The P5 File format is the newest MRR file format and was implemented for production data submission in March 2025. It is a JSON file format with header (called Interrogation File) and detail (called Interrogation Field Data) sections. JSON is a standard data interchange format between systems and is human readable.  Refer to www.json.org for information about JSON (JavaScript Object Notation).  The most current schema is 2024-06. Refer to json-schema.org for information about schema used to validate JSON files.

 

P5 software can be used to create files of this type.

 

File Structure

The file contents are composed of header fields that describe and have metadata related to the data contained in the file and one or more MRR Event records.

 

 

Header Fields

The header fields provide a key to identify the contained set of records (File Name) and general information about the records contained within the file and under what PTAGIS MRR Project code they should be loaded.

 

Note: fields which are optional in the schema may be required when submitted to PTAGIS for data processing. See the table in the MRR > Data Specification page for more details about field definitions and requirements.

 

MRR Events

Each MRR event represents the record for one PIT-tagged fish. Field requirements are different for different data collection events. See the table in the MRR > Data Specification page for more details about field definitions and requirements.
