Archive 2.x:Dataset: Update/2

The Dataset: Update Web service is used to update the description of an existing dataset in a WSF (Web Services Framework).

Developers communicate with the Dataset: Update Web service using the HTTP POST method. You may request any content type (*/*). '''No content is returned by the Web service endpoint if the endpoint successfully executed the query. Only a "200 OK" message will be returned in the header.'''

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: False
 * Update: True
 * Delete: False

As shown on the graph URI:


 * http://[...]/wsf/dataset/

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:



URI:


 * http://[...]/ws/dataset/update/ ?uri=param1&title=param2&description=param3&contributors=param4& modified=param5&interface=param6

URI dynamic parameters description:

Note: All parameters have to be URL-encoded

Note 2: If param2, param3, param4 or param5 are defined in the HTTP query but that doesn't have any value, this tells the Web service to REMOVE the propery. For example, if the query defines the param2 such as "&title=&", this will tell the Web service to remove the title in the description of the dataset.


 * param1. Unique identifier used to refer to the dataset to update
 * param2. (optional)''. Title of the dataset to update
 * param3. (optional)''. Description of the dataset to update
 * param4. (optional)''. List of contributor URIs seperated by ";"
 * param5. (optional)''. Date of the modification of the dataset
 * param6. 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 OSF 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 OSF Web Service 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.

Query Answer from the Endpoint
If the query is successfully performed by the endpoint (i.e., the Web service resource has been properly created, updated or deleted), the endpoint will return the HTTP status message "200 OK" with an empty body. If an error occured, one of the HTTP status messages with the description of the error message in the body of the HTTP query will be returned.

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).


 * Code: 200
 * Message: OK


 * Code: 400
 * Message: Bad Request
 * Message description: This dataset doesn't exist in this WSF
 * Message description: No unique identifier specified for this dataset
 * Message description: No target dataset
 * Message description: No Web service URI available
 * Message description: Target Web service XYZ not registered to this Web Services Framework
 * Message description: No access defined for this requester IP XYZ, dataset (XYZ) and Web service (XYZ)
 * Message description: The target Web service (XYZ) needs create access and the requested user (XYZ) doesn't have this access for that dataset (XYZ)
 * Message description: The target Web service (XYZ) needs read access and the requested user (XYZ) doesn't have this access for that dataset (XYZ)
 * 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)


 * Code: 406
 * Message: Not Acceptable
 * Message description: Unacceptable mime type requested
