Revision: Lister

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 endpoint is used to list all the revisions existing for a record. All the revision records have a unix timestamp in microseconds. This timestamp is defined as a. All the revisions records can be sorted using this timestamp. If a user want to see what was the description of a record at a specific time, then he will use the  web service endpoint to get all the triple of that record, for that revision.

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/revision/lister/ ?uri=&dataset=&mode=&interface=&version=

URI dynamic parameters description:

Note: All parameters have to be URL-encoded


 * uri. URI of the record for which you want the revisions
 * dataset. Dataset URI where to index the RDF document. Note: this is the Dataset URI, and not the Dataset Revisions URI
 * mode. Verbosity of the records to return with this endpoint. One of:
 * short — Get the list of all the URIs of all the revisions for that record and their date stamp (for ordering purposes)
 * long (default) — Get the list of all the URIs, revision performer, their lifecycle stage and their date stamp (for ordering purposes) for that record
 * 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. Version of the source interface that is compatible with this query. If this parameter is omitted, then the latest version of the source interface is used for this 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  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.

Example of Returned XML Document
This is an example of the XML document returned by this Web service endpoint for a given URI. This example returns a list of datasets accessible by a given user IP.

Query:


 * http://[...]/ws/revision/lister/?mode=long&dataset=http://localhost/datasets/hin/documents/local/&uri=http://crud_update_test_2"

"Accept:" HTTP header field value:


 * text/xml

On error code and the specific error, a different message description can be issued (meaning a different error has been returned).
