Some notes
[edit]Just now, I decided that I will testingly start a small series addressing small things connected to my activity at Wikidata. I always make notes for myself anyway. However, some of them might be more useful for me and maybe others if I note them understandable and written out. Feel free to correct the posts or to add comments. Thanks, --Marsupium (talk) 06:30, 13 April 2014 (UTC), changed 01:19, 19 April 2014 (UTC), 09:53, 15 August 2017 (UTC)
Ordering our triples
- (Inspired by Wikidata:Requests for comment/Sort identifier statements on items that are instances of human:) External IDs could get ordered by their classes, and in one class by English label with the existing MediaWiki:Wikibase-SortedProperties. A bad start for query to get such a list this tree query ; this tree query. The question remains then how to order the classes!? …
SELECT ?prop ?propLabel ?instanceOf ?instanceOfLabel ?subclassOf ?subclassOfLabel WHERE { ?prop a wikibase:Property ; wikibase:propertyType wikibase:ExternalId. # OPTIONAL { ?prop wdt:P31 ?instanceOf. OPTIONAL { ?instanceOf wdt:P279 ?subclassOf. } # } SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". } } ORDER BY ?subclassOf ?instanceOf
- IMHO best would be to store all sort order settings in the database, also MediaWiki:Wikibase-SortedProperties. For an approach for this see http://vocab.getty.edu/doc/#Sort_Order.
- For statement claim ordering of course series ordinal (P1545), start time (P580) etc. should be evaluated!

On quality
[edit]Wikidata is growing fast. That's great. The database it is it can't be without errors. Quality has to be traded off against quantity. IMHO less quantity and more quality would be preferable. I'd like to respond to Wikipedias of which many are sceptical about Wikidata's quality and its usefulness for them[q 1] that their doubts are unfounded. I'm afraid that they are not.
There are manual editors' errors, and errors by scripts and bots, all lowering quality. I spend much of my time here with the correction of bot errors. Many of them are evitable, many even easily. I think higher standards for bots and their requests could help:
- Bots shouldn't get a flag for some task and afterwards use them for many others.
- Bots shouldn't continue with new additions if they've done harmful ones that are not yet corrected.
- Bots running with code that is not public should be a well-founded exception. It should be demanded that bot code is open source.
Rules can help with this. A culture of more effort to reduce bot errors is nicer. I appreciate all the work bot operators put into their contributions and I'd like to encourage everyone to take care, improve code, point out errors and help to eliminate them! --Marsupium (talk) 09:53, 15 August 2017 (UTC)

Collaboration on the Physical Objects Class Tree
[edit]Concerned with the progress of the Wikidata:WikiProject Visual arts I try to improve the interoperability of Wikidata with commons:Template:Artwork which was – if I remember correctly – more than 500.000 times transcluded (when [1] still showed this information). This occupation includes the mapping of commons:Template:I18n/objects to a physical object class tree on Wikidata with the help of the Art & Architecture Thesaurus (Q611299). In doing so I often enter the field of other disciplines and in the same time issues with the different language versions of Wikipedia. A great and perhaps the only possibility to create high value data will be the collaboration of projects with different domains and from different languages. The projects at WikiProject Archaeology (Q10801979) and Portal:Archaeology (Q7076022) or even de:Wikipedia:Wikidata trifft Archäologie 2013 might be those which can help the Wikidata:WikiProject Visual arts to determine if arrowhead (Q1643900) shall be a subclass of (P279) projectile point (Q2308299), and the projects at Portal:Fashion (Q13341443) might be able to help to distinguish the forms of headgear (Q14952) which caused me some trouble some weeks ago. --Marsupium (talk) 01:19, 19 April 2014 (UTC)
Some Critique of Iconclass
[edit]WARNING: This section was written some time ago. I'm afraid it contains errors I still plan to do some research on. If you think anything is not correct, I'm happy if you edit it or perhaps leave a remark. --Marsupium (talk) 09:53, 15 August 2017 (UTC)
- A – depending on the use – more or less big issue with Iconclass (Q1502787) is that it is only formalised partially. (Maybe apart from some recurring annexes) Iconclass is a monohierarchical classification. Between the time Iconclass “took shape in the early 1950s“[i 1] and its digital publication this probably did not really matter. A multihierarchical classification published in the after all mostly linear form of books would be hard to use anyway. However, at the latest now when the classification is yet published as Linked Open Data[i 2] this is a problem which reduces the value of Iconclass for Wikidata heavily. The problem gets evident through a passage of an official guide to Iconclass:
”This richness is not due to the fact that Iconclass linguistically differentiates between meanings of the word "praying". It is simply because Iconclass contains concepts that may be represented in various ways, like "public prayer" and "private prayer", but also concepts we can use to describe the visualization of prayer, like "hands folded"; and of course, many scenes of prayer from the bible, classical history and classical mythology. So, there is a fundamental difference between the word we use as a search term and the various concepts or groups of concepts that are linked to that word. This difference can be summarized in one word: context. Of course, the word "praying" has its own semantic richness, but that will never match the historical, thematic and narrative contexts which the Iconclass browser unfolds for us.“[i 3]
- Classification: The classification is shaped by the formerly paper form of Iconclass. Unfortunately the classification is monohierarchical what is an annoying limitation. Moreover the number of subclasses in a level is quite arbitrarily limited due to the use of a digit for the first two levels, a letter for the third, and again digits for the further levels.[i 4]
- Nonsense and redundancy of the classification: In consequence of the bad formalisation Iconclass lists redundant and nonsense notations and both together, there are "11F(+2) the Virgin Mary (+ Mary)" and "11F7(+2) specific aspects ~ Madonna-representations (N.B. secondary notations only) (+ Mary)".
- Formalisation: Another point where missing formalisation becomes evident are the so called "Structural Digits"[i 4] that should better be expressed explicitly.
- Controlled vocabulary: Iconclass is a controlled vocabulary. This brings the advantage with it that no unexpected values appear. With semantic web technologies open systems that are still well formalised have become possible. Especially considering the structurally necessary incompleteness of Iconclass regarding non-European art for example open systems could probably facilitate more expressive powers.
- The system of labeling main and additional minor parts of an image might be improvable by expressing the precise relationship between these parts in a formalised manner.

PPS: It seems not to be intended that some "structural digits" after a bracket cannot be given without a definite content of the bracket, the need for this can be seen in Madonna with Canon Joris van der Paele (Q2480921)depicts Iconclass notation (P1257)61B2(...)12 from https://rkd.nl/en/explore/images/2149. --Marsupium (talk) 16:59, 21 January 2019 (UTC)

- logic:
- "statement reference" qualifier (can be omitted for formulas with only one operator type), probably numbered values "1", "2" etc.
- "statements logics"/"statements relations"(?): as qualifier somewhere? (in the formula the referral statement could be represented by e.g. "THIS" (stupid idea?)) easy to complex formulas like simple "AND" (could be added as a qualifier to several) to "((2 XOR 4) AND 3) OR (1 AND NOT 5)" (how many operators shall be accepted?): not well formalized, but I don't see an alternative; TODO: find good examples and further consider with them (a less powerful alternative would be qualifiers "or" and "and", but really not expressive, error-prone and bad with information in qualifiers, so: no!)
- museum etc. place identifiers (because new items are stressful, and currently probably partly less structured ("followed by" should be used more (also by me); and "shares border with")):
- "showcase reference": see above; some differentiation for room specific vitrine references?
- "department": a department property with item datatype instead of the current method with special solution for the Louvre and others at Commons??? see 2018-12-19's Wikidata:Property proposal/organizational unit
- "patrocinium": use patron saint (P417)
