Developing Clowder Extractors
Extractors are services that run silently alongside Clowder. They can be configured to wait for specific file types to be uploaded into Clowder, and automatically execute operations on those files to extract metadata.
It is possible to develop extractors for new file types or tasks. See the NCSA Extractor Development wiki for complete instructions
Setting up a test environment for development
The NCSA Clowder wiki provides an up-to-date installation guide for Clowder.
In a fresh installation, Clowder is not configured with an email server - it does not send confirmation when someone registers for an account the confirmation email will not be sent correctly. However the Clowder console will still display the contents of the email, so the confirmation URL can be copied from there.
