CLLD – Cross-Linguistic Linked Data

Publication models

There are three major ways in which the CLLD project helps publishing cross-linguistic datasets:

  1. Large databases may be published as standalone CLLD apps under the umbrella of the clld.org series; basically following the example of a book in an edited series.
  2. Smaller datasets may be submitted to one of the database journals started by the CLLD project.
  3. Datasets may be hosted independently from the CLLD project, simply re-using the clld software.

Published datasets

The following datasets are maintained by the CLLD project, i.e. fall into categories 1 and 2 above:

Update policy

CLLD datasets follow the update model of the traditional publications: Errata or additions are collected until a new edition of the dataset is released. Typically we aim to have not more than one edition per year.

But since we still want to exploit the fact that online publications could be continuously updated, we distinguish two categories of data:

Core data
represents the contributions of the dataset to research, i.e. the citeable content, e.g. value assignments in typological databases. This type of data can only be updated with a new edition, since we want to make it easy to identify and cite exact versions of a dataset.
Supplemental data
may be added to a dataset to enhance navigation within the set, or to enable visualization. Examples for this kind of data are geo-coordinates for languages, bibliographical information for sources, etc. Data in this category may be updated anytime, although we will still keep track of when and what is changed.

Data reuse

CLLD data is meant to be easily re-usable and we would love to hear about cases where it has been reused - be it in research or teaching.
