NIF Interoperation Capabilities
What is DISCO?
DISCO is an information integration approach designed to facilitate interoperation among Internet resources. It consists of a set of tools and services that allows resource providers who maintain information to share it with automated systems such as NIF. NIF is then able to “harvest” the information and keep those sets of information up-to-date.
How is this accomplished?
By using a series of files and/or scripts which are then placed in the root directory of the resource developer’s resource. (NIF can also host the files on its servers and crawl for changes there.) Once the files of the resource providers are in place, and DISCO is notified, the DISCO server can then recognize and "consume" the information shared, providing machine understandable information to NIF Integrator Servers (also known as Aggregators) about your resource.
