Abstract

Some of the embodiments herein provide a seamless cloud of storage. This storage may be content-addressable storage. An end application may or may not be exposed to the fact that content-addressable storage is used. Various embodiments herein provide event notification, which may allow applications or users to subscribe to particular events (such as storage of an X-ray by a particular entity). Some embodiments provide for a shared archive. A shared archive may provide homogeneous access to medical data, etc. that was previously stored into the CAS cloud by heterogeneous applications, varied data types, etc. Additionally, embodiments herein allow for the creation and distribution of virtual packages. For example, a user may create a virtual package for all images related to a patient so that she may have a virtual package of all of her medical data to present to a referring physician.

upon performance of the action associated with the event of the particular event type related to the one or more of the plurality of fixed medical data imaging files at the second content-addressable storage server, propagating an event notification through the content-addressable storage cloud; and

upon receipt of the event notification at the first content-addressable storage server, providing for notification to the first application of the event of the particular event type related to the one or more of the plurality of fixed medical data imaging files based upon the subscription of the first application to receive the plurality of event notifications related to the one or more of the plurality of fixed medical data imaging files.

2. The method of claim 1, wherein the method further comprises, upon performance of the action associated with the event of the particular event type, propagating data related to the action through the content-addressable storage cloud.

3. The method of claim 1, wherein the method further comprises, upon notification to the first application of the event of the particular event type, retrieving fixed medical image data related to the event notification at the first content-addressable storage server.

4. The method of claim 1, wherein providing for notification to the first application of the event of the particular event type comprises pushing a message related to the event of the particular event type to the first application.

5. The method of claim 1, wherein providing for notification to the first application of the event of the particular event type comprises the first application polling for the event of the particular event type.

6. The method of claim 1, wherein providing for notification to the first application of the event of the particular event type comprises the first application filtering arriving event notification for the event of the particular event type.

7. The method of claim 1, wherein propagating an event notification through the content-addressable storage cloud comprises broadcasting the event notification to one or more neighboring content-addressable storage servers.

8. The method of claim 1, wherein receiving the request for event notification of the particular event type of event comprises receiving a request for event notification of storage of medical image data.

9. The method of claim 1, wherein receiving the request for event notification of the particular event type of event comprises receiving a request for event notification of alteration of data related to a medical patient.

10. The method of claim 1, wherein receiving the request for event notification of the particular event type of event comprises receiving a request for event notification of deletion of medical image data.

11. A system for event notification in an interconnected content-addressable storage system, said system comprising:

a first content-addressable storage server comprising one or more computing devices configured to;

store a plurality of fixed medical data imaging files, each medical data imaging file associated with a globally unique identifier (GUID), wherein the GUID does not directly indicate a path or location of the GUID'"'"'s associated medical data imaging file;

receive a request from a second application distinct from a first application and distinct from the first content-addressable storage server, for subscription to a plurality of event notifications of a particular type of event associated with one or more of the plurality of fixed medical data imaging files; and

upon receipt of an event notification of the particular type of event, providing for notification to the first application of the event of the particular event type based upon the subscription to receive the plurality of event notifications of the particular type of event associated with the one or more of the plurality of fixed medical data imaging files,

wherein the event notification was received from a second content-addressable storage server, wherein the second content-addressable storage server;

received a request to perform an action associated with an event of the particular event type associated with the one or more of the plurality of fixed medical data imaging files;

performed the action associated with the event of the particular event type associated with the one or more of the fixed medical data imaging files; and

upon performance of the action associated with the event of the particular event type at the second content-addressable storage server, sent the event notification to the first content-addressable storage server.

12. The system of claim 11, wherein the first content-addressable storage server is further configured to, upon notification to the first application of the event of the particular event type, retrieve the one or more of the plurality of fixed medical data imaging files related to the event notification.

13. The system of claim 11, wherein providing for notification to the first application of the event of the particular event type comprises pushing a message related to the event of the particular event type to the first application.

14. The system of claim 11, wherein providing for notification to the first application of the event of the particular event type comprises the first application polling for the event of the particular event type.

15. The system of claim 11, wherein the event notification received at the first content-addressable storage server is received from the second content-addressable storage server through a content-addressable storage cloud that comprises the first and second content-addressable storage servers.
