Suggested minor text change in 2.7 - web-based browsers

[agbeltran]

In 2.7, it reads

"2.7 The term ‘on-line catalogue’ pertains to a computer database of metadata containing links to raw data files, that can be accessed by a variety of methods, including (but not limited to) www-based browsers."

I suggest to change "www-based browsers" to "web-based browsers".

web-based reads better to me also and thanks for the issue
