Wikipedia:WikiProject Mathematics/PlanetMath Exchange

WP:PMEX

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". Usually, links to both PlanetMath articles should be included.
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. It may also be necessary to add a new article to the list of mathematical topics.

Note: There exists a tool that helps with many of the tasks above, see a few sections below.

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:

where:

The id variable is the PlanetMath article's object id, found at the bottom of the PlanetMath page.
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

which will produce

This article incorporates material from Schinzel's theorem on PlanetMath, which is licensed under the GFDL.

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. One may then use the planetmath reference template:

which produces

Schinzel's theorem on PlanetMath

Articles lists

About

PlanetMath divides its articles into categories. There is a separate category page for each category in the list. The category page lists all of the PlanetMath articles in that category, together with status information for each article. Each article that has been reviewed has been assigned a status code.

The following table lists each of the category pages, the number of articles listed there (Total), the number of those articles which have been reviewed so far (Rv), the total number of articles by status code, and when and by whom the category page was last updated.

The status codes have the following meanings:

Status Means PM article N not needed A adequately covered C copied M merged NC needs copying NM needs merging

The colours have the following meanings:

Not started Started Reviewed Complete
