# What should be the standard format for file-extension tags?

We should definitely standardize how we want to handle file-extension tags, because there's already been some confusion.

Should we have:

• .svg or svg?
• .stl or stl?
• .blend-files or blend-files?
• etc...

This is closely related to the blend-files/.blend-files synonym request, but I think we should discuss this as a more general issue.

• Tags generally avoid characters that are not either alphanumeric or a hyphen, from what I've seen on other sites. May 24 '13 at 1:21
• @ObsessiveSSOℲ: So far as I know, hyphens are used to separate words when needed. So it's not so much avoiding their use as simply not overusing them. May 24 '13 at 4:00
