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

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

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.

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.


It exposes the common functionalities of any collection as recommended by ROA such as:

  • 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 HTTP APIs for contexts 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}

Resource Registry Context Client

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>

Create With Java Client

This Java code snippet shows how to create contexts used in examples 1 and 2. 


ResourceRegistryContextClient resourceRegistryContextClient = ResourceRegistryContextClientFactory.create();
 
Context gcubeContext = new ContextImpl("gcube");
// Java class generate a random UUID and use to interact with Resource Regsitry Service
// To specify the UUID 
// UUID gcubeUUID = UUID.fromString("ca50eb95-b76c-44fd-9182-229d39c3c9e2");
// Context gcubeContext = new ContextImpl("gcube", gcubeUUID);
gcubeContext = resourceRegistryContextClient.create(gcubeContext);
 
 
Context devNextContext = new ContextImpl("devNext");
// To specify the UUID 
// UUID devNextUUID = UUID.fromString("aa860961-6eb0-4c1c-89fb-c406fe2a2771");
// Context testVOContext = new ContextImpl("devNext", devNextUUID);
devNextContext.setParent(gcubeContext);
devNextContext = resourceRegistryContextClient.create(devNextContext);

Read Context

Read With Java Client

Read using a string representing the UUID. 

ResourceRegistryContextClient resourceRegistryContextClient = ResourceRegistryContextClientFactory.create();
Context gcubeContext = resourceRegistryContextClient.read("ca50eb95-b76c-44fd-9182-229d39c3c9e2");


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

ResourceRegistryContextClient resourceRegistryContextClient = ResourceRegistryContextClientFactory.create();
UUID devNextUUID = UUID.fromString("aa860961-6eb0-4c1c-89fb-c406fe2a2771");
Context devNextContext = resourceRegistryContextClient.read(devNextUUID);


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

UUID devNextUUID = UUID.fromString("aa860961-6eb0-4c1c-89fb-c406fe2a2771");
Context devNextContext = new ContextImpl("devNext", devNextUUID);
ResourceRegistryContextClient resourceRegistryContextClient = ResourceRegistryContextClientFactory.create();
devNextContext = resourceRegistryContextClient.read(devNextContext);

Update Context

PUT /resource-registry/contexts/{UUID}

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)

If we read the Context bad5f350-345c-11e9-9f49-cef9b1608c3f' (NextNext) before moving it we have:

Delete Context

DELETE /resource-registry/contexts/{{UUID}}


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


For example to delete the Context having UUID bad5f350-345c-11e9-9f49-cef9b1608c3f (NextNext) we just need to perform the following HTTP request 

DELETE /resource-registry/contexts/bad5f350-345c-11e9-9f49-cef9b1608c3f

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.
