CrossGram is a publication repository for cross-linguistic data resulting from research on grammatical patterns in the world's languages. It is part of the CLLD series of projects ( Cross-Linguistic Linked Data) hosted by the Max Planck Institute for Evolutionary Anthropology since 2008 (lead developer: Robert Forkel).
All CrossGram contributions conform to the CLDF standard ( Cross-Linguistic Data Formats). A CrossGram contribution has a title, a set of authors and a year of publication and can be cited as a separate publication, though it is usually associated with a standard journal or book publication.
A CrossGram publication covers between 20 and 1200 languages, and it provides information about the languages (language parameters, l-parameters), or information about cross-linguistically comparable constructions (construction parameters, c-parameters). Each contribution includes bibliographical references about the languages, and some of the contributions include example sentences.
CrossGram is edited by Martin Haspelmath in collaboration with Johannes Englisch (Max Planck Institute for Evolutionary Anthropology).
