The public NDEx site includes a number of features to promote and support publishing of data in network format. Although published networks will typically be associated with research articles, there are cases where authors will decide to publish network data independently from a canonical scientific journal article. For example, researchers generating networks from large datasets using automated analytic pipelines may wish to make their results available on an ongoing basis.
For reproducibility and long term data access, NDEx offers the possibility to request DOIs for any networks. Requesting a DOI for a network ensures that the network will become a stable, immutable resource and guarantees long term access to the underlying data. In addition, the DOI can be used in subsequent publications or to submit data to online repositories.
One of the minimum annotation requirements to submit a DOI request, refers to the "Rights" metadata information. The NDEx user interface provides a number of standard licensing options you can choose from or lets you specify your own custom license in the form of a valid URL. The available options are listed below:
Adding a publication reference to a network is not required to request a DOI; this operation can be performed by the author at a later time, usually after the article referencing the network has been officially accepted for publication.
Once a DOI has been issued, that network will become a stable, non-editable resource with the exception that the author may add one publication reference: after this has been done, the network will be permanently locked and its privacy changed to PUBLIC if not already so. No more changes or updates of any kind will be allowed on this network. Any subsequent versions/updates of the network content will be in new, separate networks. For example, the author or other user could generate an editable copy using the "Clone Network" function.
