−
Security configuration based on [[Authorization Framework]] make this port type accessible only from [[Information System Resource Manager|Resource Manager]]. In other words no others client is allowed to manage [[Facet_Based_Resource_Model#Context| Context]] rather than [[Information System Resource Manager|Resource Manager]].

Available Methods:
+
Any request to this port type has success if the following guarantees are satisfied:
  
−
* [[#Create|Create]]
+
* the hierarchy of contexts is a tree with an arbitrary number of levels;
−
* [[#Read|Read]]
+
* two contexts with the same name can only exist if they have different parents;
−
* [[#Rename|Rename]]
+
* any update to a context does not have any side effect on the instances belonging to the context;
−
* [[#Move|Move]]
+
* it is not possible to delete a context if
−
* [[#Delete|Delete]]
+
** it contains instances. It is the responsibility of the clients to remove the instances from the context (or delete them) before trying to delete the context;
 +
** it has children context. It is the responsibility of the clients to remove or move the children context before trying to delete the context.
  
−
Any action made to Contexts succeed if the following requirements are guaranteed:
 
−
* Two Context with same name can exist but only if they have different parents. The operation which will try to obtain a Context with the same name to the same parent will fails with no effect.
 
−
* Any operation made in any Context has effect only to the Context. In other words, there will be no effect on the associated Entity and Relations.
 
  
−
At time of writing this port type is only accessible by using REST API. [[Information System Resource Registry#Resource_Registry_Context_Client | Resource Registry Context Client]] (java client) is under development.
+
Context Management exposes the following APIs:
  
−
=== Create ===
+
* '''[[#List Contexts|List]]''': allows to enumerate the contexts;
 +
* '''[[#Create Context|Create]]''': allows to create a new context as a child of another context (if any). The context has a name;
 +
* '''[[#Exists|Exists]]''': allows to check if a Context exists;
 +
* '''[[#Read Context|Read]]''': allows to read a Context;
 +
* '''[[#Update Context|Update]]''':
 +
** '''[[#Rename Context|Rename]]''': rename a context;
 +
** '''[[#Move Context|Move]]''': move a context as a child of another Context.
 +
* '''[[#Delete Context|Delete]]''': allows to delete a Context.

==== Example 1 ====
+
Security configuration based on [[Authorization Framework]] make this port type accessible only from [[Information System Resource Manager|Resource Manager]]. In other words, no others client is allowed to manage [[Facet_Based_Resource_Model#Context| Context]] rather than [[Information System Resource Manager|Resource Manager]].
  
−
Create a new Context with name '''gcube''' with no parent. It is a ROOT Context.
+
== Resource Registry Context Client ==
  
−
''Request URL''
+
Resource Registry Context Client is a java library providing RPC facilities to interact with [[#Context Collection|Context Collection]].
 +
The library hides all the complexity of marshalling and unmarshalling of requests and results.
 +
By using this library any client is able to manage java classes instead of JSON objects.
  
−
<pre>PUT /resource-registry/context?name=gcube</pre>
+
To use the Java library to interact with Context Collection declare the following dependency in your pom.xml file.
  
−

These sections provide information regarding how to interact with Resource Registry Service for Context Management. REST API are presented for each functionality.

Please note that the provided examples can intentionally hide some details in the response to avoid unneeded complexity.

Context Management

Context Management is responsible for managing hierarchical Context as defined by the IS Model.

Context requirements:

  • No predefined number of levels;
  • Possibility to change the name of the Context with no impact for any component;
  • Possibility to move a Context from a parent Context to another.

Any request to this port type has success if the following guarantees are satisfied:

  • the hierarchy of contexts is a tree with an arbitrary number of levels;
  • two contexts with the same name can only exist if they have different parents;
  • any update to a context does not have any side effect on the instances belonging to the context;
  • it is not possible to delete a context if
    • it contains instances. It is the responsibility of the clients to remove the instances from the context (or delete them) before trying to delete the context;
    • it has children context. It is the responsibility of the clients to remove or move the children context before trying to delete the context.


Context Management exposes the following APIs:

  • List: allows to enumerate the contexts;
  • Create: allows to create a new context as a child of another context (if any). The context has a name;
  • Exists: allows to check if a Context exists;
  • Read: allows to read a Context;
  • Update:
    • Rename: rename a context;
    • Move: move a context as a child of another Context.
  • Delete: allows to delete a Context.

Context Collection

The following table shows the exposed APIs as REST Collection

Operation HTTP Method URL
List GET /contexts
Create PUT /contexts/{UUID}
Exists HEAD /contexts/{UUID}
Read GET /contexts/{UUID}
Update PUT /contexts/{UUID}
Delete DELETE /contexts/{UUID}

Security configuration based on Authorization Framework make this port type accessible only from Resource Manager. In other words, no others client is allowed to manage Context rather than Resource Manager.

Resource Registry Context Client

Resource Registry Context Client is a java library providing RPC facilities to interact with Context Collection. The library hides all the complexity of marshalling and unmarshalling of requests and results. By using this library any client is able to manage java classes instead of JSON objects.

To use the Java library to interact with Context Collection declare the following dependency in your pom.xml file. 

<dependency>
	<groupId>org.gcube.information-system</groupId>
	<artifactId>resource-registry-context-client</artifactId>
	<version>[4.0.0,5.0.0-SNAPSHOT)</version>
<dependency>


To use the client you just need to instantiate the client via the provided factory. 

import org.gcube.informationsystem.resourceregistry.context.ResourceRegistryContextClient;
import org.gcube.informationsystem.resourceregistry.context.ResourceRegistryContextClientFactory;
 
....
 
ResourceRegistryContextClient resourceRegistryContextClient = ResourceRegistryContextClientFactory.create();

The provided client exposes the available methods and options as explained below.

The source code of the resource-registry-context-client is available at https://code-repo.d4science.org/gCubeSystem/resource-registry-context-client

APIs

The provided examples are based on the following Context tree 

-  ca50eb95-b76c-44fd-9182-229d39c3c9e2 (gcube)
|
|---- d0544ff9-8f61-416f-b685-589a2262e2c4 (devsec)

Move Context

We have 5 Contexts organized in the following Context Tree: 

-  ca50eb95-b76c-44fd-9182-229d39c3c9e2 (gcube)
|
|---- d0544ff9-8f61-416f-b685-589a2262e2c4 (devsec)
|   |
|   |---- 4c0c3500-32d6-11ea-867c-af3c989f8e41 (devVRE)
|
|---- aa860961-6eb0-4c1c-89fb-c406fe2a2771 (devNext)
    |
    |---- bad5f350-345c-11e9-9f49-cef9b1608c3f (NextNext)

We want to move Context bad5f350-345c-11e9-9f49-cef9b1608c3f (NextNext) as child of the Context ca50eb95-b76c-44fd-9182-229d39c3c9e2 (gcube) in palce of aa860961-6eb0-4c1c-89fb-c406fe2a2771 (devNext) In other words, NextNext will be a VO in place of a VRE.

We will obtain the following Context tree 

-  ca50eb95-b76c-44fd-9182-229d39c3c9e2 (gcube)
|
|---- d0544ff9-8f61-416f-b685-589a2262e2c4 (devsec)
|   |
|   |---- 4c0c3500-32d6-11ea-867c-af3c989f8e41 (devVRE)
|
|---- aa860961-6eb0-4c1c-89fb-c406fe2a2771 (devNext)
|
|---- bad5f350-345c-11e9-9f49-cef9b1608c3f (NextNext)

Delete Context

Delete the Context identified by the UUID provided as the path parameter.

The resource registry performs the following checks before deleting a context:

  • the context MUST have no children: this implies that you can't delete the testVO context if you don't have deleted (or moved to another parent) the context testVRE;
  • the context MUST NOT have associated entities and relation instances: this implies that the client must remove in advance the available instances from the context.

Delete via Java Client

Delete using UUID. This normally used when we already have the UUID instance. 

ResourceRegistryContextClient resourceRegistryContextClient = ResourceRegistryContextClientFactory.create();
resourceRegistryContextClient.delete("bad5f350-345c-11e9-9f49-cef9b1608c3f");

Delete using context instance. This normally used when we already have the context instance. 

ResourceRegistryContextClient resourceRegistryContextClient = ResourceRegistryContextClientFactory.create();
Context nextNextContext = resourceRegistryContextClient.read("bad5f350-345c-11e9-9f49-cef9b1608c3f");
resourceRegistryContextClient.delete(nextNextContext);

Delete via REST API
