Posting them to a triplestore will be basically the same for different triplestores, with only the triplestore URL changing:

curl -X POST -H "Content-Type: text/turtle" --data-binary @event1.ttl http://localhost:3030/test/data |

The command to execute the SPARQL Update vary somewhat more depending on the triplestore used, since some triplestores require form-encoding of SPARQL Update commands and others accept them directly:
| Code Block |
|---|
| language | bash |
|---|
| title | fuseki_sparql.sh |
|---|
|
curl -X POST -H "Content-Type: application/sparql-update" -d @event2.sparql http://localhost:3030/test/update |
| Code Block |
|---|
| language | bash |
|---|
| title | sesame_sparql.sh |
|---|
|
curl -X POST -H "Accept-Encoding: identity" -H "Accept: */*" -H "Content-Type: application/x-www-form-urlencoded" -d update=`cat event2.sparql` http://localhost:8081/openrdf-sesame/repositories/test/statements |
Adding Events to the Repository
External audit events can be added to an LDP Container as a repository resource. When using Internal Audit Events, the audit container will be created automatically. Otherwise, a container for audit events can be created in the usual way:
| Code Block |
|---|
|
curl -X POST -H "Slug: audit" http://localhost:8080/fcrepo/rest/ |
For each event, post the RDF for the event to the audit container:
| Code Block |
|---|
|
curl -X POST --data-binary @audit_event.ttl -H "Content-type: text/turtle" http://localhost:8080/fcrepo/rest/audit/ |
| Code Block |

The events generated by creating these nodes can be suppressed by Configuring a JMS Event Filter to suppress events about audit:ExternalEvent nodes.
