL, Kurzform für SPARQL Protocol and RDF Query Language steht für eine Reihe von Empfehlungen, die das W3C im Januar 2008 verabschiedet hat. SPARQL Query Language for RDF definiert eine Anfragesprache für RDF-Datenbestände. Es werden dabei keine Unterschiede zwischen lokalen und entferten Datenbeständen gemacht. Dies prädestiniert SPARQL für die Verwendung in Szenarien, in denen auf.
  2. utes. All triples are available in the default graph. There are 19 named graphs. Documentatio
  3. SPARQL can be used to express queries across diverse data sources, whether the data is stored natively as RDF or viewed as RDF via middleware. SPARQL contains capabilities for querying required and optional graph patterns along with their conjunctions and disjunctions

SPARQL Spezifikation eines neuen Standard: SPARQL - Protokoll + RDF-Abfragesprache - Kombination aller gute Features aus alle RDF-Anfragesprachen - Produkt der RDF Data Access Working Group (DAWG) des W3C Entwicklungsstufe Candidate Recommendation - SQL ähnliche Syntax (Aber trotzdem sehr verschieden! SPARQL provides an operation to test strings, based on regular expressions. This includes the ability to ask SQL LIKE style tests, although the syntax of the regular expression is different from SQL SPARQL (pronounced sparkle, acronym for S PARQL P rotocol A nd R DF Q uery L anguage) is an RDF query language, that is, a semantic query language for databases. With SPARQL you can extract any kind of data, with a query composed of logical combinations of triples

  1. I don't quite understand why in SPARQL they haven't implemented the basic logic operators. However in most of the cases is possible to obtain the same result in a number of way. The purpose of this question is to have a quick reference for the possible way troughs that can substitute an or statement. Here's what I can think of

  4. SPARQL is quite similar to SQL, however, unlike SQL which requires SQL schema and data in SQL tables, SPARQL can be used on graphs and does not need a schema to be defined initially. In the following example, we will use SPARQL to find out if Fred has any grandchildren. First, define prefixes to URIs with the PREFIX keyword. Next, we use ASK to discover whether Fred has a grandchild, and WHERE.
  5. The basic building block for SPARQL queries is triple patterns. A triple pattern is just like an RDF graph triple, but you can use a variable in any one of the three positions. We use triple patterns to find the matching triples in a graph and variables act like wildcards that match any node
  6. SPARQL stands for SPARQL Protocol and RDF Query Language. SPARQL will look familiar to anyone who has used SQL. Where SQL is for querying relational databases, SPARQL is for querying RDF (or graph) databases. How to get to the SPARQL editor . On the main page of statistics.gov.scot, in the 'Data' tab, inside the 'Tools' menu, there is a link to the SPARQL Query console. Clicking this.

Download SPARQL Engine for free. An implementation (parser/interpreter) of SPARQL, a query language for RDF data that is the current recommendation of the W3C. Allows easy cusomization of the language and plugs in to several popular RDF servers, like Sesame Learn SPARQL SPARQL (pronounced sparkle) is the query language for the Semantic Web. Along with RDF and OWL, it is one of the three core technologies of the Semantic Web. This lesson introduces the SPARQL query language, starting with simple queries. Future lessons will build on this material with more advanced SPARQL concepts. Today's Lesson [ SPARQL/FILTER. From Wikibooks, open books for an open world < SPARQL. Jump to navigation Jump to search. OPTIONAL: SPARQL FILTER: UNION: FILTER(condition) is a clause you can insert into your SPARQL query to, well, filter the results. Inside the parentheses, you can put any expression of boolean type, and only those results where the expression returns true are used. Contents. 1 FILTER on. SPARQL (pronounced sparkle, a recursive acronym for SPARQL Protocol and RDF Query Language) is a set of specifications by W3C that provide languages and protocols to query and manipulate RDF graph content on the Web or in an RDF store RDF* and SPARQL* (new in RDF4J 3.2) RDF4J has (experimental) support for RDF* and SPARQL*. RDF* and its companion SPARQL* are proposed extensions to the RDF and SPARQL standards (see Olaf Hartig's position paper) to provide a more convenient way to annotate RDF statements and to query such annotations.In essence, RDF* attempts to bridge the gap between the RDF world and the Property Graph world

SPARQL ist eine Abfragesprache zum Abfragen von RDF Daten (Resource Description Framework). Es ähnelt SQL für relationale Daten in Datenbanken.. Dieses Live-Training (vor Ort oder per Fernzugriff) richtet sich an technische Personen, die RDF Daten abfragen möchten, die in einer Semantic Web Datenbank gespeichert sind.. Am Ende dieser Schulung können die Teilnehmer SPARQL-Gremlin is a compiler used to transform SPARQL queries into Gremlin traversals. It is based on the Apache Jena SPARQL processor ARQ, which provides access to a syntax tree of a SPARQL query. The current version of SPARQL-Gremlin only uses a subset of the features provided by Apache Jena. The examples below show each implemented feature. Quick Start. Console Application. The project.
