解説
問 76
- ア
正解 OSS (Open Source Software) essentially requires that the source code is made public and that users are free to modify it and redistribute it, including the modified versions (this is the core of the Open Source Definition, OSD). Therefore, choice ア (“You can modify the source code and redistribute it.”) is the correct statement. You must comply with the terms of the license (such as GPL or MIT), but the act of modifying and redistributing is itself recognized as a basic right of OSS.
Incorrectイ
The source code of OSS can often be obtained free of charge, but receiving paid maintenance support is not an obligation. Support may be offered optionally, whether paid or free, so saying you must receive it is incorrect.
Incorrectウ
OSS does not waive copyright. The author retains the copyright and grants permission by setting the conditions for use, modification, and redistribution through a license. Because you must follow the license terms, saying the copyright has been waived so it can be used without permission is incorrect.
Incorrectエ
OSS is generally provided as-is (without warranty), and there is no obligation to guarantee its operation. Regardless of whether copyright is waived, no obligation to guarantee operation arises, so the premise of the statement itself does not hold, making it incorrect.
ここがポイント
- Core of OSS (the Open Source Definition, OSD): the source code is made public, and modification and redistribution are permitted.
- OSS does not waive copyright and requires following the license terms. Even if it can be obtained free of charge, no obligation to provide support or guarantee operation is imposed.
