- Install the OpenSKOS code =============================================================================== Copy the code to a location of your choice.
Make sure all files are readable by your webserver. Make sure the directories
public/data/icons/uploads are writable for the webserver.
For security reasons you can place the
data directory outside your
webserver's document root.
Run composer install to install some dependencies like zend framework 1.12
To configure OpenSKOS you have to rename:
Now you can edit the
You can have separate config settings for specific deployments. The
configuration section marked by the Environment Variable
2.1 Setting Up Your VHOST). Most settings are self explanatory.
If you experience any problems you may want to modify settings in the config, to show you more verbose error messages:
resources.frontController.params.displayExceptions=1 phpSettings.display_errors = 1
1.2.1 OAI-PMH setup
OpenSKOS includes a OAI harvester. To configure OAI Service providers, use the "instances" part of the configuration. Two types of instances are supported:
- openskos (instances of OpenSKOS)
- external (any OAI-PMH provider that provides SKOS/XML-RDF data)
The setup for "openskos" types is easy:
instances.openskos.type=openskos instances.openskos.url=http://HOSTNAME instances.openskos.label=YOUR LABEL
For "external" types use this syntax:
instances.example1.type=external instances.example1.url=http://HOSTNAME instances.example1.label=EXAMPLE LABEL #optional, default=oai_rdf instances.example1.metadataPrefix=METADATAPREFIX #optional: instances.example1.set=SETSPEC
You can define multiple instances by using a different key (in the above example
example1 is used).
- Webserver with PHP support =============================================================================== You can install your favourite webserver with PHP support. All development and testing was done using Apache/2.2.15 with PHP 5.3.8 Make sure your PHP installation supports at least one supported Database adapters (see http://framework.zend.com/manual/en/zend.db.adapter.html)
2.1 Setting Up Your VHOST
The following is a sample VHOST you might want to consider for your project.
<VirtualHost *:80> DocumentRoot "/PATH/TO/CODE/public" ServerName YOUR.SERVER.NAME # This should be omitted in the production environment SetEnv APPLICATION_ENV development <Directory "/PATH/TO/CODE/public"> Options Indexes MultiViews FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory> </VirtualHost>
- Database setup =============================================================================== Install your choice of Zend Framework supported Database engine (see http://framework.zend.com/manual/en/zend.db.adapter.html). The credentials to access your database can be configured in the application's configuration.
Once you have created an empty database, you have to run the SQL script
APPROOT/data/openskos-create.sql to create the db-tables.
You also have to run the php-script to create a tenant:
php APPROOT/tools/tenant.php --code INST_CODE --name INST_NAME --email EMAIL --password PWD create
With this account created you can login into the dashboard, where you can manage all the other entities of the application.
- Apache Jena Fuseki setup =============================================================================== Openskos uses Fuseki 2 for storage. At the time of writing this doc latest stable version is 2.3.0
Installing Fuseki 2 for development purposes:
Download Fuseki 2 from here download
Install stand alone fuseki server. The instructions are the same as on getting started page
Unpack the downloaded file with
tar zxfvto a
<fuseki folder>of your choice
chmod +x fuseki-server
Symlink or copy the content of:
<fuseki folder>and run the server with
The docs say that Fuseki requires Java 7, but if you have the error
Unsupported major.minor version 52.0try updating your Java, or go for Java 8 directly.
Now you will have the fuseki server up and running on http://localhost:3030/ with "openskos" dataset defined. This is also the default config in openskos'
Apache Solr Setup =============================================================================== You have to have a java VM installed prior to installing Solr! Download a 3.4 release of Apache Solr and extract it somewhere on your server: http://www.apache.org/dyn/closer.cgi/lucene/solr/
- go to the
exampledirectory and create a directory named
- copy the
data/solr/confdirectory of the OpenSKOS checkout to the
You can now start Solr (in this example with 1,024 MB memory assigned):
java -Dsolr.solr.home="./openskos" -Xms1024m -Xmx1024m -jar start.jar
- Data Ingest
Once you have the application running you can start adding data,
You can create a collection in the dashboard.
There are three ways to populate a collection:
Send data via the REST-API, e.g. like this:
curl -H "Accept: text/xml" -X POST -T sample-concept.rdf http://localhost/OpenSKOS/public/api/concept
You find the required format of the input data described in the API-docs under: http://openskos.org/api#concept-create
You may send only one concept per call. Also, you have to identify the tenant and provide the API key, which you assign to the user in the dashboard.
Upload a dataset (a SKOS/RDF file) via a form in the dashboard:Manage collections.
Here you can provide many concepts within one file (XPath:
Once you successfully upload the file, it is scheduled for import, as seen in dashboard:Manage jobs.
The import job can be started with
a CLI script intended to be run with a Cron like task runner.
6.3 OAI ???
Third possiblity is to replicate an existing dataset via OAI-PMH, either from other OpenSKOS-instances or from an external source providing SKOS-data.
??? For this, you set the [OAI baseURL]-field of a collection to the OAI-PMH endpoint of an external provider and let the source be harvested.
The harvest job can be started with ./tools/harvest.php, another CLI script meant to be run as a cron-task. ???
6.4 Migrate from OpenSKOS v1
It is possible to migrate the data from the SOLR core used by a OpenSKOS v1 instance directly into a v2 instance
tools/migrate.php --endpoint http://<solr server>:8180/ciss/<core name>/select
Once this is complete the data from the v1 instance will be available in the triple store used by OpenSKOS v2.
