API quick reference

Examples

Compact API

HTTP GET requests can be made to URIs of the shape

http://.../format/input-uri

The response is the input document converted to the desired output format.

Form-style GET API

HTTP GET requests can be made to the URI http://.../ with the following query parameters:

uri	URI of an input document
format	Desired output format; defaults to `best`

The response is the input document converted to the desired output format.

Direct POST API

HTTP POSTing a document body to http://.../format will convert the document to the specified output format. The media type of the input has to be specified in the Content-Type HTTP header. Depending on the servlet container, a Content-Length header specifying the length of the input document in bytes might also be required. Typical media types for supported input formats are:

Input format	Media type
HTML	`text/html`
RDF/XML	`application/rdf+xml`
Turtle	`text/turtle`
N-Triples	`text/plain`
N-Quads	`text/plain`

Example POST request:

POST /rdfxml HTTP/1.0
Host: example.com
Content-Type: text/turtle
Content-Length: 174

@prefix foaf: <http://xmlns.com/foaf/0.1/> .

[] a foaf:Person;
    foaf:name "John X. Foobar";
    foaf:mbox_sha1sum "cef817456278b70cee8e5a1611539ef9d928810e";
    .

Form-style POST API

A document body can also be converted by HTTP POSTing form data to http://.../. The Content-Type HTTP header must be set to application/x-www-form-urlencoded. The following parameters are supported:

type	Media type of the input, see the table above. If not present, auto-detection will be attempted.
body	Document body to be converted
format	Desired output format; defaults to `best`

Output formats

Supported output format identifiers are:

best for content negotiation according to the client's Accept HTTP header
turtle, ttl, n3 for Turtle/N3
ntriples, nt for N-Triples
nquads, nq for N-Quads
rdfxml, rdf, xml for RDF/XML

Error reporting

Processing errors are indicated via HTTP status codes and brief text/plain error messages. The following status codes can be returned:

Code	Reason
200 OK	Success
204 No Content	Extraction from input was successful, but yielded zero triples
400 Bad Request	Missing or malformed input parameter
404 Not Found	Malformed request URI
406 Not Acceptable	None of the media types specified in the `Accept` header are supported
415 Unsupported Media Type	Document body with unsupported media type was POSTed
502 Bad Gateway	Input document from a remote server could not be fetched or parsed

If the Fix checkbox is activated, Any23 tries to fix some common RDFa mistakes before performing the extraction. Fixing is performed according a set of fully customizable rules. Please refer to the developer guide for any further detail.

If the Report and Fix checkboxes are both activated, Any23 wraps the RDF extracted triples with an XML response providing a short report on which RDFa errors have been detected and which rules have been triggered to perform the fix. Please refer to the developer guide for any further detail.
