EEA Sparql ========== EEA Sparql is a plone product for fetching data from Linked open data servers (sparql endpoints). Contents ======== .. contents:: 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" /> .. _pythonproducts: http://plone.org/products/pythonproducts 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.
