Abstract

A data management method to host applications and manage storage, finding and retrieval of typed items with support for tagging, connections, and situated queries is provided.

Claims

1. A data management method for managing a plurality of objects, the method comprising:

providing, in a computing device data management system, one or more cells with each cell having an object container wherein each object container is capable of containing a plurality of types of items;

providing, in the computing device data management system, one or more connection elements within each cell such that each connection is between items in the same cell or items in different cells and each connection indicates an association between the items; and

providing, in the computing device data management system, tag elements within items that denote tags that are associated with each item wherein the tags indicate a context of the item so that the item is searchable based on the tag;

wherein each cell object container comprises one or more pieces of information linked with the cell object container wherein the one or more pieces of information are stored in a native XML format; and

wherein each piece of information in each cell object container is based on an abstract base type object having one or more general characteristics elements of an object including an ItemID element that specifies a unique item identifier and a KindID element that specifies a unique identifier that identifies a type of the content and one or more semantic property elements, and a plurality of base components, each base component being a child of the abstract base type object and inheriting the one or more general characteristics and one or more semantic properties, each base component being a container item kind that describes a type of object and encapsulates the particular type of object wherein each type of object associated with the system is represented by the abstract base type object and one of the base components.

2. The method of claim 1, wherein providing the one or more connection elements further comprises using a <

element within an <

ItemDetails>

child element of the abstract base type object to provide a connection between one or more items.

3. The method of claim 1, wherein providing the connection between items in the same cell further comprises providing a connection element containing information about a connection between a first object in one object container and a second object in same object container.

4. The method of claim 1, wherein providing the connection between items in different cells further comprises providing a connection element containing information about a connection between a first object in one object container and a second object in a different object container.

5. The method of claim 1 further comprising storing, in an embedded XML database, the one or more cells.

6. The method of claim 1 further comprising providing, in any cell, a situated query to retrieve data from the particular cell or from other cells.

7. The method of claim 6, wherein the situated query further comprises a type specification that specifies a type of item to return by the situated query.

8. The method of claim 6, wherein the situated query further comprises a scope where the scope describes a set of cells from which the situated query is to retrieve data.

9. The method of claim 8, wherein the scope further comprises one or more absolute references and one or more relative references combined with one or more operators.

10. The method of claim 9, wherein each of the one or more relative references are resolved relative to the context cell for the query.

11. The method of claim 8, wherein the situated query has a expression wherein the situated query with the expression returns all items in the cells identified by the scope which further match the expression.

12. The method of claim 6, wherein the situated query further comprises a page size that define a number of items to return at a time by the situated query.

13. The method of claim 6, wherein the situated query further comprises a maximum size that define a maximum number of items returned by the situated query.

14. The method of claim 11, wherein the expression of the situated query further comprises one of a kind element that defines a type of item which the situated query is supposed to return, a filter element that filters the items returned by the situated query, a connect element so that the situated query returns all items related to a defined item, a tag element so that the situated query returns all items that match the tag element with respect to the tags, an orderby element that orders the items returned by the situated query based on the values of a child element within each item, a groupby element that groups the items returned by the situated query based on the values of a child element within each item, a count element such that the situated query returns the count of items returned by the situated query in the event that the count element was not present and a condition element that limits the situated query based on the type of entities to be returned.

15. The method of claim 11, wherein the situated query further comprises a plurality of expressions combined together using a join operation wherein the situated query returns all items in the one or more cells identified by the scope that match one or more of the expressions.

16. The method of claim 1, wherein each base component has one or more semantic properties that are defined in the one or more semantic property elements and wherein the one or more semantic property elements further comprise a tag associated with an object.

17. The method of claim 16, wherein a tag further comprises a tag generated by a user or an automatically generated tag, wherein each automatically generated tag further comprises a tag type name, a role and a value of the role wherein the role is a reference to an element within the base component to which the tag is associated and wherein the tag type name further comprises a time tag type, a person tag type, a location tag type, a category tag type or a rating tag type.

18. The method of claim 1, wherein each base component has one or more semantic properties that are defined in the one or more semantic property elements and the one or more semantic property elements further comprise a note associated with an object.

19. The method of claim 1 further comprising creating a new base component for a new type of object, the new base component describing the new type of object and encapsulating the underlying content of the new type of object within a generic content element wherein the new type of object is represented by the new base component.

20. The method of claim 1, wherein the abstract base type object further comprises a views element, an actions element and a constraints element wherein the views element describes zero or more display types associated with the abstract base type object, the actions element describes zero or more actions associated with the abstract base type object and the constraints element describes zero or more constraints associated with the abstract base type object.
