 One powerful feature of the RDMS is that it gives you the option to enrich your files and folders with metadata. The term **Metadata** refers to "data that provides information about other data". In other words, it is "data about data". In layman's terms, think of the information attached to a song that tells you who the singer is and which album it is from. In terms of research, this information could contain the instrument that generated the data, as well as the project or experiment that data is generated for. One powerful feature of the RDMS is that it gives you the option to enrich your files and folders with metadata.

-The RDMS is based on iRODS; short for "integrated Rule-Oriented Data System". This system treats all files and folders as data with metadata directly attached to them. The minimum level of metadata that is attached data (file/folder) is the one generated by the system itself, so called **system metadata**. This metadata contains for example the date when the data first entered the system, the size of the data and its owner. +The RDMS is based on iRODS; short for "integrated Rule-Oriented Data System".

 The second type of metadata is metadata that is added by a user, so called **user-defined metadata**. As a user, you can freely decide which metadata tags to use and how many of them to attach to the data as long as you have the required [[rdms:data:permissions|permissions]].  The second type of metadata is metadata that is added by a user, so called **user-defined metadata**.
