Spreadsheeting vs Open Source Approach

Spreadsheeting Vs Open Source World

Writing Spreadsheets Applications resemble the Open Source Community in some points:

  • Free redistribution
  • You are not required to pay for each Spreadsheet application you use, neither the portion used in other Models. You can distribute your Excel Workbook without restrictions in your organization...
  • Users can make changes to the code (formulas)
  • These changes can produce slight errors that could have long life before being noticed
  • Source Code
  • The source code (formulas) is included and is visible all the times...
  • In some Excel Workbooks, you may have formulas and Vba code (not protected by password)
  • Free access to code (formulas) leads to evolution of the software over time but...Free access to code leads also to corruption of the software over time
  • Derived Works
  • The original Spreadsheet derive to other applications...
  • The original Spreadsheet is used as part of other modules
  • Errors in the source code (formulas) lead to degenerating accuracy
  • Integrity of The Author's Source Code

"Unofficial" changes can be made available but readily distinguished from the base source"...

  • When the author is gone, the code (formulas) experiment uncontrolled changes, divergent modifications don't lead to evolution (The modifier don't give back the improvements to source code)
  • No version control, nobody knows which is the source code and which version is the more tested and approved by the community of users
  • No Discrimination Against Persons or Groups

"The license must not discriminate against any person or group of persons"...

  • Managers often distribute an Excel Workbook password-protected
  • Some models send output to other workbook
