Overview of gCube Model Resources and (isRelatedTo) Relations

gCube Model Properties

GCubeProperty

GCubeProperty `extends` Property
Name	Type	Attributes	Description
Goal: Marker type for any properties extended in the gCube Model.
This type does not define any additional attributes.

The Java Interface declaration for such a type is available at:

https://code-repo.d4science.org/gCubeSystem/gcube-model/src/branch/master/src/main/java/org/gcube/resourcemanagement/model/reference/properties/GCubeProperty.java

ValueSchema

This type aims at exposing a value which can be automatically managed by any client with no knowledge of its format.

ValueSchema `extends` GCubeProperty
Name	Type	Attributes	Description
value	String	`Mandatory=true` `NotNull=true`	The value which schema is available at the URI provided in the schema property
schema	URI	`Mandatory=true` `NotNull=true`	An URI containing a schema used to validate/interpret the content of the value. It is only an informative field. The validation is charge of the client.

The client can retrieve the schema at the provided URI, i.e., schema property, and use its content to understand/validate/manipulate the information contained in the value property. The client must have the capability to understand the semantics of content retrieved at the URI endpoint. Examples of application of such type are eXtensible Markup Language (XML) values which can be validated by a Document Type Definition (DTD) or XML Schema Definition (XSD).

The Java Interface declaration for such a type is available at:

https://code-repo.d4science.org/gCubeSystem/gcube-model/src/branch/master/src/main/java/org/gcube/resourcemanagement/model/reference/properties/ValueSchema.java

AccessPolicy

AccessPolicy `extends` GCubeProperty
Name	Type	Attributes	Description
policy	Property (i.e. ValueSchema)
note	String

The Java Interface declaration for such a type is available at:

https://code-repo.d4science.org/gCubeSystem/gcube-model/src/branch/master/src/main/java/org/gcube/resourcemanagement/model/reference/properties/AccessPolicy.java

Facets

Access Point Facet

Access Point Facet `extends` Facet
Properties
Goal: This facet captures information on an 'access point' of a resource, i.e., any web-based endpoint to programmatically interact with the resource via a known protocol. For example, it is used to define the network endpoint to contact the service. The endpoint can expose a well-known high-level protocol. For example, it is used to define the network endpoint to contact the service. The endpoint can expose a well-known high-level protocol.
Name	Type	Attributes	Description
entryName	String		A distinguishing string to be used by clients to identify the access point of interest.
endpoint	URI	`Mandatory=true` `ReadOnly=true` `NotNull=true`	The URI which characterises the specific endpoint instance.
protocol	String		The high-level protocol used by the access point. The String could contain the version if needed. e.g., Web Map Service (WMS) and not HyperText Transfer Protocol (HTTP) which is already contained in the URI.
description	String		A human oriented text accompanying the access point.
authorization	Property		Contains authorisation information. e.g., a token, the couple username:password, etc.
Known Usage
Source	Relation	Multiplicity	Target	Description

Resources

Every Resource has:

An Header

Zero or More relation with other Resource

Extension Example

The gCube Resource Model supports extensions at runtime meaning that new facets, relations, and resources can be defined and registered at any time by authorized clients. Those extensions must necessarily specialize an existing gCube Entity. An example of those specializations is the following:

Functionality Related Facet

The goal of this facet is to capture what are the facilities supported by the Service Entity and it aims to model the service interface.

Functionality Related Facet `extends` Facet

output	String		...
Known Usage

To use the Java library containing the classes modelling the gCube Model you can declare the following dependency:
