=======
A wordpress plug-in for querying data from a SPARQL endpoint and present results on WP http://wordpress.org/.
# Description
wpsparql is a wordpress plug-in that exposes a series of functionalities to bring content exposed by an sparql endpoint to Wordpress' UI.
# What is sparql?
SPARQL (pronounced "sparkle") 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. SPARQL allows for a query to consist of triple patterns, conjunctions, disjunctions, and optional patterns.
# What is a sparql endpoint?
SPARQL endpoints are services that accept SPARQL queries and return results.
# This plugin is based on wpckan
This plug-in is based on http://github.com/OpenDevelopmentMekong/wpckan/, a wordpress plug-in exposing functionality to pull and present data exposed by a CKAN instance. More about CKAN on http://ckan.org/.
# Features
## Feature 1: Query SPARQL endpoint
wpsparql exposes the shortcode **[wpsparql_query_endpoint query="QUERY"]** which can be used to generate a query and present the results returned by the endpoint.
The shortcode has following parameters:
* **query**: (Mandatory) Term to query the database.
Examples:
```php
[wpsparql_query_endpoint query="SELECT * WHERE { ?person a foaf:Person . ?person foaf:name ?name } LIMIT 1"]
```
```html
person
name
some_url
some_name
```
