Instances of this ontology are combined with other domain ontologies to generate graphical user interfaces to populate ontology instances (knowledge graphs).

Ontology for Ontology-based Ontology Population V 0.1, Release 2021-01-01 This object property specifies that an action manipulates data in the referenced block. For example, an instance of SubmitBlockAction is associated with a block (form) and represents the form's submit function. activatesAction An interface element activates a branching statement which is used to deside what option should be chosen. The belongsTo property relates visual element or other elements to different entities, e.g., to blocks that represent HTML forms. belongsTo A belongsToCollection is an object property that relates a collection item and collection that collection item belongs to. belongsToCollection The belongsTo property relates a visual element to an interface container it belongs to. belongsToVisual This property relates a Connection element to an individual representing the source of an ObjectProperty. That would be the subject of the ObjectProperty created during runtime. connectionHasSource The connectionHasTarget property relates a Connection element to an individual which is an object of an ObjectProperty. connectionHasTarget The containsDatatype relates a field to a DataProperty which should be inserted into the field. In this way, the domain ontology is related to the graphical user interface contains datatype An Action is directly executed when the control flow reaches it. In contrast to the activatesAction property, this property is used to specify that the action is immediately performed when this property is reached in the control flow. executesAction generated from the model hasBranching hasCondition The hasConnection relates an Action element to a Connection element that will be established between two instances in runtime. hasConnection Each connector specifies an object property that links two instances in a knowledge graph. A single connection may consist of multiple connectors and that is presented with this property". hasConnector The property contains values that can be chosen in graphical control elements such as drop down lists or multiple choice lists. hasFieldValues hasLoop hasSequence testing This object property points to the left side of the dependecy statement. This is especially useful for expressing rdfs:subClassOf inference rules as this represents the left side of rdfs:subClassOf This object property points to the target side of the dependecy statement. This is especially useful for expressing rdfs:subClassOf inference rules as this represents the object of rdfs:subClassOf inference rule. hasTargetOfDependency false This object property relates a Visual element to a concrete individual of the corresponding target ontology. related to named individual true model belongs to interface container This object property specifies that an element has further specification in another element. For example, it is used to connect a property in a SHACL shape to a Field instance that contains a further description of the form element. specifiedBy This object property corresponds to the SHACL.targetClass property and it is related to the block. It specifies the type of instance that is generated when the form is submited. All other block (form) elements are often used to define data properties of this instance. The property specifies that a given element (e.g., a named individual) belongs to the model part (implant that consists of named individuals belonging to the domain ontologies). belongsToModel This property indicates whether only the first variable is taken from the result of the SPARQLQuery. extractFirstOnlyVariable This property is used to specify the last (final value) in a loop. finalValue This property specifies the activity (attribute) in the HTML element that initiates the corresponding action. This is for example "onclick" attribute of the HTML button element. The values are textual names for these attributes in camel case, e.g., "onClick". There can be more values for the same action. This property specifies the label of a visual element that has to stand next to that element. This could be a label next to the input field on a HTML form. hasLabel This property specifies the position of an element on a HTML form. This is an integer number that represents the ordinary position among all other elements in the corresponding form looking from the upper left corner. hasPosition The visible text displayed by an element in the user interface. For example, a label has a text that has to be presented in the UI element. has text The hasValue data property relates an instance to a data assigned to that instance. One example is a Condition class. The Default data property specifes whether the corresponding property is the default property. For instance a default value of a drop down list. isDefault This object property specifies what is the purpose of this model. If the model is used for an conversational agent then this explanation could be used to describe to the user what is the goal of this model. According to this description the user can choose a suitable model. The property assignes a number to the model part specifying the version of the current interface. This can be used to track the version of the interface used to populate the knowledge graph. hasModelNumber This datatype property holds the textual content of a SPARQL query in text form. It is a well-formulated SPARQL query in a string literal. sparqlText The specifiesEndOfIRI data property value "true" tells us that the string entered by the corresponding element will be used to form end of the IRI in the instance that will be generated. specifiesIRI An action represents an activity on the form. It could be a simple saving of data on the form and switching control flow to the next HTML form. Action Block Branching Button This action type corresponds to the cancel button Collection A collection item could be a complex element that consists of a name that is visible to the user (or is writen in chatbots) and a value which could be a named individual. CollectionItem Condition 1 1 This class describes the way in which two instances are related with object properties. Connection This class represents connectors that specify further how two instances are connected. If the two instancess are represented by SHACL shapes for example, then each connector corresponds to a shacl:property that defines a shacl:path. Connection elements have one or more connectors because each connecton can contain more object properties that connect two instances defined by SHACL shapes. Connector A conversation block represents a collection of data entered in a single turn using a conversational agent. It servers as a modeling component for a part of the chatbot dialog which is analogous to HTML forms in web applications. ConversationBlock Field Functional Container This action generates a JSONForm representation for an HTML form, derived from a SHACL shape and additional Block elements. HorizontalLayout This class serves the need of expressing inference rules such as RDFS and OWL inference rules. InferenceDependency Label List value Loop LoopCondition This action is reserved for making connections between elements entered by many blocks (forms). The model describes the interface model for population of domain ontologies. A model can be specification of web interface, chatbot, etc. The action considers more blocks or has an influence on more blocks, (e.g., data described with more SHACL shapes) This class represents questions posed in chatbots Question The action performs a validation of the entered knowledge graph to ensure it conforms to the SHACL shapes. This class is used to represent a SPARQL query executed over an output RDF graph. Since the result of such a query is also a graph (or a set of RDF triples), this class includes properties that specify which parts of the resulting data can be extracted and utilized. For example, it can be used to retrieve a list of relevant nodes or resources from the query results, enabling targeted access to specific portions of the data graph. One example is the property obop:extractFirstOnlyVariable. SPARQLQuery A single value request corresponds to a question to insert a value in a chatbot. 1 1 This class is used to express rdfs:subClassOf inference rule in interface models. SubClassOfDependency A part of the model that consists of more nodes and edges. Subgraph This action corresponds to the submit button. VerticalLayout VisualElement
