Oak HTTP binding

This is a simple JavaScript- and browser-friendly HTTP binding for Oak. It makes it possible to access and modify content in an Oak repository remotely via the HTTP protocol.

The easiest way to try out this binding is to start an in-memory repository using the oak-run jar:

$ java -jar oak-run/target/oak-run-*.jar

The resulting repository is made available at http://localhost:8080/. The following examples use the httpie client to perform simple CRUD operations. The username and password (by default admin and admin) have been specified in the ~/.netrc file so they are not included on the command lines.

$ http -j -b localhost:8080
{
    "jcr:primaryType": "rep:root",
    "jcr:system": {},
    "oak:index": {},
    "rep:security": {}
}

You can add or modify content by posting JSON:

$ http -j -b localhost:8080/test \
      jcr\\:primaryType=oak:Unstructured foo=abc bar:=123
{
    "bar": "123",
    "foo": "abc",
    "jcr:primaryType": "oak:Unstructured"
}

The jcr:primaryType property needs to currently be included to avoid JCR constraint violations. The intention is to automatically infer the value if not explicitly included. Note also how the first colon needs to be escaped on the command line to prevent httpie from interpreting the argument as an extra HTTP header.

The posted content is stored in the repository and is now accessible:

$ http -j -b localhost:8080
{
    "jcr:primaryType": "rep:root",
    "jcr:system": {},
    "oak:index": {},
    "rep:security": {},
    "test": {}
}

$ http -j -b localhost:8080/test
{
    "bar": "123",
    "foo": "abc",
    "jcr:primaryType": "oak:Unstructured"
}

You can modify the content by posting more data to the same URL:

$ http -j -b localhost:8080/test \
      foo=xyz child:='{"jcr:primaryType": "oak:Unstructured"}'
{
    "bar": "123",
    "child": {},
    "foo": "xyz",
    "jcr:primaryType": "nt:unstructured"
}

$ http -j -b localhost:8080/test/child
{
    "jcr:primaryType": "oak:Unstructured"
}

Finally, content can be removed either by posting a null value to it or by using DELETE:

$ http -j -b localhost:8080/test bar:=null child:=null
{
    "foo": "xyz",
    "jcr:primaryType": "nt:unstructured"
}

$ http -j -h DELETE localhost:8080/test
HTTP/1.1 200 OK
