The Cross-Linguistic Linked Data (CLLD) project coordinated over a dozen linguistics databases covering the languages of the world.
It is hosted by the Department of Linguistic and Cultural Evolution at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany (previously at the Max Planck Institute for the Science of Human History in Jena[1]).
CLLD was a project for publishing linguistic databases on the web, it ended in 2016. clld, on the other hand, is a web app framework - a piece of software.
CLDF data interfaces smoothly with clld web applications.
