Welcome to Wikidata, Mike Peel!

Wikidata is a free knowledge base that you can edit! It can be read and edited by humans and machines alike and you can go to any item page now and add to this ever-growing database!

Need some help getting started? Here are some pages you can familiarize yourself with:

  • Introduction – An introduction to the project.
  • Wikidata tours – Interactive tutorials to show you how Wikidata works.
  • Community portal – The portal for community members.
  • User options – including the 'Babel' extension, to set your language preferences.
  • Contents – The main help page for editing and using the site.
  • Project chat – Discussions about the project.
  • Tools – A collection of user-developed tools to allow for easier completion of some tasks.

Please remember to sign your messages on talk pages by typing four tildes (~~~~); this will automatically insert your username and the date.

If you have any questions, please ask me on my talk page. If you want to try out editing, you can use the sandbox to try. Once again, welcome, and I hope you quickly feel comfortable here, and become an active editor for Wikidata.

Best regards! —Tom Morris (talk) 13:40, 2 May 2014 (UTC)

Hi Mike. On the french version of Wikipedia, I create fr:Module:Infobox/Télescope. We speak about that in fr:Projet:Astronomie/Porte des étoiles and fr:Discussion utilisateur:Simon Villeneuve.

We should work togeter to elaborate a common infobox. Jérémy-Günther-Heinz Jähnick (talk) 12:44, 25 June 2015 (UTC)

Hi @Jérémy-Günther-Heinz Jähnick: Sorry for not getting back to you about this sooner. It's great to see that the French Wikipedia is also starting to use Wikidata for infobox content! We seem to be taking quite different technical approaches with the same aim, though: you're creating a Lua module to form the infobox in its entirety (utilizing other lua modules for the template), while I'm trying to adapt the standard en:Template:Infobox call to use information provided by en:Module:Wikidata. You're probably using the better technical solution, but copying it over to enwp is beyond what I'm currently interested in: I'm more focused on how to start getting the content onto wikidata and auto-included on wikipedia than I am about the best code/method to do this (although @RexxS: might be more interested in this).
So, perhaps it would be best if we collaborated on how to structure telescope information here on wikidata, such that both our approaches can incorporate the information? Thanks. Mike Peel (talk) 20:19, 3 July 2015 (UTC)
@Jérémy-Günther-Heinz Jähnick: I've now updated en:Template:Infobox telescope/doc to reflect the current wikidata usage by that template. I'm not currently sure what to do about linking the other parameters for the template with wikidata - any suggestions? (also @RexxS: and @Filceolaire:.) Thanks.

Hi !

I removed the area (P2046) statement because of the imprecision of the property itself : 31000 square inches is obviously the area of the mirror of the telescope, not the area of the telescope itself Face-wink.svg

I agree the size of the mirror (both the diameter, area, and even concavity) is pertinent information, and I'd love to have that on Wikidata, but we need a property specifically for it - and trust me, I looked for one (to no avail) before outright removing the statement.

@Alphos: Ah, I didn't realise there was that distinction. I'm using this parameter in en:Template:Infobox telescope for "collecting area", and thought it would be fine to use the "area" property for this. I'll propose a new property for this immediately. Please don't remove it from any other telescope articles until the info can be migrated over! Thanks. Mike Peel (talk) 21:28, 20 April 2017 (UTC)
@Alphos: Actually, before I propose a new property, what would you think to using something like applies to part (P518) -> "telescope surface" as a qualifier of the value? Where "telescope surface" is a new Wikidata entry (since one doesn't seem to exist at the moment). Would that work in place of a new property? Thanks. Mike Peel (talk) 21:38, 20 April 2017 (UTC)
I have to say it's only my opinion on the matter, and I'm just a regular user on Wikidata ; but you seem to get the distinction I'm making too, and I thank you for that !
Let's put it this way : an individual telescope worth mentionning here sits in a building, usually with a round top and a slit opening with a closable door : that building has a ground area and an office-space area. A telescope rarely stands on its end, but rather on a mechanized pedestal, which has a footprint ; and the amplitude of movement of the telescope body describes a portion of a sphere, which projects to a circle of a given area on the ground. And it of course has a mirror of a given size, which is likely the most important info about the entity. All these are areas : would you have them share a property ? From my point of view (tiny pun intended), it seems awkward that they would all be statements with the same property, no matter what qualifiers are given.
I would fully support a new property for mirror area, and would certainly also think about a property for diameter (since not all mirrors are plain disks, with some even having gaps, especially on newer, wider implements with adaptive optics) :-)
Alphos (talk) 22:30, 20 April 2017 (UTC)
If we can describe all of those areas, then that would be great, but that's a lot of areas! I'm not sure that they will be available for most telescopes, as astronomers don't tend to report those values (I say this as a professional astronomer - these areas aren't relevant for observations, but they will be present on architectural plans). For flexibility on Wikidata, it is useful to be able to add all of those values with qualifiers whenever they are available. However, dish areas is one of the important parameters of a telescope, and it is something that is often quoted (although sometimes as antenna effective area (Q571946) that depends on frequency!) so I've gone ahead and proposed Wikidata:Property proposal/Collecting area - please comment on that proposal there. :-)
Diameters are another issue... They can be extremely complex for telescopes! See Radio Astronomical Telescope Academy Nauk 600 (Q1590725) as an example, which has an annulus surface for the primary mirror, and either rectangular or conical reflectors for the secondary, and then sometimes even a tertiary mirror! So we need to be able to describe various different topologies, even if we flatten them to 2D. And that's before we get to segmented mirrors ... Thanks. Mike Peel (talk) 22:58, 20 April 2017 (UTC)
Eee-yup ! Let's not even mention segmented codependant optics like that of Q845304 or segmented optionally codependant optics like those of Q210997 (1, or 2, or 1 and 2 as an interferometer)…
Thank you for listening to my suggestion :-) Alphos (talk) 08:21, 21 April 2017 (UTC)
