Philip Greenspun illustration project/Guidelines
These are the guidelines to be used by the review group in evaluating submitted illustrations. Therefore illustrators should also use these guidelines when creating illustrations.
Three "deal breaker" guidelines:
- Must be the illustrator's original work, and the editor must release it under an acceptable free license as all content that's hosted on Wikimedia Commons is required to be.
- The illustrator must list all sources or references used, and in most cases the illustrator will be expected to use references.
- The illustration must be accurate.
- By comparison to existing reference works. (See Wikipedia's policy on verifiability.)
- File must render correctly on MediaWiki, the software used for all Wikimedia projects.
- Compliant with the librsvg library.
- Be careful with any filters, fonts, dashed lines and arrowheads, and patterns. No SVG animation is possible yet.
Other "strongly recommended" guidelines:
- Use Scalable Vector Graphics (SVG) where possible for easy adaption.
- SVG files should not contain any embedded bitmaps or raster images.
- Create language neutral illustrations (for example numbered diagrams, rather than directly labelled with text).
- Illustrators are strongly encouraged to create an alternate numbered version to go with any specific-language-labelled version. These should be properly named by adding the appropriate suffix to the same title as the numbered or non-labeled version. All language suffixes should use the ISO 639 standard language codes. (For example, add the suffix "-en.svg" for English versions, "-de.svg" for German ones, etc.)
- Illustrations should be accessible to the vision impaired (e.g. colourblindness).
- Files should not have any visible author or copyright "watermark".

Specific standards and recommendations will be developed as the project progresses.
