A knows B / B knows A?

We would like to offer the greatest variety of contact information.

  • We are presently presenting some 9.000 documents with information about senders and the respective receivers
  • We are listing some 300 events with information about participants
  • We could add specific contact information in the form of "A meets B" statements - we could just as well create items for any known meeting.

How do we organise such information in a way that database queries can offer us contact information with the greatest ease? How do we avoid recursive statements ("Person A meets Person B" - do we have to repeat the statement as "Person B meets Person A", and if so, how do we ensure the congruence)?

The same problem is created by membership: we have 1350 Illuminati. Ist to be an Illuminati a personal thing? Is it a thing on the account of the Order - or shall we create 1350 new items for each membership and refer to these - under what P-function?

Changing names in business succession? Use the redirect? Create different items?

See Münchner Buchhandel 1500–1850 at Wikipedia for the problem.

The Publishing House of Moritz Georg Weidmann becomes eventually the Olms Verlag - if we treat this as one company - how do we create different references for different times? Books have different imprints decade after decade - especially with the early modern practice to use the publishers' personal names in the imprints. Our system must be able to make sense of practically any imprint we find - and it should at the same moment understand how the changing imprint information is actually connected to existing companies. Munich does not have 57 companies from 1500 to 1850 but six and these are interconnected through family ties.

  • How do we give the proper picture in time segments?
  • How do we best organise data on an item that goes from 1500 to the present?
  • Should we use the Wikipedia redirect function (via merge items) to create various items that are all leading the the once central item?
  • should we create different items for each imprint and state how these items are interconnected? (if so: how do we make sure that people using the QueryService know our complex data structures?

How should we organise items that are not yet fully consolidated?

We will face a particular need to organise unconsolidated personal information and a fuzzy search for them: Documents do often just state last names. We have a place, a year, perhaps an occupation but no further information. We will need a system that gives us hints of potential matches.

  • Was it good to state names as strings?
  • Would it be more clever to create n item for each family name and to organise variants around the item (in order to understand how families belong together)?

Recipients 1, 2, 3 - a good idea?

Regular communication from members into the Illuminati Order was a complex thing. Members met one a month in their local Minerval Church and here they handed in their monthly Quibus Licet ("to whom it may concern"), a letter to be firts read by the local superior and to be passed from him to the "Unknown Superiors". The local superior of Gotha would be Christian Georg Helmolt (the first recipient), he would send the entire package of Gotha's "QQLL" (the abbreviation for the plural) to Johann Joachim Christoph Bode in Weimar (recipient 2) who could in turn pass the letters to Gotha's duke Ernest II. (recipient 3 in this case).

In order to link the respective places to which the letters were sent to the recipients I created different respective recipients which could now be spotted in different places.

One could organise this differently. User:Daniel Mietchen proposed to create an item for each transportation process. Would this be clever? How should we organise things with the aim to facilitate searches? --Olaf Simons (talk) 21:42, 6 August 2018 (CEST)

Alternative again proposed by User:Daniel Mietchen: take a look at Wikidata's P1545, series qualifier.

GND Identifyer

Why does it not work like a link as in Wikidata? Why can't we click at the number and access the dataset on the GND database?

Query Service and full years

If we enter full years with the appropriate distinction 1761-00-00etc. - why do we still get a January 1 date?

Contract between Christian Weidmann and August Bohse for 'Die unglücklich verliebte Europäerin Constantine' 1793-08-10 (Q22976) or just Q22976

FactGrid Items have an Item: prefix.

Question 1: Wikidata has a function that allows quoting items - via template, can we do that as well?

Question 2: We are in need of a good place to offer scans.Would it Q22976 be a good match to Contract between Christian Weidmann and August Bohse for 'Die unglücklich verliebte Europäerin Constantine' 1793-08-10 (Q22976) or could there be a better place for transcripts (and possibly for image files)?

tiffs and pdfs not supported

That must be in local settings php...

How would we organise contemorary sets?
