1. Info: Software source code *SHOULD* link to a continuous integration service that builds the software and runs the software's tests (This is missing in the metadata)
2. Info: An interface type *SHOULD* be expressed: Software source code should define one or more target products that are the resulting software applications offering specific interfaces (This is missing in the metadata)
3. Info: Reference publications *SHOULD* be expressed, if any (This is missing in the metadata)
4. Info: The funder *SHOULD* be acknowledged (This is missing in the metadata)
