Oms API GET Run Microdata aggregated - openmpp/openmpp.github.io GitHub Wiki

Read a "page" of aggregated microdata values from model run.

Result can include multiple aggregations of value attributes (float of integer type) and group by dimension attributes (enum-based or bool type). Aggregation(s) is a comma-separated list of Model Output Expressions of microdata value attributes. For example, two aggregations: OM_AVG(Income) , OM_MAX(Salary + Pension) and group by two dimension attributes: AgeGroup , Sex.

Page is part of output table values defined by zero-based "start" row number and row count. If row count <= 0 then all rows returned.

It is also possible to use parameter(s) in calculation, parameter must be a scalar of float or integer type. For example: OM_COUNT_IF(Income > param.High), where param.High is a value of scalar parameter High in that model run.

Enum-based microdata attributes returned as enum codes.

Following aggregation functions avaliable:

OM_AVG mean of accumulators sub-values
OM_SUM sum of accumulators sub-values
OM_COUNT count of accumulators sub-values (excluding NULL's)
OM_COUNT_IF count values matching condition
OM_MAX maximum of accumulators sub-values
OM_MIN minimum of accumulators sub-values
OM_VAR variance of accumulators sub-values
OM_SD standard deviation of accumulators sub-values
OM_SE standard error of accumulators sub-values
OM_CV coefficient of variation of accumulators sub-values

Methods:

GET /api/model/:model/run/:run/microdata/:name/group-by/:group-by/calc/:calc
GET /api/model/:model/run/:run/microdata/:name/group-by/:group-by/calc/:calc/start/:start
GET /api/model/:model/run/:run/microdata/:name/group-by/:group-by/calc/:calc/start/:start/count/:count

Arguments:

:model - (required) model digest or model name

Model can be identified by digest or by model name. It is recommended to use digest because it is uniquely identifies model. It is possible to use model name, which is more human readable than digest, but if there are multiple models with same name in database than result is undefined.

:run - (required) model run digest, run stamp or run name

Model run can be identified by run digest, run stamp or run name. It is recommended to use digest because it is uniquely identifies model run. Run stamp, if not explicitly specified as model run option, automatically generated as timestamp string, ex.: 2016_08_17_21_07_55_123. It is also possible to use name, which is more human readable than digest, but if there are multiple runs with same name in database than result is undefined.

:name - (required) microdata entity name

:group-by - (required) comma-separated list of dimension attribute(s) to group by aggreagated values, dimension attribute must be enum-based or boolean type.

:calc - (required) comma-separated list of aggregation of microdata value attribute(s), value attribute must be float of integer type.

:start - (optional) start "page" row number, zero-based.
:count - (optional) "page" size, number of rows to select, if count <= 0 then all rows selected.
