Key features

The core of the service is java based. It offers a interface for performing CRUD operation through a remote backend over JSON object:

• Create
• Read

Usage examples

To insert (create) a new record in the system, we might use:

• POST n039.smart-applications.area.pi.cnr.it:8080/storage/rest/resources?gcube-token=xxxxxxxx

To read a object with ID# 33245:

• GET http://n039.smart-applications.area.pi.cnr.it:8080/storage/rest/resources/33245?gcube-token=xxxxxxxx The same URI would be used for PUT and DELETE, to update and delete, respectively.

Here are proposed URIs for products:

• POST http://n039.smart-applications.area.pi.cnr.it:8080/storage/rest/resources?gcube-token=xxxxxxxx for creating a new object.

• GET|PUT|DELETE http://n039.smart-applications.area.pi.cnr.it:8080/storage/rest/resources/33245?gcube-token=xxxxxxxx

for reading, updating, deleting object with id 66432, respectively.

For deleting all the objects in the collection:

• DELETE http://n039.smart-applications.area.pi.cnr.it:8080/storage/rest/resources?gcube-token=xxxxxxxx
