Attribute

@Entity

class Attribute(var dataID: Long? = null, var uri: String = "", var name: String = "", var dType: String = "", var node: Node? = null)

The Attribute represents the model element typically known as attribute or property. By default, only Nodes can have Attributes. An Attribute consists of identifiers and a key-datatype pair expressing the physical attribute model.

Constructors

constructor()

constructor(dataID: Long? = null, uri: String = "", name: String = "", dType: String = "", node: Node? = null)

Properties

dataID

var dataID: Long?

Technical database (JPA) identifier used for relation joins. The dataID is system specific and not exported to XML. It must not be used to identify elements in distributed use-cases. It should not be used to identify elements from outside the service. All model elements provide other suitable identifiers to be used.

dType

var dType: String

The data type of the attribute serialized as string. TODO: right now, arbitrary types are supported. A later type checker must predefine a set of type values.

name

var name: String

The name of an Attribute, also called key. Uniqueness is optional but should be enforced on the level of a single Node.

node

var node: Node?

Backlink to Model to improve traversal.

uri

var uri: String

The unique naming URI of the Attribute in its current Model. The uri must not take variant/version into account which is stored separately. A modicio URI is defined as a "xs:anyURI" base with the schema extension "modicio:.*"
