POMBA will include the functionality of validating processed data against Data Dictionary tool.
...
- Please get me the list of valid values for this attribute
- Here is a value, please tell me if it meets constraints of the attribute (length, type, regex, range, enum, etc.)
- Here is a subset of attributes in a larger reference table/object, please return full rows that match subset. Note, subset could be one attribute.
- Here is a fully qualified row in a reference table/object, please tell me if it's valid
Data Dictionary APIs
Specific APIs
POMBA will include interface to consume the following APIs:
...
| Code Block | ||||
|---|---|---|---|---|
| ||||
POST /commonModelElements/{commonModelElementId}/validateInstance
Operation: validateInstance
validates whether an instance conforms to a type (for example: a value conforms to the
constraints of an attribute type, or, one or more rows of values conforms to the constraints
of an instance table)
Inputs commonModelElementId: identifies the entity defining the constraints as
'entityType~entityName~entityVer'
Inputs (JSON body variables):
{ "instance": instanceSchema }
where instanceSchema is the instance to be validated
Outputs:
on success: status code 204
on failure: status code 400 with json array of error messages: [ errorMessage ]
other failure status codes may be returned if for instance the proxy
is down (503)
Note: a pointer to a file containing the validation errors will be returned;
if less than 1Meg of validation errors occur, they will also be returned
in the error message array
Headers:
x-authorization: Basic XXXXXXXXXXXXXXXX
Content-Type: application/json
Sample Request:
POST /commonModelElements/instance~nfValuesCatalog~1.0/validateInstance HTTP/1.1
{
“instance”: [
{
"LineofBusiness": "string",
"NFFunction": "string",
"NFNamingCode": "string",
"NFRole": "string",
"NFType": "string",
"NFCFunction": "string",
"NFCNamingCode": "string",
"OwningEntity": "string"
}
]
}
Sample Success Response:
HTTP/1.1 204 No Content
Sample Error Response:
HTTP/1.1 400
content-type: application/json
[
"error message 1"
] |
getInstanceTableRows
| Code Block | ||||
|---|---|---|---|---|
| ||||
POST /commonModelElements/{commonModelElementId}/getInstanceTableRowsWithMatchingColumns
Operation: getInstanceTableRows
returns an array of instance table rows containing the column values provided
as input
Inputs (pathstring variables):
commonModelElementId: identifies the instance table as 'instance~instName~version'
Inputs (JSON body variables):
{ "columnKey1": "columnValueToMatch1", "columnKey2": "columnValueToMatch2" }
where as many column keys as necessary must be supplied and the match is done
as an AND across all key values (i.e., all key values must match)
Outputs:
on success: status code 200 with [ instanceTableRows ]
on failure: status code 400 with json array of error messages: [ errorMessage ]
other failure status codes may be returned if for instance the proxy
is down (503)
Headers:
x-authorization: Basic XXXXXXXXXXXXXXXX
Content-Type: application/json
Sample Request:
POST /commonModelElements/instance~nfValuesCatalog~1.0/getInstanceTableRowsWithMatchingColumns
{
"NFRole": "NF-ROLE-A",
"NFType": "NF-TYPE-A",
}
Sample Success Response:
HTTP/1.1 200 OK
content-type: application/json
[
{
"LineofBusiness": "string",
"NFFunction": "string",
"NFNamingCode": "string",
"NFRole": "NF-ROLE-A",

"NFNamingCode": "string",
"NFRole": "NF-ROLE-A",
"NFType": "NF-TYPE -A",

}
]
Sample Error response:
HTTP/1.1 400
content-type: application/json
[
"error message 1",
"error message 2"
]

Validate Single Attribute
| Code Block | ||||
|---|---|---|---|---|
| ||||
POST /commonModelElements/{commonModelElementId}/validateInstance
Operation: validate attribute value
validates whether an instance conforms to a type for a single attribute
Inputs commonModelElementId: identifies the entity defining the constraints as
'attribute~attributeName~entityVer'
Inputs (JSON body variables):
{ "instance": instanceSchema }
where instanceSchema is the attribute value under a test
Outputs:
on success: status code 204
on failure: status code 400 with errorMessage
other failure status codes may be returned if for instance the proxy
is down (503)
Note: a pointer to a file containing the validation errors will be returned;
if less than 1Meg of validation errors occur, they will also be returned
in the error message array
Headers:
x-authorization: Basic XXXXXXXXXXXXXXXX
Content-Type: application/json
Sample Request:
POST /commonModelElements/attribute~nfRole~1.0/validateInstance HTTP/1.1
{
"instance": "someValue"
}
Sample Success Response:
HTTP/1.1 204 No Content
Sample Error Response:
HTTP/1.1 400
content-type: application/json
{
"error message 1"

Error Reporting
Confirm whether all of these are expected to be applicable to the data dictionary implementation
Code | Reason Phrase | Description |
200 | OK | The action has been performed successfully and the response includes the requested entity. Success response for GET requests |
201 | Created | The resource was successfully created |
202 | Accepted | The request has been accepted for processing, but the processing has not been completed. The request might or might not eventually be acted upon, as it might be disallowed when processing actually takes place. |
204 | No Content | The action has been performed successfully but the response does not contain an entity. |
304 | Not Modified | Returned by GET requests if the etag identified by the if-none-match request header matches the etag associated with the requested resource. |
400 | Bad Request | Many possible reasons not specified by the other codes (e.g., missing required parameters or incorrect format). |
401 | Unauthorized | Authentication failed or was not provided in the x-authorization header. |
403 | Forbidden | Authorization error: The client has insufficient permissions to access the resource |
404 | Not Found | The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent. |
405 | Method Not Allowed | A request was made of a resource using a request method not supported by that resource (e.g., using PUT on a REST resource that only supports POST). |
500 | Internal Server Error | The server encountered an internal error or timed out; please retry (general catch-all server-side error).HTTP 500 errors may be mapped to SVC1000 (no server resources). |
502 | Bad Gateway | The proxy was not able to get a valid response from the application server. |
503 | Service Unavailable | The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. |
504 | Gateway Timeout | The server, while acting as a gateway or proxy, did not receive a timely response from the upstream process. |
