LDES example

Installation

cp .env.example .env
docker-composer up -d (or docker compose up -d)

Test

Run the following:

curl -v   POST http://localhost/example-stream?resource=https://example.org/person/80325 \
   -H "Content-Type: application/ld+json" \
   -d '{"@context":"https://json-ld.org/contexts/person.jsonld","@id":"https://example.org/person/80325","@type":"Person","name":"John Lennon","born":"2040-10-09","spouse":"http://dbpedia.org/resource/Cynthia_Lennon"}'

Wait for like 30 seconds (or a minute if nothing shows yet)
Go to http://localhost:8890/sparql
Run the following sparql query (you should have john lennon & his wife in resource):

select * where {
   graph <http://mu.semte.ch/application>{
       ?s ?p ?o
   }
}

Now let's make an update:

curl -v   POST http://localhost/example-stream?resource=https://example.org/person/80325 \
   -H "Content-Type: text/turtle" \
   -d '<https://example.org/person/80325> <http://xmlns.com/foaf/0.1/name> "Bob Dylan".'

Wait for a minute or so
Execute the same query as above, you should get Bob Dylan now

Troubleshoot

You may need to restart the consumer, if there's no data it seems it can get stuck sometimes.
