Extensibility application programming interface and framework for meta-model objects
View Patent ↗The present invention relates to a system and methodology providing an Application Programming Interface (API) and framework that supports a meta-object model for application design and operating system interactions. The API includes an input component that receives data and/or instructions. The input component processes a meta-data model that interrelates data via a class hierarchy, wherein the class hierarchy includes relationship descriptions between class objects, attributes, rules, and/or behavioral descriptions. Another aspect includes a data management system that includes a component to receive an item having meta-data annotations. An analysis component determines at runtime a structure for the item via deployment of the meta-data annotations. The system can also include a framework component that defines meta-data class derivations, meta-data classes, meta-data integrity rules, and/or meta-data class behavior.
1. A system stored on computer readable media, comprising:
an input component that reads a meta-model to determine a structure of an item and stores the structure of the item to computer readable media,
the meta-model comprising at least one meta-relationship and at least one meta-class, the at least one meta-relationship describing one or more relationships between meta-classes, the at least one meta-class being a class encapsulating data employed to represent another class, and the at least one meta-class is identified via a globally unique identifier.
2. The system of claim 1 , the input component is associated with services that operate in conjunction with an operating system framework.
3. The system of claim 1 , the item is a document.
4. The system of claim 1 , the one meta-class is associated with a relational database.
5. The system of claim 1 , the at least one meta-class is identified via at least one of a name and a caption to facilitate application development.
6. The system of claim 1 , the at least one meta-relationship optionally including at least one meta-role.
7. A data management system stored on computer readable media, comprising:
a processing component that receives an item that comprises a meta-model, the meta-model comprising one or more meta-classes, the one or more meta-classes comprising classes encapsulating data employed to represent another class, the one or more meta-classes is identified via a globally unique identifier; and
an analysis component that determines at runtime a structure of the item by reading the meta-model and stores the structure of the item to computer readable media.
8. Computer executable instructions for performing a method to process meta-data, the computer executable instructions stored on computer readable media, the method comprising:
receiving at least one meta-model object, the meta-model object comprising at least one meta-relationship between two or more meta-model classes;
determining the structure of an item according to the meta-relationship between the two or more meta-model classes, the two or more meta-model classes are identified via a globally unique identifier; and
storing the structure of the item to computer readable media.
9. A computer implemented system stored on computer readable media, the system to facilitate determining the structure of an item, comprising:
means for modeling a meta-data object, the meta-data object comprising a meta-model, the meta-model comprising a meta-relationship between two or more classes, the two or more classes are identified via a globally unique identifier;
means for determining the structure of the item at least in part via the meta-relationship; and
means for storing the structure of the item to computer readable media.
