Abstract

A system for transmitting data content and performing operations on the data content within a distributed system. Client machines within the system transmit to a server a request for a particular operation. The server constructs a response message, transmits it to the client, and also transmits it to other machines including a reference to the requested information.

Claims

1. An article of manufacture specifying a representation of an object stored in a computer-readable storage medium and capable of electronic transmission between machines in a distributed system, the article of manufacture comprising:

a data cell object to be transmitted in a network, the data cell object including a unique code identifying the object, a plurality of content flags identifying types of content within the object, a plurality of transmission flags specifying how to broadcast the content in the network, and a plurality of error flags specifying errors in the content;

wherein the plurality of content flags includes an indicator specifying whether the object contains content which has not yet been synchronized.

2. An article of manufacture specifying a representation of an object stored in a computer-readable storage medium and capable of electronic transmission between machines in a distributed system, the article of manufacture comprising:

a data cell object to be transmitted in a network, the data cell object including a unique code identifying the object, a plurality of content flags identifying types of content within the object, a plurality of transmission flags specifying how to broadcast the content in the network, and a plurality of error flags specifying errors in the content;

wherein the plurality of content flags includes an indicator specifying whether the object contains content which has been newly formed.

3. An article of manufacture specifying a representation of an object stored in a computer-readable storage medium and capable of electronic transmission between machines in a distributed system, the article of manufacture comprising:

a data cell object to be transmitted in a network, the data cell object including a unique code identifying the object, a plurality of content flags identifying types of content within the object, a plurality of transmission flags specifying how to broadcast the content in the network, and a plurality of error flags specifying errors in the content;

wherein the plurality of transmission flags includes an indicator specifying whether any changes to the content can be transmitted without transmitting the entire content.

4. An article of manufacture specifying a representation of an object stored in a computer-readable storage medium and capable of electronic transmission between machines in a distributed system, the article of manufacture comprising:

a data cell object to be transmitted in a network, the data cell object including a unique code identifying the object, a plurality of content flags identifying types of content within the object, a plurality of transmission flags specifying how to broadcast the content in the network, and a plurality of error flags specifying errors in the content;

wherein the plurality of transmission flags includes an indicator specifying whether any changes to the content should be transmitted with the content in its entirety.

5. An article of manufacture specifying a representation of an object stored in a computer-readable storage medium and capable of electronic transmission between machines in a distributed system, the article of manufacture comprising:

a data cell object to be transmitted in a network, the data cell object including a unique code identifying the object, a plurality of content flags identifying types of content within the object, a plurality of transmission flags specifying how to broadcast the content in the network, and a plurality of error flags specifying errors in the content;

wherein the plurality of transmission flags includes an indicator specifying whether one or more other objects which the data cell object references should also be transmitted when the data cell object is transmitted.

6. An article of manufacture specifying a representation of an object stored in a computer-readable storage medium and capable of electronic transmission between machines in a distributed system, the article of manufacture comprising:

a data cell object to be transmitted in a network, the data cell object including a unique code identifying the object, a plurality of content flags identifying types of content within the object, a plurality of transmission flags specifying how to broadcast the content in the network, and a plurality of error flags specifying errors in the content;

wherein the plurality of transmission flags includes an indicator specifying whether one or more other objects to which the data cell object has references should also be transmitted when the data cell object is transmitted.

7. An article of manufacture specifying a representation of an object stored in a computer-readable storage medium and capable of electronic transmission between machines in a distributed system, the article of manufacture comprising:

a data cell object to be transmitted in a network, the data cell object including a unique code identifying the object, a plurality of content flags identifying types of content within the object, a plurality of transmission flags specifying how to broadcast the content in the network, and a plurality of error flags specifying errors in the content;

an array containing a plurality of data elements; and

an array of flags, each flag corresponding to a data element, wherein each flag indicates whether the corresponding data element has changed.

8. An article of manufacture specifying a representation of an object stored in a computer-readable storage medium and capable of electronic transmission between machines in a distributed system, the article of manufacture comprising:

an enumeration data cell object to be transmitted in a network, the enumeration data cell object specifying one or more unique identifiers corresponding to one or more data cell objects;

an array of identifiers identifying said one or more data cell objects; and

an array of flags, each flag corresponding to a data cell object of said one or more data cell objects, wherein each flag indicates whether a content of the corresponding data cell object has been updated.

9. An article of manufacture specifying a representation of an object stored in a computer-readable storage medium and capable of electronic transmission between machines in a distributed system, the article of manufacture comprising:

an enumeration data cell object to be transmitted in a network, the enumeration data cell object specifying one or more unique identifiers corresponding to one or more data cell objects;

an array of identifiers identifying said one or more data cell objects; and

an array of flags, each flag corresponding to a data cell object of said one or more data cell objects, wherein each flag indicates whether a content of the corresponding data cell object has been added.

10. An article of manufacture specifying a representation of an object stored in a computer-readable storage medium and capable of electronic transmission between machines in a distributed system, the article of manufacture comprising:

an enumeration data cell object to be transmitted in a network, the enumeration data cell object specifying one or more unique identifiers corresponding to one or more data cell objects;

an array of identifiers identifying said one or more data cell objects; and

an array of flags, each flag corresponding to a data cell object of said one or more data cell objects, wherein each flag indicates whether a content of the corresponding data cell object has been deleted.

11. An article of manufacture specifying a representation of an object stored in a computer-readable storage medium and capable of electronic transmission between machines in a distributed system, the article of manufacture comprising:

an hierarchical data cell object to be transmitted in a network, the hierarchical data cell object specifying an indication of a plurality of data cell objects, the hierarchical data cell object further specifying a pointer identifying a parent data cell associated with the hierarchical data cell within a hierarchical structure of content;

wherein the plurality of data cell objects specified by the hierarchical data cell object contains data which is in a child relationship to the hierarchical data cell object.
