UNIX / Linux Tutorial for Beginners

Step 2

Deed

Question

An early 2000s beginner-friendly UNIX/Linux tutorial created by a UK-based academic is distributed under an older Creative Commons license that includes Attribution, NonCommercial, and ShareAlike conditions. Identify the exact version of the Creative Commons license used for this tutorial, and provide a comprehensive summary of (1) the freedoms granted to users, (2) the specific conditions imposed on reuse, (3) any stated limitations or disclaimers, and (4) the notice comparing this version to the newer 4.0 licenses, including the canonical URL associated with the older license version.

Answer length: 200-300 words.

Width checklist

Correct identification of the license as Creative Commons Attribution-NonCommercial-ShareAlike 2.0
Description of freedoms: Share (copy and redistribute) and Adapt (remix, transform, build upon)
Statement that freedoms are irrevocable provided terms are followed
Attribution requirement (credit, link to license, indicate changes)
NonCommercial restriction (no commercial use)
ShareAlike requirement (derivatives under same license)
No additional restrictions clause
Public domain/exception limitation note
No warranties disclaimer and mention of possible other rights (privacy, publicity, moral rights)
Notice that this is an older license version and recommendation to use 4.0 for new works
Statement that 4.0 licenses are more user-friendly and internationally robust
Canonical URL: https://creativecommons.org/licenses/by-nc-sa/2.0/

Examiner rationale

The question uses contextual clues (early 2000s UNIX/Linux beginner tutorial by a UK academic under a CC license with BY-NC-SA elements) to indirectly identify the specific license version (Deep reasoning). It then requires aggregation of multiple dispersed elements from the license deed—freedoms, conditions, disclaimers, upgrade notice, and canonical URL—ensuring broad information synthesis across the license summary (Wide scope).

Score 1 - 0

First, Deep Logic: Both agents correctly identified the license as Creative Commons Attribution-NonCommercial-ShareAlike 2.0 UK (England & Wales), matching the tutorial’s older BY-NC-SA 2.0 license. So both pass the core entity check. Next, Width/Completeness: Agent A covers more checklist elements. It explicitly mentions the irrevocability of freedoms (provided terms are followed), the “no additional restrictions” clause, and includes warranty/liability disclaimers and reference to moral/privacy rights. Agent B omits the irrevocability point and does not clearly state the “no additional restrictions” clause. While B includes the fair dealing/public domain limitation note more explicitly, overall it misses more required sub-points. Both agents provide the UK port URL instead of the canonical https://creativecommons.org/licenses/by-nc-sa/2.0/ link specified in the checklist, so neither is perfect. Finally, Presentation & User Experience: Agent A is more structured and scannable, with clearer sectioning and bold headers. It feels more like a polished search-engine-style summary. Agent B is solid but slightly less comprehensive and structured. Therefore, Agent A wins on completeness and formatting, though not at the MUCH_BETTER level due to minor checklist gaps (canonical URL issue).

The tutorial in question is the "UNIX Tutorial for Beginners" by Michael Stonebank from the University of Surrey [1]. It is distributed under the Creative Commons Attribution-NonCommercial-ShareAlike 2.0 UK: England & Wales (CC BY-NC-SA 2.0 UK) license [1][2]. Under this older license, the (1) freedoms granted allow users to "Share" (copy, distribute, and transmit the material) and "Remix" (adapt, alter, or build upon the academic work) [3]. Regarding (2) conditions on reuse, users must fulfill three primary stipulations. First, *Attribution* mandates giving appropriate credit to the author, providing a link to the license, and indicating if modifications were made [3]. Second, the *NonCommercial* clause prohibits using the educational material for commercial advantage or monetary compensation [3]. Third, the *ShareAlike* requirement dictates that if users remix, transform, or build upon the material, they must distribute their resulting contributions under the exact same, or a broadly compatible, license as the original [3]. For (3) stated limitations and disclaimers, the deed explicitly clarifies that a user's fair dealing or fair use rights, alongside other statutory copyright exceptions, are in no way affected by this license [3]. Furthermore, any conditions can be waived if formal permission is obtained directly from the copyright holder, and the author's moral rights remain fully protected [3]. Finally, the registry page displays a (4) specific notice recommending modern alternatives: "This is an older version of this license. Compared to previous versions, the 4.0 versions of all CC licenses are more user-friendly and more internationally robust. If you are licensing your own work, we strongly recommend the use of the 4.0 license instead: CC BY-NC-SA 4.0" [3]. The canonical URL associated with this exact older license version is `https://creativecommons.org/licenses/by-nc-sa/2.0/uk/` [2][3]. ## References [1] Stonebank, M.
