== 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.
