A.Buchanan: What is the difference between the meanings of the keywords Linienöffnung and Linienräumung? Similarly, between Liniensperrung and Linienverstellung? (2015-11-29)
Henrik Juel: My guess is that Sperrung and Verstellung are synonyms, and that Öffnung and Räumung are very close, if not synonyms
(My guess is based on the Danish translations) (2015-11-29)
A.Buchanan: What would the distinction be, if any, between Öffnung and Räumung? (2015-11-30)
A.Buchanan: Following the recent successful fixing of the source and author data, the quality of the keyword (& genre) data is now the biggest fixable issue in PDB. This has two aspects (1) the definitions (2) the association to compositions. At the very least I humbly suggest let's not dig the hole deeper: (1) no one should create a new keyword without ensuring that it is not duplicating something already present. (2) No one should associate a keyword to a problem without checking that a clear underlying definition is present in at least one English. (2015-11-30)
A.Buchanan: The other thing that PDB needs is a good multi-language introduction for newcomers (including Spanish) that explains how the site works, the meaning of stipulations etc. There are too many barriers to entry for young newcomers to the chess problem world. (2015-11-30)
