Basic Concepts

  • Two typologies of entities are envisaged:
    • Resources, i.e. entities representing a description of "thing" to be managed;
      • Every Resource is characterised by a number of Facets.
    • Facets, i.e. entities contributing to "build" a description of a Resource. Every facet, once attached to a Resource profile captures a certain aspect / characterization of the resource;
      • Every facet is characterised by a number of properties;
  • Entities and relations can be specialized.
    • A number of specializations are identified below. Such specializations are managed by the gCube Core services, i.e. Core services builds upon these specialization to realize its management tasks;
    • Other specializations can be defined by clients, the system make it possible to store these additional typologies of relations and facets and to discover them.
  • On relations:
    • Any relation has a direction, i.e. a "source" (out bound of the relation) and a "target" (in bound of the relation). Anyway the relation can be also navigated in the opposite direction;
    • It is not permitted to define a Relation having a Facet as "source". In other words:
      • It is not permitted to define a Relation connecting a Facet with another one;
      • It is not permitted to define a Relation connecting a Facet with a Resource (as target);
    • A Facet instance can be linked (by consistsOf or any specialization of it) from different Resources.

Property

Any Property can be enriched with the following attributes:

  • Name : Property Name
  • Type : The Type of the Property (e.g. String, Integer, ...). See Property Type
  • Description : The description of the Property. default=null.
  • Mandatory (M): Indicate if the Property is mandatory. default=false.
  • ReadOnly (RO): The Property cannot change its value. default=false.
  • NotNull (NN): default=false
  • Max (Max): default=null
  • Min (Min): default=null
  • Regexpr (Reg)): A Regular Expression to validate the property value.default=null

Property Type

Basic Property Type
Type Description Java type
Boolean Handles only the values True or False java.lang.Boolean or boolean
Integer 32-bit signed Integers java.lang.Integer or int
Short Small 16-bit signed integers java.lang.Short or short
Long Big 64-bit signed integers java.lang.Long or long
Float Decimal numbers java.lang.Float or float
Double Decimal numbers with high precision java.lang.Double or double
Datetime Any date with the precision up to milliseconds. java.util.Date
String Any string as alphanumeric sequence of chars java.lang.String
Embedded This is an Object contained inside the owner Entity and has no Header. It is reachable only by navigating the owner Entity. org.gcube.informationsystem.model.embedded.Embedded
Embedded list List of Objects contained inside the owner Entity and have no Header. They are reachable only by navigating the owner Entity. List<? extends Embedded>
Embedded set Set (no duplicates) of Objects contained inside the owner Entity and have no Header. They are reachable only by navigating the owner Entity. Set<? extends Embedded>
Embedded map Map of Objects contained inside the owner Entity and have no Header. They are reachable only by navigating the owner Entity. Map<String, ? extends Embedded>
Link ... Link to another Entity. ...
Byte Single byte. usesful to store small 8-bit signed integers java.lang.Byte or byte
Binary Can contain any value as byte array java.lang.Byte[] or byte[]
Any Not determinated type, used to specify Collections of mixed type, and null java.lang.Object
Derived Property Type

The following are obtained using a String as real type and adding a validation regex.

Type Description Java type
Enum by default it is represented using the String representation of the Enum. So that the primitive type used will be String. The enumeration is checked by setting Regexpr property. The Regular Expression is auto-generated and it will be something like (FIRST-ENUM-STRING_REPRESENTATION|SECOND-ENUM-STRING_REPRESENTATION|...|LAST_ENUM_STRING_REPRESENTATION).

Otherwise (if indicated using an annotation), it can be represented using the Integer value of the Enum. So that the primitive type used will be Integer. The enumeration is checked using Max and Min properties.

java.lang.Enum or enum
UUID String representation of the UUID. The check is obtained using the regular expression ([a-fA-F0-9]{8}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{12}){1} java.util.UUID
URL String representation of the URL. The check is obtained using a regex available at https://mathiasbynens.be/demo/url-regex (see diegoperini one). java.net.URL
URI String representation of the URI. The check is obtained using . java.net.URI

Header

Every Entity and Relation has an Header automatically filled by the System. The Header has the following properties:

Name Type Description Attributes
uuid UUID This uuid can be used to univocally identify the Entity or the Relation Mandatory=true NotNull=true ReadOnly=true
creator String Filled at creation time. The creator is retrieved using the authorization token Mandatory=true NotNull=true ReadOnly=true
creationTime Datetime Creation time in milliseconds. Represent the difference, measured in milliseconds, between the creation time and midnight, January 1, 1970 UTC Mandatory=true NotNull=true ReadOnly=true
lastUpdateTime Datetime Last Update time in milliseconds. Represent the difference, measured in milliseconds, between the last update time and midnight, January 1, 1970 UTC Mandatory=true NotNull=true


Resources and (isRelatedTo) Relations

Facets

Early ideas and thinking on facets were documented at 2nd Generation Resource Model : Facets

Facet

Every Facet has:

Access Point Facet

The goal of this facet is expected to capture information on “access points” for a resource, i.e. any endpoint to interact with the resource via a known protocol.

Facet Access Point Facet
Name Type Description Attributes
entryName String An unique identifier
endpoint URI The URI which identify the endpoint of a resource Mandatory=true ReadOnly=true NotNull=true
protocol String The high-level protocol used by the access point. The String could contains the version if needed.

E.g. WMS not http which is already contained in URI.

description String .....
authorization String Contains authorization information. E.g: a token, username:password. By relying on schema it should be sufficient to capture also whether the content is encrypted or not
authorizationSchema URI ....
properties String This can be an arbitrarily complex element whose "structure" is defined by the associated schema
propertiesSchema URI ....

Best practices and guidelines

  • On Facet instances "reuse" across Resource Profiles:
    • This can be guaranteed automatically by the system, if and just in the case the system want to avoid duplication of information. It is based on a configuration policy;
    • This MUST be done only when a change in a facet instance MUST affect a change in all Resources connected to such a Facet.

Internal Entity and Relation

For internal use only are defined the following entity and relation:
