It is important to observe that clear, descriptive and unique file names may be important later when a metadata is combined in a directory or FTP site with other files. Avoid using file names such as mypersonaldata1.xml or data1.xml. An example of a good file name is IAI-ScientificArticle_Prog_001_Studies_999.xml , where IAI is the name of the institute, ScientificArticle represents a publication, Prog is the program acronym, 001 is the project number, Studies is a particular word or expression that represent the data, 999 is a reference number for that specific publication and .xml is the format of metadata created.
