PiM

Main business logic will be declared in standard Schematron and XSLT. how to say: it’s out there in the open, declarative language

Step 1: Validation

Step 2: PREMIS to PiM

Step 3: PiM to PREMIS

Part 4: Any File to PREMIS

Step 5: NON PROFIT!

Development Issues

• things that BP allows but don’t convert cleanly will either be a warning or brought before the PREMIS community.
• pathological cases (like above) will be codified as test fixtures to establish a determinate behavior.
• GAP analysis & error handling
  • any conversion input must be valid (by some validation method)
    • if input is invalid a 400 class response is produced with information about why it is a bad request.
  • any conversion output must be valid (by some validation method)
    • if conversion output is invalid but input is valid then 500 class server error is produced and details saved for developers. this case is what we hope to minimize.
