Abstract

Systems and methods for sharing document annotations. A document is displayed on a graphical user interface and first annotation information for the document is created by a first user, the annotation information including first annotations and positioning information for positioning a first overlay window relative to the document. The first overlay window with the first annotations is displayed over the document wherein the document is visible through the first overlay window. The annotation information is sharable with other users, whereby a different user is able to display the overlay with annotations made by the first user over the document on a different system, and the annotations do not modify the underlying document.

Claims

1. A database system, comprising:

a processing system; and

a memory device coupled to the processing system, the memory device having instructions stored thereon that, in response to execution by the processing system, cause the processing system to perform operations comprising;

storing, by the processing system of the database system, a plurality of subscriptions, each of the subscriptions associated with a different subscriber of a plurality of subscribers, each subscriber associated with a permission level of a plurality of permission levels;

receiving first information uploaded from a first remote user system over a network, wherein the first information comprises annotation information including annotations and positioning information;

determining whether to grant one of the subscribers access to the annotations; and

in response to determining to grant the one of the subscribers access to the annotations, downloading second information that is different than the received first information to a second remote user system that is different than the first remote user system.

2. The database system of claim 1, wherein the operations further comprise:

determining a pixel count associated with the second remote user system;

determining a product of the pixel count and a quotient of a pixel count of an overlay window of the annotation information and a pixel count associated with the first remote user system; and

generating the second information responsive to determining the product.

3. The database system of claim 1, wherein the operations further comprise:

in response to determining to grant the one of the subscribers access to the annotations, determining whether a value corresponding to the one of the subscribers is equal to a predetermined value;

downloading third information to the second remote user system in response to determining that the value corresponding to the one of the subscribers is not equal to the predetermined value.

4. The database system of claim 1, wherein the operations further comprise scaling, by the database system, the annotation information to generate the second information, wherein the generated second information includes annotation information that is different than the annotation information of the first information.

5. The database system of claim 1, wherein the operations further comprise:

generating, by the database system, an overlay window to be displayed over a portion of a document associated with the annotation information, the overlay window including the annotations and in accordance with the positioning information; and

generating the second information based on the overlay window.

6. The database system of claim 1, wherein the operations further comprise:

receiving a request from the second remote user system to incorporate the first information into a document retained by the database system; and

updating, by the database system, a record of the database system that corresponds to the document responsive to receiving the request.

7. The database system of claim 1, wherein the positioning information includes a first value corresponding to at least one of a size or resolution of a document that corresponds to the annotation information.

8. The database system of claim 7, wherein the positioning information includes a second value corresponding to a document zoom.

9. The database system of claim 8, wherein the positioning information includes a third value corresponding to a document position.

10. The database system of claim 9, wherein the operations further comprise scaling, by the database system, at least a portion of the first information using the first value, the second value, and the third value.

11. The database system of claim 10, wherein the operations further comprise determining a pixel count corresponding to the second remote user system, wherein the scaling by the database system is responsive to determining the pixel count corresponding to the second remote user system.

12. A method, comprising:

storing, by a processing system of a database system, a plurality of subscriptions, each of the subscriptions associated with a different subscriber of a plurality of subscribers, each subscriber associated with a permission level of a plurality of permission levels;

receiving at the database system first information uploaded from a first remote user system that is coupled to the database system over a network, wherein the first information comprises annotation information including annotations and positioning information;

determining whether to grant one of the subscribers access to the annotations; and

in response to determining to grant the one of the subscribers access to the annotations, downloading second information that is different than the received first information to a second remote user system that is different than the first remote user system.

13. The method of claim 12, further comprising:

determining a pixel count associated with the second remote user system;

determining a product of the pixel count and a quotient of a pixel count of an overlay window of the annotation information and a pixel count associated with the first remote user system; and

generating the second information responsive to determining the product.

14. The method of claim 12, further comprising:

in response to determining to grant the one of the subscribers access to the annotations, determining whether a value corresponding to the one of the subscribers is equal to a predetermined value;

downloading third information to the second remote user system in response to determining that the value corresponding to the one of the subscribers is not equal to the predetermined value.

15. The method of claim 12, further comprising scaling, by the database system, the annotation information to generate the second information, wherein the generated second information includes annotation information that is different than the annotation information of the first information.

16. The method of claim 12, further comprising:

generating, by the database system, an overlay window to be displayed over a portion of a document associated with the annotation information, the overlay window including the annotations and in accordance with the positioning information; and

generating the second information based on the overlay window.

17. The method of claim 12, further comprising:

receiving a request from the second remote user system to incorporate the first information into a document retained by the database system; and

updating, by the database system, a record of the database system that corresponds to the document responsive to receiving the request.

18. The method of claim 12, wherein the positioning information includes a first value corresponding to at least one of a size or resolution of a document that corresponds to the annotation information.

19. The method of claim 18, further comprising:

determining a pixel count corresponding to the second remote user system; and

scaling, by the database system, at least a portion of the first information using the first value, a second value included in the positioning information and corresponding to a document zoom, and a third value included in the positioning information and corresponding to a document position, wherein the scaling is responsive to determining the pixel count corresponding to the second remote user system.

20. The method of claim 14, wherein the third information includes a document that is associated with the annotations.
