The Dataset: Create Web service is used to create a new dataset in a WSF (Web Services Framework). When a dataset is created, it gets described and registered to the WSF and accessible to the other Web services.

Developers communicate with the Dataset: Create 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 1.1 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: True
  • Read: False
  • Update: False
  • 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://[...]/wsf/dataset/create/ ?uri=param1&title=param2&description=param3&creator=param4&webservices=param5&globalPermissions=param6

URI dynamic parameters description:

Note: All parameters have to be URL-encoded

  • param1. URI to refer to this new dataset
  • param2. Title of the dataset to create
  • param3. Description of the dataset to create
  • param4. Unique identifier used to refer to the creator of this dataset
  • param5. Web services that can be used to access and manage that dataset. It is list of ";" separated Web services URI
  • param6. Default global permissions for this dataset. False;False;False;False by default (so, no global permissions defined)

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.
