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.
