Editing Camel case (section)

=== Other uses ===
The [[National Information Exchange Model|NIEM]] registry requires that [[XML]] data elements use upper camel case and XML attributes use lower camel case.

Most popular [[command-line interface]]s and [[shell script|scripting]] languages cannot easily handle file names that contain embedded spaces (usually requiring the name to be put in quotes). Therefore, users of those systems often resort to camel case (or underscores, hyphens and other "safe" characters) for compound file names like <span style="font-family: monospace, monospace;">MyJobResume.pdf</span>.

==== Social media accessibility ====
[[Microblogging]] and [[social networking service]]s that limit the number of characters in a message are potential outlets for medial capitals. Using camel case between words reduces the number of spaces, and thus the number of characters, in a given message, allowing more content to fit into the limited space. [[Hashtag]]s, especially long ones, often use camel case to maintain readability (e.g. #CollegeStudentProblems is easier to read than #collegestudentproblems);<ref>{{cite web |last1=Blackwood |first1=Jessica |last2=Brown |first2=Kate |title=Accessible Use of CamelCase and Structuring Posts |url=https://ecampusontario.pressbooks.pub/accessibledigitalcontenttraining/chapter/accessible-use-of-camelcase-and-structuring-posts/ |website=Accessible Digital Content Training |publisher=McMaster University}}</ref> this practice improves [[accessibility]] as [[screen reader]]s recognize CamelCase in parsing composite hashtags.<ref>{{cite web |year=2022 |title=Social Media Accessibility Guidelines |url=https://accessibility.princeton.edu/guidelines/social-media#camelcase |url-status=dead |archive-url=https://web.archive.org/web/20221012082805/https://accessibility.princeton.edu/guidelines/social-media#camelcase |archive-date=12 October 2022 |access-date=12 October 2022 |publisher=Princeton University}}</ref>

In website URLs, spaces are [[Percent-encoding|percent-encoded]] as "%20", making the address longer and less [[human readable]]. By omitting spaces, camel case does not have this problem.
