MyCogMobile requirements (DRAFT)

This document describes the requirements for the MyCogMobile (MCM) study. This study is expected to launch in mid-July.

Requirements:

1. MCM is iOS only

2. ETL/parquet/scoring not required

3.  …

Schema implementation description from Northwestern:

MyCogMobile task result data is expected to validate against the shared schema.

MyCogMobile does not include a “self referencing” schema, but should be validated using the mechanism outlined at https://sagebionetworks.jira.com/wiki/spaces/BD/pages/2883715106/Self-Referencing+Data#Support-for-self-referencing-data . ie,

The approach that Northwestern took:

create a MyCogMobileSubTaskStep which conforms to RSDSubtaskStep and could represent a “submeasure” such as the MyCogMobile specific Memory For Sequences.  That enabled us to include entries in our MyCogMobile step description JSON which delegated to other step description JSON files like this:

    {
      "identifier": "MyCogMobileMFS",
      "type": "subTaskStep"
    },

When the measure encounters something like this, then it essentially loads the MyCogMobileMFS measure. However, at the end of MyCogMobile all of the data across the “submeasures” is aggregated into a single MyCogMobileTaskResult which will validate against the shared schema.
