Abstract

A dynamically configurable list management system that supports list elements of multiple content types is presented. Each list element is associated with an element type via an element type identifier. The element type identifier uniquely identifies the element type to the list management system. Each property associated with each element type is included in the list. Each property is identified by a unique property identifier. When adding a list element of a new element type to an existing list that does not include any elements of the new element type, the list management system identifies every property associated with the new element type. For each property associated with the new element type, the list management system determines which properties are not already included in the list, and adds those properties that are not already including to the list.

Claims

1. A computer-implemented list management system for managing a list of a plurality of elements, the list comprising elements of a plurality of element types, each element having at least one property associated with a property name, a property type, and a value, wherein the list management system, upon receiving instructions to accept an element of a new element type not already included in the list of elements:

determines one or more properties of the new element type, each of the one or more properties of the new element type including a property name and a property type;

determines whether the one or more property names of the new element type are already included in the list;

for each of the one or more properties of the new element type having a property name not already included in the list, adds the property to the list, wherein when the property is added to the list, the property is also added as a new property for each of the plurality of elements of the list;

for each of the one or more properties of the new element type having a property name already included in a corresponding property of an existing element of the list, determines whether the property type for such property of the new element type matches the property type associated with the corresponding existing element of the list, and, if not, adds such property of the new element type to the list, including added such property as a new property for each of the plurality of elements of the list;

adds at least one property of existing elements of the list as a new property for the new element type; and

displays the list including at least some of the plurality of elements with at least some of the properties of the list available to each element in the list.

2. The list management system of claim 1, wherein each element in the list is associated with its element type by a element type identifier that uniquely identifies its element type.

3. The list management system of claim 2, wherein each property is associated with a unique property identifier.

4. The list management system of claim 3, wherein the list management system is configured to accept elements of the new element type prior to adding an element of the new element type to the list.

5. The list management system of claim 3, wherein the list management system is configured to accept elements of the new element type upon adding an element of the new element type to the list.

6. The system of claim 1, wherein property type comprises at least one of:

text string, numerical value, enumerated type, or floating point value.

7. A method, implemented on a computing device, for adding a new element type to an existing list of elements not of the new element type, the method comprising:

receiving an instruction to add the new element type to the existing list of elements, wherein each existing element of the list of elements has one or more properties associated with a property name, a property type, and a value;

determining one or more properties of the new element type, each of the one or more properties of the new element type including a property name and a property type;

determining whether the one or more property names of the new element type are already included in the list;

for each of the one or more properties of the new element type having a property name not already included in the list, adding that property of the new element type to the list and adding that property as a new property for each of the existing elements of the list;

for each of the one or more properties of the new element type having a property name already included in a corresponding property of one of the existing elements of the list, determining whether the property type for such property of the new element type matches the property type associated with the corresponding existing element of the list, and, if not, adding such property of the new element type to the list, including adding such property as a new property for each of the plurality of existing elements of the list;

adding one or more properties of the existing elements of the list as new properties of the new element type; and

displaying the existing list including the newly added element type and the newly added properties.

8. The method of claim 7, wherein each list element in the existing list is associated with an element type by an element type identifier that uniquely identifies its element type.

9. The method of claim 8, wherein each property is associated with a unique property identifier.

10. The method of claim 8, wherein the new element type is added to the existing list prior to accepting an element of the new element type to the existing list.

11. The method of claim 8, wherein the new element type is added to the existing list upon accepting an element of the new element type to the existing list.

12. A computer storage medium bearing computer-executable instructions which, when executed on a computing device, carry out a method for adding a list element of a new element type to an existing list comprising existing elements not of the new element type, each element in the existing list having at least one property associated with a value, the method comprising:

receiving an instruction to add the list element of the new element type to the list of existing elements, wherein each element of the list of existing elements has one or more properties associated with a property name, a property type, and a value;

determining properties of the new element type, each of the one or more properties of the new element type including a property name and a property type;

for each property of the new element type having a property name not already included in the list, adding the property to the list and adding the property as a new property for each of the existing elements of the list;

for each of the one or more properties of the new element type having a property name already included in a corresponding property of one of the existing elements of the list, determining whether the property type for such property of the new element type matches the property type associated with the corresponding existing element of the list, and, if not, adding such property of the new element type to the list, including adding such property as a new property for each of the plurality of existing elements of the list;

adding the list element of the new element type to the existing list and adding the properties of the existing elements of the list as new properties for the list element of the new element type; and

displaying the existing list including at least some of the elements of the list with at least some of the properties of the list available to each element in the list.

13. The method of claim 12, wherein each list element in the list is associated with an element type by an element type identifier that uniquely identifies the element type.

14. The method of claim 13, wherein each property is associated with a unique property identifier.

15. The method of claim 14, wherein the new element type is added to the existing list prior to accepting an element of the new element type to the list.

16. The method of claim 14, wherein the new element type is added to the existing list upon accepting an element of the new element type to the list.
