Abstract

Data sets of various types may be accessible through a host according to a protocol, such as a RESTful HTTP interface. Various domains may involve domain-specific processes to be executed as pre-triggers or post-triggers of various protocol requests (e.g., an HTTP GET request specifying a Read operation on an access-restricted data set may involve an authorization operations set that verifies the access privileges of the requester.) A host of the data set may be configured to receive a resource script expressing the operations set in a script language, to store the resource script, and to associated it with at least one data set and at least one verb of the protocol. Upon later receiving a protocol request specifying the verb and the resource, the host may then execute the resource script (as a pre-trigger and/or as a post-trigger) in accordance with the business logic of the domain.

Claims

1. A method of executing an operations set on a data set accessible through a host according to a protocol, comprising:

expressing the operations set as a resource script in a script language, and

configuring the host to execute the resource script upon executing a protocol request specifying the verb on the data set.

2. The method of claim 1, the configuring comprising at least one of:

configuring the host to execute the resource script before executing a verb of the protocol on the data set, and

configuring the host to execute the resource script after executing a verb of the protocol on the data set.

3. The method of claim 1:

the data set comprising a resource represented in a domain, and

the operations set specifying a domain-specific operation on the data set within the domain.

4. The method of claim 1, the data set comprising at least one resource represented in a deployable computing environment hosted by the host.

5. The method of claim 1:

the protocol comprising HTTP;

the verbs of the protocol comprising HTTP POST, HTTP GET, HTTP PUT, and HTTP DELETE; and

the host comprising an HTTP endpoint.

6. The method of claim 1, the script language comprising a declarative script language.

7. The method of claim 1:

the script language comprising;

at least one data set instruction corresponding to at least one verb of the protocol, and

at least one flow control instruction configured to alter an execution flow of the resource script; and

the resource script comprising at least one data set operation and at least one flow control operation.

8. The method of claim 1, the resource script comprising at least one operation specifying at least one data binding with at least one aspect of the protocol request.

9. The method of claim 1:

the resource script generating a result, and

the method comprising;

receiving the result included in a protocol response returned by the host in response to the protocol request.

10. A method of executing a resource script on a data set accessible according to a protocol, comprising:

upon receiving the resource script;

storing the resource script, and

associating the resource script with a verb of the protocol and the data set; and

upon receiving a protocol request specifying the verb, executing the resource script on the data set.

11. The method of claim 10, the executing comprising at least one of:

executing the resource script before executing the verb of the protocol on the data set, and

executing the resource script after executing the verb of the protocol on the data set.

12. The method of claim 10:

the resource script comprising a predicate condition of the verb, and

the executing comprising;

executing the resource script before executing the protocol request, and

conditioning executing the protocol request on a fulfilling of the predicate condition of the resource script.

13. The method of claim 10:

the data set comprising a resource represented in a domain, and

the operations set specifying a domain-specific operation on the data set within the domain.

14. The method of claim 10, the data set comprising at least one resource represented in a deployable computing environment.

15. The method of claim 14:

the storing comprising;

storing the resource script in the deployable computing environment; and

the associating comprising;

associating the resource script with the data set in the deployable computing environment.

16. The method of claim 10:

the protocol comprising HTTP;

the verbs of the protocol comprising HTTP POST, HTTP GET, HTTP PUT, and HTTP DELETE; and

the host comprising an HTTP endpoint.

17. The method of claim 10, the receiving comprising:

inspecting the resource script for at least one of;

a script language error, and

a resource script vulnerability; and

upon validating the resource script;

storing the resource script, and

associating the resource script with the verb of the protocol and the data set.

18. The method of claim 10:

the resource script comprising at least one operation specifying at least one data binding with at least one aspect of the protocol request; and

executing the resource script comprising;

data binding the at least one operation with the at least one aspect of the protocol request.

19. The method of claim 10:

the resource script generating a result, and

the method comprising;

returning the result of the resource script with a protocol response generated in response to the protocol request.

20. A method of executing an operations set specifying a domain-specific operation on a data set comprising a resource represented in a domain in a deployable computing environment hosted by a host and accessible according to a protocol, comprising:

expressing the operations set as a declarative resource script in a script language comprising;

at least one data set instruction corresponding to at least one verb of the protocol, and

at least one flow control instruction configured to alter an execution flow of the resource script,

the resource script comprising at least one data set operation and at least one flow control operation; and

configuring the host to at least one of;

execute the resource script before executing a verb of the protocol on the data set, and

execute the resource script after executing a verb of the protocol on the data set; and

receiving a result generated by the resource script and included in a protocol response returned by the host in response to the protocol request.
