Wikipedia:WikiProject Mathematics/PlanetMath Exchange
The purpose of this subproject of Wikipedia:WikiProject Mathematics is to assist in content exchange between PlanetMath and Wikipedia.
Articles that PlanetMath has that Wikipedia does not have should be copied over if appropriate. Articles where PlanetMath has content that would benefit Wikipedia articles should be merged in as appropriate.
Instructions
Please read these very carefully.
When converting entries from PlanetMath to Wikipedia, be sure to keep in mind Wikipedia:How to write a Wikipedia article on Mathematics. That said, here are some important things to remember:
Article naming conventions
Because of naming conventions, do not create an article without searching for it first. Be sure to note the following:
- PlanetMath frequently has an entry on "some theorem" and a separate entry on "proof of some theorem". In Wikipedia these articles should generally be combined into one entry under the title "some theorem".
- When working on converting an article be sure to check the fields at the bottom of PlanetMath entries. You may see synonyms listed in other names or also defines. Check to see if we have these articles on Wikipedia first. If we don't, then add them as redirects when you convert the article over.
- Change the status of an article in the list when you have converted it. If it is redlinked and in your searching you find we already have an article, fix the link.
Converting text from PlanetMath to Wikipedia formats
PlanetMath generates article pages from LaTeX source, which needs to be pasted in a corresponding Wikipedia article. For some browsers, such as Firefox, which copy images as their "alt" text, the article can be copied directly from the article page, however this may not work for long LaTeX lines so be sure to preview and go to the page source if necessary. The newly obtained text needs to be converted to wiki markup.
- For complicated mathematical expressions, replace $ ... $ and $\displaymath ... $ with <math> ... </math> (see also help:formula). Put these on a separate line and indent as usual with a colon (:).
- For simple inline math formulas which show up as PNG images, replace LaTeX with italics, <sup> ... </sup>, <sub> ... </sub>, and Unicode characters as necessary.
- Most PlanetMath articles will need an introductory paragraph (see Wikipedia:How to write a Wikipedia article on Mathematics for an example). A motivational section, examples, applications, etc., could also be necessary.
- In some places you might consider replacing formulas with words, or simplifying them. In particular, the symbols ∈, ∃ and ∀ need to be replaced with the English words "in", "exists", "for all".
- Make relevant links to other Wikipedia articles. This can be time consuming, but is important and can help find other articles that need to be created.
- Put the article in an appropriate category.
Copyrights and attribution
- If any text is copied from a PlanetMath article to a Wikipedia article, be sure to include a link back to PlanetMath using the template {{planetmath}}. The format is as follows {{planetmath|id=planetmathID|title=planetmathTitle}} Note that the id variable is the PlanetMath article's "object ID" (which is given at the bottom of the PlanetMath page), and the title variable is the PlanetMath article title, for example the PlanetMath entry on Schinzel's theorem at http://planetmath.org/?op=getobj&from=objects&id=1115 should be specified as
- {{planetmath|id=1115|title=Schinzel's theorem}}
- which will produce
- If content of a PlanetMath article merely 'inspires' the addition of content to a Wikipedia article, the full notice from the above template may not be required. Where copyright does not apply (where content is replicated but is not verbatim or even heavily modified text), a reference to the PlanetMath article is still important (see Wikipedia:Cite sources). We should be (are!) doing this already. Similar to the above there's also a template for referencing PlanetMath articles:
- {{planetmath reference|id=1115|title=Schinzel's theorem}}
- produces

- Check the participants list at the bottom to see the areas where people are currently working so that people don't run into edit conflicts.
- When in doubt, ask a question on the talk page!
Articles lists
Each entry in the following list is a current PlanetMath article category and is a link to a list of the PlanetMath articles from that category.

Participants
If you're participating, list yourself here. Also please update this with a note saying what articles you're working on so you don't run into potential conflicts with other editors on this project.
- CryptoDerk — Watching lists to make sure they're modified by users correctly.
- Oleg Alexandrov — These days (when I find time) I work on a script to automatically update the project with new additions from PlanetPath. There is good progress.
- Ben Cairns — I'll be working primarily on articles in Probability. If I'm working on an article for a while, I'll flag it as "Work in progress".
- Paul August — I expect to be working primarily in Wikipedia:WikiProject Mathematics/PlanetMath Exchange/03-XX Mathematical logic and foundations and Wikipedia:WikiProject Mathematics/PlanetMath Exchange/54-XX General topology, but you never know ;-)
