Indexator.NET is an application written in C# that is able to index directories and store information about the files found in a MySQL database, associating it with labels (so it can be used as a CD cataloguer). The information can be consulted in several ways: a console client, a graphical client (GTK#), asp.net Web, an asp.net service, or using remoting. It has two main objectives: to be used as a CD-ROM cataloguer, and to be used as a way to explain the possibities of Mono (and .NET) in educational environments.
