• Lasts for the life of the author plus an additional 50 to 100 years, depending on the jurisdiction.

Plagiarism?

Plagiarism is the act of using someone else's work, ideas, or expressions without proper acknowledgment, presenting them as one's own. It can involve copying text, images, music, or other creative content, and it is considered a serious ethical violation in academic, professional, and creative fields.

Types of Plagiarism:

1. Direct Plagiarism:

   • Copying text or content word-for-word from a source without giving credit.
   • Example: Taking a paragraph from a book or article and including it in a paper without quotation marks or citation.

2. Self-Plagiarism:

   • Reusing one's own previously published or submitted work without acknowledgment or permission.
   • Example: Submitting the same essay for different classes without informing the instructors.

3. Mosaic Plagiarism (Patchwriting):

   • Paraphrasing or mixing phrases from a source with one's own words without proper citation.
   • Example: Rearranging sentences from an article but not citing the original source.

4. Accidental Plagiarism:

   • Unintentionally failing to cite sources correctly due to a lack of understanding of citation rules.
   • Example: Forgetting to include a citation for a piece of information that was learned from a source.

5. Source-Based Plagiarism:

• Incorrectly citing a source, or citing a source that doesn’t exist, making it difficult for others to find the original material.
• Example: Citing an incorrect page number or author, or inventing a source altogether.

icensing vs. Copyright: Understanding the Difference

Copyright:

• Definition: Copyright is a legal right granted to the creator of original works, such as literature, music, art, and software, giving them exclusive control over the use, distribution, and reproduction of their work for a certain period of time.

• What it Protects: Copyright protects the expression of ideas, not the ideas themselves. It covers works like books, movies, music, software, and visual art, ensuring that only the copyright holder can reproduce, distribute, perform, or display the work.

• Duration: Copyright typically lasts for the life of the author plus an additional 50 to 100 years, depending on the country.

• Exclusive Rights: The copyright holder has the exclusive rights to:

  • Reproduce the work
  • Distribute copies of the work
  • Perform the work publicly
  • Display the work publicly
  • Create derivative works based on the original

Licensing:

• Definition: Licensing is a legal agreement in which the copyright holder (licensor) grants permission to another party (licensee) to use the copyrighted work under specific conditions, for a certain period, and usually in exchange for a fee or royalties.

• What it Involves: Licensing does not transfer ownership of the copyright; it only allows the licensee to use the work in certain ways specified in the license agreement. This can include rights to reproduce, distribute, perform, or create derivative works.

• Types of Licenses:

  • Exclusive License: Only the licensee is granted the rights to use the work in the ways specified, and even the copyright holder is restricted from using the work in those ways.
  • Non-Exclusive License: The licensee is granted rights to use the work, but the copyright holder can grant the same rights to others.
  • Sublicensing: In some cases, the licensee may have the right to grant the licensed rights to another party.

• Purpose of Licensing:

• Licensing allows the copyright holder to monetize their work by permitting others to use it while retaining ownership.
• It enables businesses, artists, and other entities to use copyrighted material without infringing on the rights of the creator.

Free and Open Source Software (FOSS) refers to software that is both freely available and open for anyone to use, modify, and distribute. Here’s a breakdown of the key concepts:

1. Free Software: This means that the software is free to use, and users have the freedom to run, study, change, and distribute the software and its source code. The term "free" refers to freedom, not price.

2. Open Source Software: The source code of the software is made available to the public, allowing anyone to inspect, modify, and enhance it. This promotes collaboration and transparency in software development.

FOSS combines these two ideas, ensuring that software is both freely accessible and open for modification, fostering a collaborative environment where developers and users can contribute to and improve the software.
