Converter: commON

The Converter: commON Web service is used to convert commON data into structXML (the internal structWSF DTD structure). It is not yet implemented to convert RDF+XML, RDF+n3 or structXML into commON data. Currently, the only goal is to import commON data into structWSF nodes, but it will be extended in the future.

All converter Web services endpoints are used to convert multiple kinds of data and to make the bridge between a structWSF and other existing systems that understand these formats.

Developers communicate with the Converter: commON Web service using the HTTP POST method. You may request one of the following mime types: (1) text/xml (which is structXML). The content returned by the Web service is serialized using the mime type requested and the data returned depends on the parameters selected.

Usage
This Web service is intended to be used by content management systems, developers or administrators to manage access to WSF (Web Service Framework) resources (users, datasets, Web services endpoints).

Web Service Endpoint Information
This section describes the permissions you need in the WSF (Web Service Framework) to send a query to this Web service endpoint, and it describes how to access it.

To access this Web service endpoint you need the proper CRUD (Create, Read, Update and Delete) permissions on a specific graph (dataset) of the WSF. Without the proper permissions on this graph you won't be able to send any queries to the endpoint.

Needed registered CRUD permission:


 * Create: False
 * Read: True
 * Update: False
 * Delete: False

On the graph URI:


 * none

Here is the information needed to communicate with this Web service's endpoint. Descriptions of the parameters are included below.

Note: if a parameter has a default value, the requester can omit it and the default value will be used. Also, some baseline Web services may not offer other values than the default.

HTTP method:


 * POST

Possible "Accept:" HTTP header field value:


 * text/xml (structXML)
 * application/rdf+n3 (N3/Turtle)
 * application/iron+csv (commON)

URI:


 * http://[...]/ws/converter/common/?document=param1&docmime=param2&registered_ip=param3

URI dynamic parameters description:

Note: All parameters have to be URL-encoded


 * param1. Text of the document to convert
 * param2. The requested type of the conversion. One of:
 * "application/iron+csv (default)": Document formatted in commON
 * param3.Target IP address registered in the WSF. Needed when the IP of the requester is not the one of the one making the request to the endpoint. Otherwise this parameter as to be omitted.

Content Returned
The content returned by the Web service endpoint depends on the "Accept:" parameter sent by the requester. The converted content from the input document will be returned by using the requested serialization format.

HTTP Status Codes
Here are the possible HTTP status (error) codes returned by this Web service endpoint.

On error code and the specific error, a different message description can be issued (meaning a different error has been returned).

 * Message description:The target Web service (XYZ) needs update access and the requested user (XYZ) doesn't have this access for that dataset (XYZ)
 * Message description:The target Web service (XYZ) needs delete access and the requested user (XYZ) doesn't have this access for that dataset (XYZ)
