Auth:Lister Web Service

Auth: Lister Web Service API Documentation

The Auth: Lister Web service is used to list all of the datasets accessible to a given user, list all of the datasets accessible to a given user with all of its CRUD permissions, to list all of the Web services registered to the WSF (Web Services Framework) and to list all of the CRUD permissions, for all users, for a given dataset created on a WSF.

This Web service is used to list all the things that are registered / authenticated in a Web Service Framework network.

Developers communicate with the Authentication: Lister Web service using the HTTP GET method. You may request one of the following mime types: (1) text/xml, (2) application/rdf+xml, (3) application/rdf+n3 or (4) application/json. The content returned by the Web service will be serialized using the mime type requested and the data returned will depend 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 all you 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

As shown on the graph URI:

  • http://[...]/wsf/

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:

  • GET

Possible "Accept:" HTTP header field value:

  • text/xml (DTD validating the returned content)
  • application/json
  • application/rdf+xml
  • application/rdf+n3

URI:

  • http://[...]/ws/auth/lister/ ?mode=param1&dataset=param2&registered_ip=param3

URI dynamic parameters description:

Note: All parameters have to be URL-encoded

  • param1 . One of:
    • "dataset (default)": List all datasets URI accessible by a user
    • "ws": List all Web services registered in a WSF
    • "access_dataset": List all the registered IP addresses and their CRUD permissions for a given dataset URI
    • "access_user": List all datasets URI and CRUD permissions accessible by a user
  • param2.URI referring to a target dataset. Needed when param1 = "dataset" or param1 = "access_datase". Otherwise this parameter as to be omitted.
  • param3.Target IP address registered in the WSF. Needed when param1 = "access_user". Otherwise this parameter as to be omitted.
