Software Server scripts are used by Polyglot to automate the interaction with software that is capable of converting from one file format to another. These scripts can directly wrap command line utilities that carry out conversions for use in Polyglot or split the steps of opening a file in one format and saving a file in a different format, typical of GUI driven applications. These wrapper scripts can be written in pretty much any text based scripting language. Below we show a few simple examples. Full details on the creation of these wrapper scripts, the required naming convensions, and required header convensions please refer to the the Scripting Manual.

Bash Script

The following is an example of a bash wrapper script for ImageMagick. Note that it is fairly straight forward. The comments at the top contain the information Polyglot needs to use the application: the name and version of the application, they type of data it supports, the input formats it supports, and the output formats it supports.

Medici Extractors

Medici extractors typically serve to automatically extract some new kind of information from a file's content when it is uploaded into Medici. These extractors do this by connecting to a shared RabbitMQ bus. When a new file is uploaded to Medici it is announced on this bus. Extractors that can handle a file of the type posted on the bus are triggered and the data they in turn create is returned to Medici as derived data to be associated with that file. The extractors themselves can be implemented in a variety of languages.
