UTAS data requirements and tools
UTAS library website provides guidelines on data management. It also provides | VIVO as a metadata publishing tool to create metadata records on ANDS RDA.
Data storage and publishing
UTAS is still working towards providing one data storage for all the university. Since most of the researchers and students at UTAS affiliated to the ARCCSS are part of IMAS, you can use the IMAS Data Portal . The portal provides a data submission tool to gather the necessary metadata. There's a limit to the file size you can directly upload but you can request to host bigger files which will be uploaded by a portal manager.
When you leave
I couldn't find specific answers to what happen to your access options when you don't hold anymore an account. As for others university it might be better to manage data on University repositories as a group or project, so you can always ask someone from the group to help you retrieving the data or managing the records. If your data has public access then you should be able to retrieve it from the IMAS portal. Below are the requirements about your "working data" set by the university. “ Before leaving the University, you should arrange access for at least one other researcher or your Head of School or Research Centre to the data and any documentation relating to it. Master copies of any working data that belongs to the University or to a third party with which the University has an agreement must not be removed from the University.”
