Describe Primary data origin

[kyyberi]

It is data genesis!

Which problem is this feature request solving?

• Where and from whom data came from.
• Currently ODPS does not offers any attributes or mechanism to define it.
• Expands the checksums etc

Describe the solution you'd like

1. A way to surely identify define the source, provide the mechanism to describe it
2. What kind of steps in between. From where it started and what was the path. Verify the stakeholders?
3. What kind of entities: machine, human, or something else is related
4. Where and by what exactly the data was created, prove it. Authenticity
5. This is something similar to observability, but this is about describing the context among other things from the actual sources behind the value chain (backward)

Any known practical use cases to apply?

Yes we do. It will provide business value. This is coming from practitioners. Details not revealed yet to protect frontrunner business

Implemented first version of this in the DataOps component. The origin attempts to describe the sources of data

dataOps:
  data:
    schemaLocationURL: http://http://192.168.10.1/schemas/2016/petshopML-2.3/schema/petstore.xsd
    origin:
      - source: human # sensor, human, analytics
        sourceId: 
        type: raw # raw, cleansed
        description: 
        checksum: # ?
      - source: sensor # sensor, human, analytics
        sourceId: 
        type: cleansed # raw, cleansed
        description: 
        checksum: # ?

Can we somehow add here "as code" part as well? A method to verify the source system and authenticity of the data directly?

Something similar to what is in data quality

dataQuality:
  - dimension: accuracy
    objective: 98
    unit: percentage
    monitoring:
      type: SodaCL 
      spec:
        - require_unique(member_id) 
        - require_range(age_band, 18, 100)
