As HTML data attributes become more popular, have people found themselves clashing with libraries that hog common names?
If so, do you use a namespace? I'd be interested to know what practices people are using.
For example a common namespacing technique from other disciplines is:
com.example.myname
e.g.
So perhaps for data- attributes it could be data-com-example-height, but that's pretty verbose.
What is the best way you have found?
This is quite subjective, so perhaps not hugely welcome on SO, but perhaps would make a nice wiki page. Feel free to vote to close if it's completely inappropriate.
It seems reasonable if you are publishing a library to prefix with e.g. the name of your library (data-foolib-bar) to avoid conflicts when redistributing. It's probably overkill for code that's not intended for redistribution.
I think that if you're running into clashes like that, it's probably a sign of overuse/abuse of data attributes.
Consider also combining them into a single attribute, eg data-foolib='{"foo":1,"bar":false}'.
