Copying field data

When collecting data from the field, you'll want to grab the qbank assessment data as well as any student uploaded files.

MongoDB

For a gstudio / MongoDB installation, just do a mongodump and you'll have all the qbank data! Depending on your configuration, it will most likely be stored in the following databases

• assessment
• assessment_authoring
• hierarchy
• id
• logging
• relationship
• repository
• resource

Specific collections

In the field, student-responses is only saved in certain database collections -- the remainder is data used to serve the assessments, and does not change in the field. Student-related data is in:

• assessment/AssessmentSection
• assessment/AssessmentTaken
• logging/Log
• logging/LogEntry
• repository/Asset
• repository/Repository

Also, any files uploaded as part of an assessment are put into the webapps/CLIx/studentResponseFiles directory (see below for more details).

Make sure that all of the above data is saved by the field service provides and transported back to the central data store, for analytics and research purposes.

NOTE If you expect that teachers in the field will be authoring new content, then you MUST save / export the entire MongoDB datastore (not just the student-specific collections listed above), so that you capture the new questions and assessments.

Filesystem storage

For an unplatform installation, the JSON data files will be located in the webapps/ directory under the qbank installation (the path can be found by visiting https://localhost:8080/datastore_path). You'll want to copy the entire webapps/CLIx/ directory (will include the student-uploaded files).

On Windows, there is also a script provided in unplatform, called DataExtractionScript.bat. Just run that script and copy the resulting zip file.

Student-uploaded files

In either of the two above situations (gstudio or unplatform), you still need to copy the student-uploaded files, which are not stored in GridFS, but instead are stored on the filesystem. These files will be located in the webapps/ directory under the qbank installation (the full path can be found by visiting https://localhost:8080/datastore_path). You'll want to copy the entire webapps/CLIx/studentResponseFiles/ directory.
