EEA Sparql is a plone product for fetching data from Linked open data servers (sparql endpoints).
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).
The main features are:
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:
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
You can skip the ZCML slug if you are going to explicitly include the package from another package’s configure.zcml file.
You will also need a worker instance to be set up. This is required for the async update of the last working results.
For both, normal and worker instances, the plone.app.async should be added in the EGG slug:
eggs = ... plone.app.async
For the normal instances, the plone.app.async-single_db_instance should be added in the ZCML slug:
zcml = ... plone.app.async-single_db_instance
For the worker instances, the plone.app.async-single_db_worker should be added in the ZCML slug:
zcml = ... plone.app.async-single_db_worker
Re-run buildout, e.g. with:
