Abstract

Examples are generally directed towards managing query responses. A server receives an unspecified property request associated with a resource. The request identifies a resource and omits a property field parameter. A set of instances associated with the resource is identified. An identifier for each instance in the set of instances is identified to form a set of identifiers. The server returns only the set of identifiers to the client as a response to the unspecified property request. On determining the server has received a types-feed request from the client, the server identifies all possible property types for the resource to form a list of all property types. The server returns the list of all property types to the client as a response to the types-feed request.

Claims

1. A server, comprising:

at least one processor; and

a memory storage device, the memory storage device comprising a memory area storing an unspecified property component,

wherein the unspecified property component is configured to return only an identifier of each instance associated with a resource identified in an unspecified property request,

wherein the at least one processor executes the unspecified property component to;

receive the unspecified property request for data associated with the identified resource from a client;

determine that the unspecified property request does not include a property field; and

having determined that the unspecified property request does not include the property field;

identify a set of instances associated with the resource;

obtain the identifier of each instance in the set of instances to form a set of identifiers;

generate a default response to the unspecified property request in accordance with a representational state (REST) application programming interface (API), the default response comprising the set of identifiers and excluding all properties associated with the resource except the identifier of each instance in the set of instances; and

return the default response to the client,

wherein the memory area further stores a types-feed component, and

wherein the at least one processor executes the types-feed component to receive a types-feed request for the resource, the types-feed request comprising a request for all available property types associated with the resource.

2. The server of claim 1, wherein the default response is a first response and wherein the at least one processor further executes the types-feed component to:

generate a second response,

wherein the second response comprises a list of all property types associated with the resource; and

return the second response to the client.

3. The server of claim 1, wherein the unspecified property request is a first request, and further comprising:

a system management component,

wherein the at least one processor further executes the system management component to;

receive a second request for data associated with the resource from a client;

determine that the second request includes the property field comprising a first property of the resource and a second property of the resource, the property field within the second request expanding an amount of data returned to the client; and

return a second response to the client, the second response comprising a first value associated with the first property for each instance in the set of instances, a second value associated with the second property for each instance in the set of instances, and the set of identifiers for the set of instances.

4. The server of claim 3, wherein the at least one process further executes the computer executable code to:

return an error to the client indicating a requested property is unavailable on determining the second property for a given instance in the set of instances is unavailable.

5. The server of claim 3, wherein object dependencies are explicitly documented within source code.

6. The server of claim 1, wherein the unspecified property request is a GET request.

7. The server of claim 1, wherein the unspecified property request is a POST request, the default response to the POST request including the data associated with the identified resource.

18. The server of claim 1, wherein the at least one processor further executes the unspecified property component, having determined that the unspecified property request does not include the property field, to generate the default response, the default response including (i) an entry count indicating a total number of instances in the set of instances, and (ii) a list of the instances in the set of instances, the list having a number of entries equal to the total number of instances, each of the entries in the list including the identifier of a respective instance in the set of instances.

19. The server of claim 2, wherein the at least one processor further executes the types-feed component to generate the second response, the second response including the list of all property types associated with the resource, the list having a number of entries equal to a total number of the property types, each of the entries in the list including at least a name of a respective property, a type of the respective property, and a description of the respective property.

20. The server of claim 3, wherein the at least one processor further executes the system management component to generate the second response, the second response including (i) an entry count indicating a total number of instances in the set of instances, and (ii) a list of the instances in the set of instances, the list having a number of entries equal to the total number of instances, each of the entries in the list including (i) the identifier of a respective instance in the set of instances, (ii) the first value associated with the first property of the respective instance in the set of instances, and (iii) the second value associated with the second property of the respective instance in the set of instances.

8. A computer-implemented method for managing query responses by a computing device, comprising:

processing a first request for data associated with a resource by at least one processing device associated with a server;

determining, by an unspecified property component, that the first request does not include a property field; and

having determined that the first request does not include the property field;

obtaining, by the unspecified property component, an identifier of each instance in a set of instances of the resource to form a set of identifiers; and

generating a default response to the first request by the server, the default response comprising the set of identifiers and excluding all properties associated with the resource except the identifier of each instance in the set of instances;

receiving a second request comprising a types-feed parameter, the types-feed parameter comprising an identification of the resource;

generating a second response, by a types-feed component, the second response comprising a list of all available property types associated with the resource; and

returning the second response to the client.

9. The computer-implemented method of claim 8, wherein the first request is received from a client and further comprising:

returning the default response to the client via an application programming interface of a server.

10. The computer-implemented method of claim 9, wherein the application programming interface is a representational state transfer (REST) application programming interface.

11. The computer-implemented method of claim 8, further comprising:

receiving a third request for data associated with the resource from a client;

determining that the third request includes the property field comprising a first property of the resource and a second property of the resource, the property field within the third request expanding an amount of data returned to the client; and

returning a second response to the client, the second response comprising a first value associated with the first property for each instance in the set of instances, a second value associated with the second property for each instance in the set of instances, and a third value associated with the identifier of each instance in the set of instances.

12. The computer-implemented method of claim 11, further comprising:

receiving the first request from a client by a representational state transfer (REST) application programming interface (API) of a server.

13. The computer-implemented method of claim 11, further comprising:

upon determining that the second property for a given instance in the set of instances is unavailable, returning an error to the client indicating a requested property is unavailable.

14. The computer-implemented method of claim 8, wherein object dependencies are explicitly documented within source code.

15. One or more computer storage devices embodying computer executable components, said components comprising a systems management component that, when executed, cause at least one processor to:

receive a GET request for data associated with a resource from a client via a representational state (REST) application programming interface (API), the GET request comprising an identification of the resource;

determine that the GET request does not include a property field specifying a property associated with the resource; and

having determined that the GET request does not include the property field;

identify a set of instances associated with the resource;

obtain an identifier of each instance in the set of instances to form a set of identifiers; and

generate a default response to the client via the REST API, the default response comprising the set of identifiers and excluding all properties associated with the resource except the set of identifiers;

process a types-feed request received from a client, the types-feed request comprising the identification of the resource;

identify a set of properties associated with the resource;
