Linked Data Subject Blocks implementation Today
742
This container offers Linked Data Subject pages based on a sparql endpoint based on the current view of the item. It does not support chains as a Linked Data Subject Block chain is intended to do. However, it implements the urls that are to be supported to retrieve the information in different serializations.
The service connects to other services, which should be declared as accessible hosts:
The service URLs are given by the following environment variables
| Environment variable | default value |
|---|---|
| ENV_SPARQL_ENDPOINT_SERVICE_URL | http://sparql-endpoint-service:8890/sparql |
| Environment variable | default value | comment |
|---|---|---|
| ENV_URI_PREFIX | https://data.vlaanderen.be | use prefix to cope with http/https issue |
| ENV_URI_DOMAIN | data.vlaanderen.be | deprecated over ENV_URI_PREFIX |
| ENV_SPARQL_VIRTUOSO | a setting with allows to customize the sparql-template for Virtuoso. Example see below. | |
| ENV_SERVERNAME | ldsb-data.vlaanderen.be | |
| ENV_LOGLOCAL | false | set true to log on disk |
| ENV_CONTEXTMAP | file:///config/context.map | a mapping between the concepts and their jsonld context definition |
###Example ENV_SPARQL_VIRTUOSO
This environment variable is a placeholder at the start of a SPARQL template. Virtuoso has the ability to configure the scope of the query by virtuoso specific constructs. This variable allows to insert statements of the following form.
ENV_SPARQL_VIRTUOSO define input:default-graph-exclude <http://data.vlaanderen.be/id/dataset/muuuid>
Assume docker is installed.
Let LOCALDIR be this directory.
docker build . -t subjectblocks
starts the service name ldsb
docker run -p81:80 -d --name ldsb \ -v /home/vagrant/OSLO/github/LinkedDataSubjectBlocks/webservice-today/logs:/logs \ --add-host sparql-endpoint-service:13.93.84.96 subjectblocks
quickest way to stop the service
docker exec -it ldsb service apache2 stop
tail the error log
docker exec ldsb tail -f /var/log/apache2/error.log
