Populated ScanCode wrapper to include copyright and author information.
Currently using FOSSology copyright and author database tables to insert these information.
FOSSology Scheduler is calling ScanCode for copyright and author along with licenses.

Asked how to copyright agent is generating hash for copyright and author tables?
- Hash is md5(content).
What is clearing table in copyright agent database here ?
- This code block creates copyright_decision table.
- This table is used to store user's decision.
- Similarly there are license_decision table which stores user's clearing decision for licenses.
Gaurav explained how copyright agent/user finding works.
- Agent findings contain what scanners has found, if a user makes changes in the agents finding that changes will be recorded into copyright_event table.
- For the same pfile that agent will give edited result.
- User finding table records user_decision during clearing in the UI and that content is inserted into copyright_decision table in the database.
- These clearing results are helpful during creating report.
- Scancode will also include reporting.
Avinal asked question about how to reuse an upload for different agent without reloading?
- Gaurav explained following:
- Under Jobs go to Schedule agents, there select an upload to analyse and the agent who will do analysis.
Gaurav suggested a FOSSology Using: End-to-end workflow video on YouTube.

Creating tables for scancode copyright and author.
Watch end-to-end fossology workflow video and understand fossology UI and working.

Using S instead of L for ScanCode type field in the highlight table where S will be match property of the highlight class in HighlightDao.php.
- Added a new type S in the HighlightDao.php also changed type from signature to match as like monk agent ScanCode matches text.
- Gaurav explained about identical displayed on the UI by monk scanner as, It highlight those text which are identical with the license text in the license_ref table. Whereas license relevant text means the highlighted text has been matched with license text or rules written for the license.
- So license relevant text is suitable for the ScanCode highlight.
- Also Gaurav suggested to reuse the resources already present and no need to add a new type for scancode highlight, nomos type could be reused.
Sarita(Me) shows newly created tables for scancode_copyright and scancode_author. Gaurav approved changes.

Added a function in the scancode database to insert no license in the license_file table for a code zip have no license.

  bool ScancodeDatabaseHandler::insertNoResultInDatabase(int agentId, long pFileId ){
    return saveLicenseMatch(agentId, pFileId, 320, NULL);
  }

Gaurav clarified that 320 is not constant licenseId for no-license. So instead leave licenseId null.
There is still a discussion needed (with other mentors) to decide is no license case is needed to take care for ScanCode or not.
