The CRUD: Delete Web service is used to delete an existing instance record indexed in some target dataset of an OSF Web Services instance. When the instance record gets deleted, it gets deleted from the dataset. You may choose either to retain all prior revisions of that record or perform a complete delete that removes all revision records.

Developers communicate with the CRUD: Delete Web service using the HTTP GET method. You may request any of the available content types (*/*).

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 3 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 a WSF (Web Service Framework) resource (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: False
  • Delete: True

As shown on the graph URI:

  • URI of the dataset where the instance record is indexed

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:

  • */*

URI:

  • http://[...]/ws/crud/delete/?uri=&dataset=&mode=&interface=&version=

URI dynamic parameters description:

Note: All parameters have to be URL-encoded

  • uri. URI of the instance record to delete
  • dataset. URI of the dataset where the instance record is indexed
  • mode. Specify if you want to keep all revision records, or delete all of them. One of:
    • soft (default) - Delete the record, but keep all its revisions. This act like unpublishing the record. If you use this mode, you will always be able to re-publish the record using the Revision: Update web service endpoint
    • hard - Delete all the revision records of the record. If you use this mode, you won't be able to re-create this record in the future, it will be deleted from all the systems and will be vanished
  • interface. 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'
  • version. (default: 3.0) Version of the interface to query

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 interface 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.


Source Interface Name Description
default Default source interface for this OSF Web Service endpoint. This interface implements the default behavior of this OSF Web Service endpoint.

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
