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 system for managing a plurality of objects, the system comprising:

a computing device that has at least one processing unit that executes a data management system;

at least one storage unit that is coupled to the computing device;

the at least one storage unit comprises one or more cells, each cell having an object container wherein each object container is capable of containing a plurality of types of items, one or more connection elements within each cell such that each connection is one of between items in the same cell and items in different cells and each connection indicates an association between the items, a tag element within items of each cell 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 and the object container contains one or more pieces of information linked with the 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 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 system of claim 1, wherein each of the one or more connection elements has a <

RelatedItem>

element within an <

ItemDetails>

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

3. The system of claim 1, wherein the one or more cells are stored, in an embedded XML database.

4. The apparatus of claim 1, wherein each cell has a situated query to retrieve data from the particular cell or from other cells.

5. The system of claim 4, wherein the situated query is a type specification that specifies a type of item to return by the situated query.

6. The system of claim 4, wherein the situated query has a scope and the scope describes a set of cells from which the situated query is to retrieve data.

7. The system of claim 6, wherein the scope has one or more absolute references and one or more a relative references combined with one or more operators.

8. The system of claim 7, wherein each of the one or more relative references are resolved relative to the context cell for the query.

9. The system of claim 4, 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.

10. The system of claim 4, wherein the situated query has a page size that define a number of items to return at a time by the situated query.

12. The system of claim 4, wherein the situated query has a maximum size that define a maximum number of items returned by the situated query.

13. The system of claim 9, wherein the expression of the situated query has 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.

14. The system of claim 4, wherein the situated query has 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.

15. The system 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.

16. The system of claim 15, wherein the tag associated with the object 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.

17. The system 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.

18. The system 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.
