Axiomatization

Classes

Consumer

Forced Binding

IRI: https://onto.vaimee.com/pac#ForcedBinding

Represents a forced variable binding used in a SPARQL operation within a PAC.

Sub-class of	`Sparql Fragment`
Super-class of	`Literal Forced Binding` `Uri Forced Binding`

Literal Forced Binding

IRI: https://onto.vaimee.com/pac#LiteralForcedBinding

A forced binding whose value is a literal.

Sub-class of	`Forced Binding`
In the domain of	`data type` `default value`

Namespace

IRI: https://onto.vaimee.com/pac#Namespace

Represents an RDF namespace. They allow grouping related terms (classes and properties) under a common base URI.

In the domain of	`prefix`
In the range of	`has namespace`

Operation

IRI: https://onto.vaimee.com/pac#Operation

An abstract superclass representing any operation described in a PAC.

Super-class of	`Rule` `Sparql Operation`
In the domain of	`has forced binding` `is operation of` `sparql` `uses snippet`
In the range of	`includes operation`

Pac

IRI: https://onto.vaimee.com/pac#Pac

Defines a PAC (JSON SPARQL Application Profile). PAC describes an application based on the SPARQL Event Processing Architecture (SEPA) and following the application design pattern named PAC (Producer-Aggregator-Consumer).

In the domain of	`has component` `has namespace` `includes operation`
In the range of	`is operation of`

Pac Component

IRI: https://onto.vaimee.com/pac#PacComponent

A component in a PAC application following the PAC (Producer-Aggregator-Consumer) architectural pattern.

Super-class of	`https://onto.vaimee.com/pac#Aggregator` `Consumer` `Producer`
In the domain of	`performs query` `performs subscription` `performs update`
In the range of	`has component`

Producer

IRI: https://onto.vaimee.com/pac#Producer

A component of the PAC architecture that makes exactly one SPARQL update and no subscription.

Sub-class of	`Pac Component`
Enumeration members

Query

IRI: https://onto.vaimee.com/pac#Query

A SPARQL operation that retrieves information from a knowledge base without modifying it. Examples include SELECT, ASK, and CONSTRUCT queries.

Sub-class of	`Sparql Operation`
In the range of	`performs query` `performs subscription`

Rule

IRI: https://onto.vaimee.com/pac#Rule

A general-purpose rule defined within a PAC configuration. A rule can express declarative logic or behavior that triggers specific operations (e.g., updates) under certain conditions.

Sub-class of Operation

Snippet

IRI: https://onto.vaimee.com/pac#Snippet

Represents a reusable SPARQL code fragment that can be included in one or more operations.

Sub-class of	`Sparql Fragment`
In the domain of	`snippet body`
In the range of	`uses snippet`

Sparql Fragment

IRI: https://onto.vaimee.com/pac#SparqlFragment

Defines a fragment of SPARQL that can be inserted into queries or updates, typically through variable substitution or templating mechanisms.

Super-class of Forced Binding
Snippet

Sparql Operation

IRI: https://onto.vaimee.com/pac#SparqlOperation

Abstract superclass for SPARQL-based operations. It encompasses both queries and updates that interact with the RDF knowledge base using SPARQL 1.1 syntax.

Sub-class of	`Operation`
Super-class of	`Query` `Update`

Update

IRI: https://onto.vaimee.com/pac#Update

A SPARQL operation that modifies the knowledge base by inserting, deleting, or updating triples. Examples include INSERT DATA, DELETE DATA, and DELETE/INSERT operations.

Sub-class of	`Sparql Operation`
In the range of	`performs update`

Uri Forced Binding

IRI: https://onto.vaimee.com/pac#UriForcedBinding

A forced binding whose value is a URI.

Sub-class of	`Forced Binding`
In the domain of	`default value`
