# POST Model Arrayset Data¶

GET /models/(mid)/arraysets/(aid)/data

Retrieve data stored in arrayset darray attributes. The caller may request data stored using any combination of arrays, attributes, and hyperslices.

Parameters: Request Headers: mid (string) – Unique model identifier. aid (string) – Arrayset artifact id. Content-Type – application/json hyperchunks (string) – The request must contain a parameter hyperchunks that specifies the arrays, attributes, and hyperslices to be returned, in Hyperchunks format. byteorder (string) – The request may optionally contain a parameter byteorder that specifies that the response should be binary data with the given endianness. The byteorder parameter must be either “little” or “big”. Note that the byteorder parameter can only be used if every attribute in every hyperchunk is of numeric type. If the byteorder parameter is used, the request must accept application/octet-stream as the result content-type, and the response data will contain contiguous raw data bytes in the given byteorder, in the same order as the requested hyperchunks / hyperslices. For multi-dimension arrays, hyperslice array elements will be in “C” order (the last coordinate varies the fastest). If the byteorder parameter isn’t specified, the response data will be a JSON-encoded array with length equal to the total number of hyperslices. Each element in this top level array will be an array containing the data for the corresponding hyperslice, in the same order as the requested hyperchunks / hyperslices. For multi-dimension arrays, data for the corresponding hyperslice will be nested further, in “C” order (the last Content-Type – application/json

The following request will return all of the data for array 0, attribute 1 from an arrayset artifact with id “foo”:
