Abstract

A resource may be identified according to multiple Uniform Resource Locators (“URL”) according to systems and methods for encapsulating an alternative URL inside a primary “carrier” URL to form a compound URL or “smart link” and for processing smart links thereby formed. A preferred URL may be encapsulated into a smart link for use by client devices that support handling of the preferred URL, while other client devices may use a default or fallback URL that is also encapsulated into the smart link. The alternative URL is indicated by a pre-determined key included in the primary carrier URL.

Claims

1. A computer-implemented method for accessing a compound Uniform Resource Locater (“

URL”

), the method comprising;

obtaining, by a client device, an indication to access a particular resource identified by the compound URL, the compound URL identifying said particular resource according to at least a primary scheme-name, a hierarchical portion, and a key/value portion, said key/value portion including at least one key/value pair;

parsing said key/value portion, by said client device, to determine whether said at least one key/value pair includes an alternative-URL key/value pair identified according to a predetermined alternative-URL key; and

when said at least one name/value pair is determined to include said alternative-URL key/value pair;

extracting a value string from said alternative-URL key/value pair, said value string encapsulating an alternative-URL payload representing at least an alternate scheme-name;

determining whether an alternative-application for accessing resources according to said alternate scheme-name is installed on the computer; and

when said alternative-application is installed on the computer, invoking said alternate application to access said particular resource.

2. The method of claim 1, further comprising, prior to parsing said key/value portion, determining that no primary-application for accessing resources according to said primary scheme-name is installed on the computer, and wherein parsing said key/value portion is performed in response to said determining that no such primary-application is installed on the computer.

3. The method of claim 1, further comprising, when said alternative-application is not installed on the computer:

determining that a primary-application for handling said primary scheme-name is installed on the computer; and

invoking said primary-application to access said particular resource.

4. The method of claim 3, wherein invoking said primary-application to access said particular resource comprises passing the compound URL to said primary-application.

5. The method of claim 3, wherein said primary scheme-name is an http scheme-name, and wherein said primary-application comprises a general-purpose web-browsing application standardly installed on said client device.

6. The method of claim 1, wherein said alternate scheme-name is a non-http scheme-name, and wherein said alternate application comprises a special-purpose application optionally installed on said client device.

7. The method of claim 1, further comprising, when said at least one name/value pair is determined to include said alternative-URL key/value pair, determining an alternate URL identifying said particular resource according to at least said alternate scheme-name and an alternate hierarchical portion.

8. The method of claim 7, wherein determining said alternate URL comprises decoding said alternative-URL payload to obtain said alternate URL.

9. The method of claim 1, wherein obtaining said indication to access a particular resource identified by the compound URL comprises optically scanning a machine-scannable code encoded with the compound URL.

10. A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, perform the method of claim 1.

11. A computing apparatus comprising a processor and a storage medium storing instructions that, when executed by the processor, perform the method of claim 1.

12. A computer-implemented method for encoding an alternative Uniform Resource Locater (“

URL”

) into a compound URL, the method comprising;

obtaining, by the computer, a first URL identifying a particular resource that is accessible via a first application on a first plurality of client devices and a second application on a second plurality of client devices, said first URL comprising a first scheme-name, which refers to a first identifier-scheme that can be handled by said first application, but that cannot be handled by said second application, a first hierarchical portion, and a first key/value portion including zero or more key-value pairs;

obtaining, by the computer, a second URL identifying said particular resource, said second URL comprising a second scheme-name referring to a second identifier-scheme that can be handled by said second application, but that cannot be handled by said first application;

generating, by the computer, an alternative-URL payload string that can be validly represented within said first URL according to said first identifier-scheme and that encapsulates information sufficient to indicate said second URL;

obtaining, by the computer, a predetermined alternative-URL key recognized by URL-handling routines on said second plurality of client devices as indicating the presence of an alternative URL;

generating, by the computer, an alternative-URL key/value pair comprising said predetermined alternative-URL key and said alternative-URL payload string;

inserting, by the computer, said alternative-URL key/value pair into said first key/value portion to form an alternative-URL-encoded compound URL; and

storing said alternative-URL-encoded compound URL in a memory associated with the computer.

13. The method of claim 12, further comprising providing, by the computer, said alternative-URL-encoded compound URL for transmission to said first and said second pluralities of client devices, such that said particular resource can be accessed on any given client device by a selected one of said first application and said second application.

14. The method of claim 13, wherein providing said alternative-URL-encoded compound URL comprises:

encoding said alternative-URL-encoded compound URL into an optically machine-scannable code; and

providing said optically machine-scannable code for transmission to said first and said second pluralities of client devices.

15. The method of claim 12, wherein generating said alternative-URL payload string comprises encoding, by the computer, said second URL into an encoded second URL that can be validly represented within said first URL according to said first identifier-scheme.

16. The method of claim 15, wherein encoding said second URL into said encoded second URL comprises:

determining, by the computer, a set of reserved characters that are disallowed according to said first identifier-scheme; and

encoding, by the computer, said second URL into said encoded second URL such that any members of said set of reserved characters that appear in said second URL are represented in said encoded second URL by an equivalent data octet.

17. The method of claim 12, wherein said first URL and said second URL are identical except for said first scheme-name and said second scheme-name.

18. The method of claim 17, wherein generating said alternative-URL payload string comprises copying said second scheme-name into said alternative-URL payload string.

19. A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, perform the method of claim 12.

20. A computing apparatus comprising a processor and a storage medium storing instructions that, when executed by the processor, perform the method of claim 12.
