Facilitating construction of a user interface

A computer program product comprising a non-transitory computer-readable storage medium having computer-readable instructions stored thereon, the computer-readable instructions being executable by a computerized device to cause the computerized device to perform a method of facilitating construction of a user interface for policing input of user-defined data to a database, the method comprising:

• obtaining an ontology expressed in a first-order logic language, the ontology describing one or more predefined classes, a plurality of predefined properties and at least one predefined restriction;
• receiving data useable to identify a first class of the one or more predefined classes;
• in response to the receiving, generating, for the first class, an intermediate data structure configured to facilitate construction of the user interface for policing input of user-defined data to the database;
• and
• outputting the intermediate data structure to cause construction of the user interface,
• wherein generating the intermediate data structure comprises:
• identifying at least one property of the plurality of predefined properties from the ontology that is applicable to the first class;
• including the at least one property of the plurality of predefined properties from the ontology in the intermediate data structure;
• determining, for the at least one property, a property restriction function indicating whether the at least one predefined restriction from the ontology is applicable to the at least one property;
• and
• in response to the property restriction function indicating that the at least one predefined restriction is applicable to the at least one property, associating the at least one predefined restriction with the at least one property in the intermediate data structure.

An apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus at least to perform a method of facilitating construction of a user interface for policing input of user-defined data to a database, the method comprising:
• obtaining an ontology expressed in a first-order logic language, the ontology describing one or more predefined classes, a plurality of predefined properties and at least one predefined restriction;
• receiving data useable to identify a first class of the one or more predefined classes;
• in response to the receiving, generating, for the first class, an intermediate data structure configured to facilitate construction of the user interface for policing input of user-defined data to the database;
• and
• outputting the intermediate data structure to cause construction of the user interface,
• wherein generating the intermediate data structure comprises:
• identifying at least one property of the plurality of predefined properties from the ontology that is applicable to the first class;
• including the at least one property of the plurality of predefined properties from the ontology in the intermediate data structure;
• determining, for the at least one property, a property restriction function indicating whether the at least one predefined restriction from the ontology is applicable to the at least one property;
• and
• in response to the property restriction function indicating that the at least one predefined restriction is applicable to the at least one property, associating the at least one predefined restriction with the at least one property in the intermediate data structure.
