caTissue Bulk Operations

It is my understanding that bulk operations can be invoked either from the caTissue web interface or from the command line. In both cases the invocation is just a trigger mechanism. A piece of caTissue functionality then picks up a local CSV file (a file with a list of comma separated values) that depicts all the changes you want to make; ie: these are the bulk part of the operation. There is another file in an XML format that in its entirety does three things:

• Describes the comma separated file
• Describes the caTissue domain objects that the changes will apply to. Note the plural: domain objects.
• Connects the csv format to the domain objects, so basically what change goes where and to what.

Both files are sent to the caTissue application for processing.
