Datasets: activity-analysis-by-question Reference

Initialize dataset

Initialize an "activity-analysis-by-question" dataset via the SET reports/datasets endpoint.

To control which session data should be used for the Item bank analysis, choose from the following:

  • Specify file_count: 1 (or more) to upload an explicit list of sessions that should be considered for analysis. In this case, the endpoint returns URL(s) to which each input file must be uploaded before the data compilation job can commence. Read about the upload process for details.
  • Alternatively, specify file_count: 0 and provide any desired filter parameters. In this case, the data compilation job is queued immediately based on the given filters, and the endpoint response includes a corresponding job_reference for polling the job's progress.

Other parameters for the initialize request are described below:

Endpoint v1/reports/datasets
HTTP Method POST
Action Type set
dataset_type
string

Specifies the type of dataset to initialize. Must be activity-analysis-by-question.
file_count
int

Number of input data files to upload containing specific session IDs to be analyzed. The response object will contain this many file URLs. Specify 0 to skip this step and analyze all sessions, or to filter sessions using the filters object instead. Specify 1 to upload all the session IDs in one file. If your report is based on a large number of sessions, you may prefer to split your data into a number of smaller files.

N.B. You must either provide input files or specify session filters in the filters object below. But they are mutually exclusive, you cannot provide both.
filters
object

Specifies a set of filters for the report. The sessions matching your filter must all contain the same questions. Any sessions that contain different questions will be discarded before analysis. See the sessions-log output file for details on which sessions matched your filter, and which of those sessions were actually analyzed.
filters.activity_id
array

An array of string activity_id values. Up to 100 activity_id values may be provided.
filters.mintime
string

Optional filter to exclude sessions submitted before mintime. Values can be provided in either RFC3339 section 5.6 “yyyy-mm-ddThh:mm:ssZ+” or Unix timestamp format.
filters.maxtime
string

Optional filter to exclude sessions submitted after maxtime. Values can be provided in either RFC3339 section 5.6 “yyyy-mm-ddThh:mm:ssZ+” or Unix timestamp format.
options
object

Object containing report configuration parameters (see child attributes detailed below).
options.default_sort_field
string

String to determine the default sort field for data in the dataset. The datasets rows will be ordered using this field. The named field must be present in fields.
options.default_sort_order
string

String to determine sort order for rows. Valid values are:

  • desc: descending order.
  • asc: ascending order.

 

Default: desc
options.fields
array

Array of strings, specifying the fields to be calculated for all questions in the dataset. See the list of available fields.
options.summary_fields
array

Array of strings, specifying the summary fields to be calculated. These fields will appear in the dataset summary file. See the list of available fields.

If specifying an explicit list of sessions for the "activity-analysis-by-question" dataset, upload one or more JSON input files containing user_id and session_id properties. Responses for each user's set of session_id values will be combined together as if they were a single activity. The datasets implementation guide provides details on the upload process.

Endpoint v1/reports/datasets
HTTP Method POST
Action Type get
dataset_id
string

String identifier of the dataset to retrieve.
dataset_type
string

The type of dataset identified by dataset_id. Must be activity-analysis-by-question.
data[].type
string

String identifier of the type of output. Can be dataset or sessions-log.
data[].format
string

The file format of the output file. Can be json or csv.gz (compressed CSV).
