1. This flexibility may prove frustrating to advanced users and software developers who want to create or use other applications built upon data extracted from ELAN documents, such as a facility for displaying multiple aligned texts on the web. Such applications often require that all ELAN files have identical tier structures. This may be difficult when you have different people annotating different files, or even when you have multiple files with different tier configurations. It has been said many times: “The best thing about ELAN is the flexible tier structure, and the worst thing about ELAN is the flexible tier structure.” This will not be a problem for users who want to simply access the data within the ELAN window.
