Wrapper for Products.ZSPARQLMethod

Latest Version: 3.3

http://ci.eionet.europa.eu/job/eea.sparql-www/badge/icon http://ci.eionet.europa.eu/job/eea.sparql-plone4/badge/icon

EEA Sparql is a plone product for fetching data from Linked open data servers (sparql endpoints).

Introduction

It is simple to use, you only have to specify the sparql endpoint url and the sparql query. The results will be converted in an exhibit json, what can easily be reused (ex. by eea.daviz).

Main features

The main features are:

  1. create sparql queries
  2. create sparql bookmark folders, sparql queries are created automatically, and can be synchronized manually or automatically (with a cronjob). If a query is changed, a new version of the object is created, so older ones are not lost.
  3. results are downloadable in various formats: JSON, Exhibit JSON, HTML, XML, XML with Schema, CSV, TSV

Installation

To install eea.sparql into the global Python environment (or a workingenv), using a traditional Zope 2 instance, you can do this:

  • When you're reading this you have probably already run easy_install eea.sparql. Find out how to install setuptools (and EasyInstall) here: http://peak.telecommunity.com/DevCenter/EasyInstall

  • If you are using Zope 2.9 (not 2.10), get pythonproducts and install it via:

    python setup.py install --home /path/to/instance
    

    into your Zope instance.

  • Create a file called eea.sparql-configure.zcml in the /path/to/instance/etc/package-includes directory. The file should only contain this:

    <include package="eea.sparql" />
    

Alternatively, if you are using zc.buildout and the plone.recipe.zope2instance recipe to manage your project, you can do this:

  • Add eea.sparql to the list of eggs to install, e.g.:

    [buildout]
    eggs = eea.sparql
    
  • Tell the plone.recipe.zope2instance recipe to install a ZCML slug:

    [instance]
    recipe = plone.recipe.zope2instance
    zcml = eea.sparql
    
  • Re-run buildout, e.g. with:

    $ ./bin/buildout
    

You can skip the ZCML slug if you are going to explicitly include the package from another package's configure.zcml file.
