DATE: xsd:date, but no support for timezone. In this case, because timezone is not supported, all valid lexical representations are already canonical, so these can be treated like the OTHER case in the next item. RDF subjects and objects are mapped to nodes in the network data model. Subject nodes are the start nodes of links, and object nodes are the end nodes of links. Non-literal nodes that is, URIs and blank nodes can be used as both subject and object nodes.
Literals can be used only as object nodes. RDF triples may have unknown subject nodes and unknown object nodes. Blank nodes are used to represent these unknown nodes. Blank nodes are also used when the relationship between a subject node and an object node is n-ary as is the case with containers. A new entry is made for each blank node encountered in a triple. By default, no two blank nodes corresponding to two different objects will be mapped to the same network node; however, you can optionally reuse a specific blank node.
To reuse a blank node, you must use the blank node constructor described in Section 1. The blank node constructor is required for inserting containers see Section 1. RDF properties are mapped to links that have their start node and end node as RDF subjects and objects, respectively.
Therefore, a link represents a complete RDF triple. When a triple is inserted into an RDF model, the subject, property, and object text values are checked to see if they already exist in the database. Reification of an RDF statement is a means of providing metadata for that statement; it is the action that enables the statement to be used as the subject or object in another RDF statement.
Consider a plain English example in which the statement PersonA is a good job candidate is reified. Assume that the following statements are then made, using the reified statement as the object:. For PersonB and PersonC to be able to make such statements, a reification quad for the statement PersonA is a good job candidate must exist in the database, in a form such as the following:. Using the preceding example, the following query:.
In the current release, you cannot reify statements. However, if your data includes reified statements, the RDF model stores the reification quads. A container is a resource that contains things. The contained things are called members. The members of a container may be resources including blank nodes or literals.
A Bag a resource having type rdf:Bag represents a group of resources or literals, possibly including duplicate members, where there is no significance in the order of the members. A Sequence or Seq a resource having type rdf:Seq represents a group of resources or literals, possibly including duplicate members, where the order of the members is significant.
An Alternative or Alt a resource having type rdf:Alt represents a group of resources or literals that are alternatives typically for a single value of a property. For example, an Alt might be used to describe alternative language translations for the title of a book, or to describe a list of alternative Internet sites at which a resource might be found.
An application using a property whose value is an Alt container should be aware that it can choose any one of the members of the group as appropriate. In the Oracle RDF data model, containers follow the general rules for triple insertion. As with other triples, the containerValue object will be reused if this node already exists in the database.
In the Oracle RDF data model, collections are handled similarly to containers, except an additional constraint is enforced. As with other triples, the listValue object will be reused if this node already exists in the database. Because collections are closed, a constraint is enforced such that no new members can be added to the list.
A rule is an object that can be applied to draw inferences from RDF data. A rule is identified by a name and consists of:. For example, the rule that a chairperson of a conference is also a reviewer of the conference could be represented as follows:. In this case, the rule does not have a filter condition, so that component of the representation is NULL. A rulebase is an object that contains rules.
Two Oracle-supplied rulebases are provided:. User-defined rulebases enable you to provide additional specialized inferencing capabilities. For each rulebase, a system table is created to hold rules in the rulebase, along with a system view with a name in the format MDSYS. You must use this view to insert, delete, and modify rules in the rulebase. Filter condition that further restricts the subgraphs matched by the IF side pattern. Null indicates no filter condition is to be applied.
One or more namespaces to be used. Name of the view that you must use for any SQL statements that insert, delete, or modify rules in the rulebase. This rule says that if a person is the parent of a child who is the parent of a child, that person is a grandparent of that is, has the grandParentOf relationship with respect to his or her child's child. It also specifies a namespace to be used.
This example is an excerpt from Example in Section 1. A rules index is an object containing precomputed triples that can be inferred from applying a specified set of rulebases to a specified set of models. Name of the view that you must use for any SQL statements that insert, delete, or modify rules in the rules index.
Information about all database objects, such as models and rulebases, related to rules indexes is maintained in the MDSYS. This view has the columns shown in Table and one row for each unique combination of values of all the columns. To perform data manipulation language DML operations on a model, a user must have DML privileges for the corresponding base table.
To perform data manipulation language DML operations on a rulebase, a user must have the appropriate privileges on the corresponding database view.
Table lists the tables and views in alphabetical order. In addition, several tables and views are created for Oracle internal use, and these are accessible only by users with DBA privileges.
