Die AL wurde nicht veröffentlicht, stattdessen schreibt die 'Pittsburgh Gazette Times' (25.08.1912): "This problem seems to be cooked in 22 moves or less by a method that is not Durbar. The problem is, however, cooked, and therefore has no value in the contest or as a problem. Since there is no mainline of play, we reserve the space for the solution for other matter. Someone may be able to prove that it takes 25, or can be done in20, but what's the use."
Anton Baumann: Autorabsicht?
Wesentlich kürzer, wenn Weiss den Käfig für den sK öffnet und dafür zügig die sBB abräumt.

Korrektur
athulin: As this tourney was a correction tourney, this is a correction of
an earlier problem. The tourney book does not say which, but it may
be a correction of prb. 72 of the 1st
problem tourney ("Qui va, vient, mais ne fait rien") as +bPa3 would
be the full correction, but it is also quite close to prb. 78 ("Shoo fly!")
of the same tourney. The composer(s) of those problems are unknown, as far
as I know. (2022-07-18)

correct version of P0555591
Viktoras Paliulionis: I changed to "after TR Dawson" because that's the usual heading for such cases in other sources and databases. All databases should use unified headings for problems. "Correction", "version", and "after ..." are different things. (2021-02-23)
Viktoras Paliulionis: The person who corrected the problem or submitted a version of it is not considered a co-author; the name of the first author with a note (version ..., or correction ...) should remain above the diagram. If the problem is sufficiently reworked (as this problem), only the new author is indicated with a note "after ...". (2021-02-23)
A.Buchanan: Hi Viktoras,
Thanks for your interest in this. Oh dear, there are several things to unpack here.
(0) I do follow the Codex as exactly as possible, however...
(1) The list of names above a PDB entry is NOT necessarily a list of equal co-authors. There is no separate PDB field to record the persons who correct or improve a problem. If the names only appear in other (pure text) fields, (a) you can't validate them against the author table and (b) you can't search for them properly. So the names at the top indicate only that these individuals were associated with the problem, and in all the problems which I've ever touched the "after" field then clarifies who did what, if that's necessary, e.g. "TRD, version GF".
(2) It was genuinely an "after TRD", then it's right that TRD wouldn't appear as a name at the top.
(3) However in this case, Geoff made the new version, and was also the magazine editor. If Geoff chose to show TRD the respect of publishing his new idea as a version, then we in PDB have absolutely no right to tamper with that. Similarly, there may be cases where we disagree with what the original author and the improver have agreed together, or what an improver has unilaterally decided. But in PDB we should just report what was actually published. If you feel strongly that a classification is inappropriate, take it up with the composers first rather than going behind their backs, as you apparently have here.
(4) In many cases there is a welcome blurring over time. If "PQ, version RS" exists, then what happens if TU comes along and makes a new version? I've never seen a situation of "PQ, version RS, version TU". Pickiness of fractional ownership just doesn't matter for these things. Particularly for retros, one often finds a bunch of names all together. It's essential that each names be there, but implying a tug-of-war for fractional ownership would just be too tedious, and people often don't bother. (2021-02-23)
Viktoras Paliulionis: Andrew, of course, the database must provide accurate information. My notes:
1. In Winchloe (Christian Poisson is always very accurate in presenting information), above the diagram of this problem it says: Jeffrey Foster, after Thomas R. Dawson, The Problemist 2017. Above diagram of problem Pxxxx is written: Thomas R. Dawson, correction A. Buchanan, The Problemist 1944 (v). (Note: correction: The Problemist Supplement 2017).
2. I think Christian Poisson is right, because in the magazine there is only one author listed above each diagram.
3. How can other people know that not only the author can be specified in the "author" field?
4. Associated individuals should be noted in some other fields, because problems can be reprinted (copy-pasted) in other sources with incorrect information.
5. Instead of "PQ, RS version, TU version", it should be "PQ, TU version".
6. "The correction should be published as a joint composition only if A agrees" (codex).
7. "Bunch of names all together" often occur when they all contribute to the creation together rather than after a single author’s publication. (2021-02-23)
Viktoras Paliulionis: Mentioned problem number is P1345892. (2021-02-23)
A.Buchanan: Sorry that this is long.
PDB is not WinChloe, which has a different data model, and unilateral decisions are made by one person.
PDB is looser, a shared artifact, and is under-documented. Fields and keywords are used in varying ways. In everything I have done I have aimed for an individual’s contributions to problems to be accessible fairly, never over-stating their role.
In PDB this can only be via the “a” field and then detailed annotation elsewhere in a text field. Sometimes in the past the “comment” field has been used by people foe this but I always use the “after” field. Otherwise it is impossible to track people’s involvement and this seems to me hugely unfair, far worse than some trivial confusion over roles for what are generally not earth-shaking problems.
Ideally there would be roles of “corrector”, “versioner” etc in PDB but that’s not the case, so we have to model things with what we have.
In any area of PDB data modelling (e.g. keywords), I try identifying stakeholders and their needs and interests, and how best to serve them. Here they are old and new composers, readers, searchers, etc.
It is of course not the case that PQ v TU would always be the answer. It depends. Your suggested approach is Procrustean - we need something softer and kinder here. :-) The rules in the Codex as specified are simply not scalable to multiple applications. This is independent of the fact that PDB does not represent these rules directly.
We are not talking about album-level problems usually, we are talking about the humble, organic sharing of constructions which to me is the lifeblood of chess problem composition particularly for the newcomers who I try to introduce to PDB from social media. Let’s not over-complicate! Thanks :-) (2021-02-23)
A.Buchanan: Sorry for length, but want a single place to log my current position.
I spend some time correcting cooked old problems which are otherwise of little interest. I enjoy the connection with history, and am scrupulous never to overstate my contribution (although personally I feel that a manual correction may sometimes be more worthy than one simply using without acknowledgement a computer program to trawl for optimal arrangements of pieces). I have an open request with YACPDB to recognize roles and dependencies in their data model. I have also requested through MatPlus that WFCC regularize the unsatisfactory Codex clause handling this area, however due to well-known disruptions in the world, this has not yet happened. It is particularly an issue where the original author is deceased. But other issues are (1) non-scalability of versions (2) unilateral "aftering" (3) lack of documentation of the implications of versioning (e.g. FIDE Album) (4) consistent annotation of versions (sources, dates) etc (5) knock-on effect that databases then don't have a clear model to implement.
A little shocked to read here that Christian Poisson apparently changed a published assignment from "TRD, v GF" to "GF, after TRD". This is not what the corrector (also the editor in this case) chose to publish. While I applaud Christian's terrific work over the years, I think this example shows why it's essential to have multiple databases, so that one perspective does not predominate, and that history is not rewritten.
