Auth: Lister

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.

Version
This documentation page is used for the version 2 of this endpoint. Check at the top of this page to see the documentation pages for the other versions of this endpoint.

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 (structXML)
 * application/json (structJSON)
 * application/rdf+xml (RDF+XML)
 * application/rdf+n3 (N3/Turtle)
 * application/iron+json (irJSON)
 * application/iron+csv (commON)

URI:


 * http://[...]/ws/auth/lister/ ?mode=param1&dataset=param2&target_webservice=param3&registered_ip=param4&interface=param5

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 = "access_dataset". Otherwise this parameter as to be omitted.
 * param3. Determine on what web service URI(s) we should focus on for the listing of the access records. This parameter is used to improve the performance of the web service endpoint depending on the use case. If there are numerous datasets with a numerous number of access permissions defined for each of them, properly using this parameter can have a dramatic impact on the performances. This parameter should be used if the param1 = "access_dataset" or param1 = "access_user" This parameter can have any of these values:
 * "all" (default): all the web service endpoints URIs for each access records will be taken into account and returned to the user (may be more time consuming).
 * "none": no web service URI, for any access record, will be returned.
 * param4. Target IP address registered in the WSF. Needed when param1 = "access_user" asnd param1 = "dataset". Otherwise this parameter as to be omitted.
 * param5. Source interface used for this web service query. The interface is a different way to process a query (different algorithms, different data management system, etc. The default interface is 'default'

Available Sources Interfaces
A source interface is a way to process a web service query. Different sources interfaces can be implemented for the same structWSF web service endpoint. Each interface will process the query differently, but all the queries to the web service endpoint will be the same, at the exception of the  parameter. Each interface shares the same API (the one defined by the web service endpoint), but their processing may differ (like using different algorithms, using different data management systems, etc.)

This is a list of the core interfaces for this endpoint. Organizations that hosts a structWSF network could create their own interface and make it available to the users. However such private source interface won't be part of this list, but should be publicized by the organization.
